FACTS the last 2 days I'll probably watch every single video by the end of the night. This shit is addicting but you will not catch me in the middle of the ocean especially in no damn underwater cave but God bless all of you🙌🏼🙌🏼🙌🏼🙏🏼🙏🏼🙏🏼🙏🏼✌🏼
I love how the guys conclusion was "nothing in a text book could have prepared us for this" Uhmm, yeah, buddy. The open water course book is pretty clear about equalizing. AOW deep dive section deals with gas narcosis and both tell you not to exceed your limits.
I did too as a kid. I started diving at 12 and I actually did my first wreck dive at 14 and it suppressed a ton of it. I didn’t want to let it rule me and honestly I was able to get over it and it’s the best thing I’ve done. Currently working on my instructor ratings and want to get my sidemount and advanced EANX! You should seriously think about trying it. You seem to show some interest watching this channel.
@@danchinoloves7804 thalassaphobia is the fear of the unknown in deep, dark waters! it can make it hard to dive in deep water, or even swim in deep water. as a child, i always imagined a killer whale suddenly appearing, coming up out of the blue towards me
I just wanna take a moment and thank you for converting feet to meters. As you said, those of us outside the US are really struggling with Imperial system of measurement😖🙃The video is great and informative as always, keep doing your job and you’ll soon achieve much more than 1000 subs:)
Not a diver or a swimmer but your channel is SO interesting. I’m an exercise physiologist so hearing y’all explain the partial pressures of different gas mixes at different depths is so freaking cool. I knew diving was intricate but I had no how idea! Thank you for the videos :)
Could you do a video showing us all the hand signs that you need to know when your diving? I know asl ( American Sign Language) and I’m really curious about that.
Some people should simply never dive. Many people think they can do it, but find they don't have the emotional stability. Some people just don't have the emotional skills
I'm a roofer that has taken absurd quantities of LSD shrooms and DMT and I also do free soloing, but I would never dive or even go spelunking. I need freedom of movement and awareness of my surroundings to feel comfortable in high risk activities. I'm also a bit claustrophobic, not really but certain spaces make me very uncomfortable like fuckin caves. Absolute madness to go into a fuckin cave especially an underwater one like WHY
i agree, but also i think some people "push their limits" too far too fast. Just watched a cave dive video where his mask was filling with water (due to a loose strap), and he panicked. his partner got him out, but it pissed him off, b/c divers should 1) have their gear in order, and 2) be comfortable in mask off situations.
"Hopefully someday you'll become a diver" No thanks, friend xD I have a huge fear of the unknown, and a huge fear of drowning. But I will educate myself because knowledge is power AND just in case anybody I know tells me they're going to cave dive uncertified with some snorkels on so I can slap them in the face with facts, knowledge, and a quick link to your channel LOL
you know, you can overcome such fears....if you try. i'd start by learning how to swim, tread-water, etc (if you dont know how to, that is) in a local swimming pool. youtube even has channels that can help you with that. i'd then advance myself and learn how to snorkel, with mask, snorkel, and fins. then try for scuba certification. gl !
Oh, I've seen this one before. They are doing their dmt. If there's one thing I don't want to hear if I go diving in South Africa is "hello I'm Waseem and I'm your dive master today."
The skills I saw in the video were not indicative of experienced divers. I think some people tend to rush through their certifications without getting the experience. In my mind there should be more scrutiny of people's experience before granting certifications. (I know that goes against the grain of making money by getting these people to sign up for more courses). Strict number of dives is not necessarily indicative of experience either. Doing 100 dives in a 15' deep lagoon doesn't completely prepare you for deep water wreck diving. Once again I see lack of buoyancy control as being as issue. Either that or people are completely overweighted. You shouldn't be kicking like made to ascend. Doing that kind of effort underwater will cause you to overbreather your regulator leading to increased CO2 creating a feeling of panic. Let your BCD or drysuit do the work, making sure to dump air as you ascend so you don't go rocketing to the surface.
I ruptured my eardrum on my first certification dive. I had a slightly stuff nose and forced my equalization way to hard cause i wasn't wise at 14. I ended up with a reverse blockage. When it ruptured i thought my sinuses had just clogged so much that the air just suddenly and painfully readjusted. The ear cavity never filled with water cause the tear was small with positive internal pressure, and i never became disoriented as a result i assume. Later during the assent, though, the pressure within kept forcing air back through the tear every 5 feet or so which felt just like the rupture but progressively worse as the wound was aggravated. It sounds like a ballon with the neck stretched to make that screeching sound. The pain was intense but fleeting and was mixed with the gratification of the pressure equalizing. Overall not as bad is i would have imagined, but again, the tear was small. The takeaway is never put extreme force into your equalization especially with a stuffy nose, and be aware that is isn't immediately obvious that your ear drum is about to fail. It can tear under less pressure than you may imagine.
Damn, this video just killed the idea of ever diving. My nose was turned to corn flake years ago. It reset in a way that restricts my breathing. Also have a buggered eardrum from the percussion of a rifle shot. That's me out I think? Still going to to watch. This channel is awesome!
I've found yawning makes me equalize. I don't know if this specific to certain people, or universal. Another possibility, for difficult equalizing, is that a cold is coming on. In that case, that dive is over the one impacted.
I am a failed diver, my ex was a Navy Clearance Diver (works at depth and with explosive ordinance, fun stuff), but I could not equalize in a pool at 6 ft. But he was a brilliant diver, he had a passion for diving and loved to teach. All these years later I still love to watch and learn about diving. Thanks so much, my head explodes even thinking of val salva.
I was the same, took me multiple different days. I called it virgin ears syndrome:). Hurt so dam bad. Finally I got it broken in and have had zero issues since. Kinda like gus, I'll pinch my nose when I get in the water, afterwards I can just "wiggle" my ears with the muscles around them and I'm good to go. Def worth getting past to dive.
Really like your channel. My, “problem” is that I can clear my ears very easily and when I took courses the instructors would “yell” at me underwater to stop and clear my ears when I already had. They all did look overweighted too.
We have the same problem Amy! And I just pretended to clear my ears, I still do that as an instructors so students remember to do it themselves. It’s a pretty awesome “problem” to have. When I’m diving with my Tech diving buddies I never equalize, they know my ears just equalize by themselves and I don’t have to pretend. 🙂
I have a hard time clearing my ears when pressure changes above water man. I was in years the time I went on an airplane and couldn't get the pressure in my ears to go away. If I went underwater and had to clear my ears at any point I can garentee you id be screwed immediately 😂 that's kind of the interesting thing about channels like this. People like me will never see the stuff this guy sees in person.
Huh. The more you know. I've always done the "pinching your nose to help with the pressure on your ears"-thing when swimming in the deep end of the pool. But I never knew how it worked. And I also didn't know it's a legit tactic while diving and that it works in those depths as well. Great explanation!
Ever since I was a kid I could make my ears click and I had no idea what that was. Later I learned it means that I have conscious control on the muscles that open my eustachian tubes. I can equalize my ears at will and I can even keep the eustachian tubes completely open a little while if I want. That useless skill is basically a super power when scuba diving or when flying planes.
Same. When I was a kid I used to just try to tense weird muscles inside my head when I was bored. Now I can wiggle my ears, raise either eyebrow independently, cross either eye while keeping the other pointed straight ahead, and equalise my ears without using my hands. Only one of those has turned out to be a useful skill...
I'm another non diver. I've always wanted to but am scared shitless of drowning. I'd be one who'd panic in 5 ft of water. I find this channel fascinating. I never knew the depth of knowledge and experience it takes to do these dives safely! I thought diving was really, really dangerous. Like sky diving or something. Thank you for schooling me! I love your videos.
I drew blood on a try dive cause of sinuses! On the morning of the dive (and last day of holidays) I woke with stuffy sinuses and slight cold. I knew my ears/sinuses were not good but hope for the best. After the guy patiently got me down into the water, past the choppy waves on the seashore and breathe calmly just under the surface, we headed down a gentle slope. I could not equalise well, but knew that if I stopped, that would be it. I wanted to try this for so long. So I pushed ahead. My ears hurt, but I failed to alert the guy, who was literally next to me. I guess I didn't want to mess the dive up or something and felt carried along by the crazy adventure of it. Anyway, suddenly my ears hissed and squealed super badly, then sudden silence, and I was fine. We went down to 11 metres or something, and I was very calm, was amazing, so much to look at, like moving through liquid glass or something. Thing is, the guy said I had blood on my lips when I surfaced. My ears were fine fortunately but there was a moral of the story... Communicate immediately if something isn't right. Some other video here you mention there should be better training for a try dive, I agree. Seems like madness that people are taken down with only a shakey grasp of what they're doing.
I was born with malformed eustachian tubes that have given me ear problems my entire life, so the sheer ENVY i feel hearing about your magic ears... indescribable Diving probably is never going to be in my future- my ears can't even equalize at sea level on a bad day, I can't imagine what a fit they'd pitch if I tried to go down too far underwater
There was a comment pointing out "nothing in the text book could have prepared us for this". Literally everything in the textbook would prepare you for that.
They're all very overweighted, too. Look at them kicking their fins and sculling their hands, all while vertical, and they're not ascending. Thus, they're very negatively buoyant. Otherwise, they'd be rocketing to surface with all that fining.
As someone whos new to understanding this whole underweight overweight thing, do you know how would one know if they're weighted correctly? Are they supposed to not sink or rise?
@@TheAnnoyingBoss usually, its based on the weight of the diver, but also other factors come into play like 1) is the diver wearing a wetsuit, 2) salt water vs fresh water, etc. if you have too little weights on weight belt, you wont be able to descend correctly. if you have too much, you will need to keep the BCD full of air at depth, or expend energy (more air from your tank) via fins to stay neutrally buoyant. having a slightly negative buoyancy at the surface is ideal.
@@TheAnnoyingBoss If I remember my training, with your lungs comfortably half full and your BCD empty, you should float with the water level just above your eyes. Basically, if you can just sink from the surfce when you fully exhale, that's the right amount of weight.
Thanks for this channel, Gus (and Woody)... I'm a dry caver "hobbyist", myself... BUT my brother, who is considerably more avid about it than me and is an outstanding member of his grotto, has already gotten my recommendation. A few years back, one of his fellow cavers brought in a "Cave Diving is Dangerous" video presentation, and while it bothered me, as some of it was clearly unsafe practices and reckless behavior and not inherent hazards of the sport "just because"... I didn't (at the time) have much cred' with his group. I hope he finds your wisdom as informative and useful as I have. It's nice to find qualified authorities on the subject who can break down incidents like you and Woody do, and dispell some of the belief in cave diving as a cavalier adventuring thing for insane adrenaline junkies and lunatics with a death-wish. I've known better for years, even that my allergies and sinus issues rarely let me engage much with deep water... BUT a lot of people don't know. Whether or not my brother or any of the members of his grotto follow through with cert's and diving a cave, I'm just glad to have a resource like this channel so they don't have to live with the worst ideas about the sport in general. You're doing GREAT WORK! AND I wish you all the best in a LONG and STORIED career of diving and caving ahead. ;o)
Honestly could listen to Gus go on and on about the science behind diving and what not forever. Definitely makes diving seem a lot less risky when you understand what is actually going on physiologically to your body and physically in regards to what water and pressure does to you. I had the chance to try diving a few years ago but I've never been able to pop my ears so I turned it down out of fear of my head exploding. I manage to free dive around 8 metres deep by holding my nose and putting pressure, ears didn't pop but it seemed to do something. I had a lot of ear infections as a kid so I think maybe i should get them checked by a specialist. Cheers Dive Talk x
I've never dived nor shown any interest in diving ever. I watched one of your videos and just became fascinated by how complex diving is. The amount of knowledge and info that goes into a topic I had literally never considered before is crazy. I still don't want to dive, but I'll continue watching. Great content.
Im personally a free diver, and after so long just focusing on going as deep as my lungs can hold for this channel definitely made me think about how much more i can explore and how much im missing by not actually going and getting certified for cave diving or even open water
Still a nope. The aquatic life forms and I have an agreement. They stay in the water unless they're going on my plate and I'll stay out of the deeps. I'll still enjoy your informational dive videos though.
I've rewatched it about 20 times and I cannot, for the life of me, figure out why Waseem just randomly swatted Doug's regulator out of his mouth for seemingly no reason whatsoever. {12:12} Who the hell responds to the "problem" gesture by slapping the potential victim across the face? Lol. I'm just glad everybody was okay.
@@dave-op2109 seems to me like this threshold is an area that should be avoided at all costs. Idk why people would go that deep if apparently you become delusional enough to just knock out each other's regulators. Good luck finding your regulator if your delusional let alone if their is other problems happening. One moment your alive, next moment you dead
@@TheAnnoyingBoss Nitrogen Narcosis isn't really a threshold but a gradient that varies between people. It's like drinking. You don't notice that you're a little impaired after one or two beers. After 5 beers you're impaired but some people will still claim they're not affected. Most people will start to feel the first signs of Narcosis around 20m. At 30-35m everybody does. You can get used to it. Just like an alcoholic can function while drunk you can function almost like normal while narced. It's a manageable problem once you get more experience so divers don't let themselves be limited by it but instead focus on making sure their gear and technique is good enough that it doesn't matter much. It's not normal to start smacking people. Most people become slow and either a bit anxious or euphoric.
As far as I can tell, it was not on purpose: he was usung his hands way too much in order to level out his lacking buoyancy (he seems to be overweighted in this dive). If you move your hands so much, although rare, it can happen that you knock out a regulator of someone nearby.
Not a diver, but swimmer and former lifeguard (pool and lake). Your natural ability to equalize your ears sounds like mine. I can "pop" my ears at will. For me, the action seems correlated to my soft pallet in some way. But I can also wiggle my ears (which they do move ever so slightly when I "pop" my ears).
Thanks to Dive Talk you can enjoy from the comfort of your couch. Also I bet there will be some wicked VR diving experiences/simulators in the near future if they don't exist already.
Thank you guys for showing to many how serious diving is and diving with your skills limits is important, so many disregarding rules of diving. I watch all you videos and so many mistakes could be avoided if rules and common sense apply to it Stay safe out there and dive safe ppl
So... The deeper you go, the harder it is to breathe in and expand your lungs? So someone with COPD should probably not go diving XD Yanno, until this channel, i thought diving was just a jump in and go thing. Had no idea about how intrinsic it was. I really thought the hardest part was swimming.
For learning the Frenzel technique for equalization you should definitely talk to Ted Harty. He is one of the best freediving instructors in the US and specifically prides himself on teaching equalization using the Frenzel technique. He runs Immersion Freediving.
I dove my first dive in japan and got hooked on it ever since, even though we didn't go too deep and myself and the dive master couldn't understand each other at all but he made sure to inform by signs that I have to be very close to him an arm distance just incase anything happen and he did stay close to me even though I ended up getting very distracted and ALOT of times epically with the corals and the beautiful marine life but he slowed down while keeping an eye on me, and even made me use his harpoon gun to catch a fish which made me very excited and happy, I had to get back and book again with him.
Ive said it previously on another video, but i dont know how i got here, im actually terrified of deep water (phalasaphobia or something) but i love the videos you guys make lol
The guy with the blackout, possible causes: Tainted air - a contaminant that made it more narcotic at depth. Something like nitrous oxide or sulphur dioxide. Both exist in exhaust fumes, and could be an issue if the air intake for the compressor that fills the tanks takes in exhaust fumes, for example proximity to a running boat diesel engine exhaust... Medication/drugs - some may have a negative interaction with pressure/nitrogen narcosis. Psychotic episode - mental health problems and diving don't mix. Just a day where he was more susceptible than usual to nitrogen narcosis - How easily you get affected by narcosis can vary from person to person, and dive to dive.
greetings from morocco , i love your channel and the reactions also the informations but i will never scuba dive :p acctually i dont go near water anymore for like 10 years now , but i love to watch videos about scuba diving specially in the blue holes i see it like a fascinating thing and how people feel when they reach the bottom " not dead of course " be safe bro and everybody plz
If you want to learn about free driving, go check out a book called Last Breath by James Nestor. It goes into a lot of the science behind it and it's a very interesting read. I'm not even a diver and I couldn't put it down.
You see the videos where folks freak hit their BCU, and almost shoot out the water like a rocket. Also why don’t these crews have like out of water training, put folks on 02, blanket if needed, glucose I don’t know 😊
Noir = the word BLACK!! 3 years high school, 2 years college FRENCH CLASSES have paid off!!! (Oh…. Wait, it says it on his shirt!!🙂🙂 but seriously, it’s the truth!! My dads $ has paid off- he would be proud! (I’m joking!🙂🙂) ……I learn more from Dive Talk than I have from any classroom, & I really appreciate them!!❤
Hi Very impressive... Just would like to make two comments... 1. Its helpful if we start equalizing early in the dive...important in the first 10 meters of decent...( pressure doubling effect) 2. Its good to know you dont need to equalize ...i am a E N T surgeon and possibly think you could be having something like a patulous eusthesian tube( PET)...WHICH IS OFCOURSE A BLESSING TO YOU provided you dont have issues when out of water... KEEP UP THE GOOD WORK...LOVING YOUR VIDEOS A LOT😊😊
Hey Gus, love this channel, being a cave diver since 2 months I found your channel and gave me so much knowledge, thank you for your works guys ! I happen to have the same natural way to decompress as yours, never understood why. The difference is that I have to activate it, less naturally, I feel I am adding pressure with the air I have in my nasal canals. Maybe we just have a different build, like in the opposite some people will never be able to decompress, and have pain at 2 meters deep. We are just lucky Keep the good work Grertings from a French intro to cave diver 🧒
I wanted to try diving when I was younger but the instructor refused to allow me to join because I was a smoker, less than half a pack a day (although I think there was more to it than that, maybe not but it doesn't matter now anyway). This was back in the mid to late 90's and I was living in Arizona at the time. I quit smoking years ago and am too damn old now so I am living vicariously through you with these videos. Thank you for you making these videos. 😁
Dude, another wicked cool video. I used to equalize the pressure in my ears holding my nose? not a big deal but not a puff of air comes out my eye if I try! OH GOD how do your eyes feel at those depths dude???
I had a girl in my class, I believe she was 11yrs old, but I remember she couldn't go down in the pool because of the pressure in her ears, even after trying to equalize it was too painful for her.. She couldn't even go forward with the class..I felt so bad for her..I think the pool was 15ft..
Hey Gus! Love the videos! You mention that you can equalize your ears naturally. I've never dove, but when I fly and my ears do the opposite, I can equalize them by just thinking about it and it makes a crackling sound. I can do that any time at will. Is that similar to your experience? I have no idea how I do it or what I'm even doing.
I am really glad I stumbled across this page! I am not a diver, but very interested in learning so I searched videos about things that could go wrong so I can make sure I am trained in these scenarios. Super super helpful that you guys do just that!! I've learned so much and I am very excited to continue to learn!
I don't like to judge, but the boat crew didn't even position him in the 'recovery position' at the surface. That position is where a person on his/her side with bottom arm positioned to hold the neck straight-ish (so it the head doesn't slump and restrict airway), top leg bent in front to keep the body from rolling forward. If a person is on his/her back (supine) and has some water left in the lungs or airway, they can re-aspirate(I think that's the term?) the water. That aspiration probably would trigger 'dry drowning', that's a thing! That lady you pointed out in the video has some steely nerves, all deliberate movements and good decisions under pressure. I agree that the entire group appeared to be non-neutral in their buoyancy. Thanks for another quality video breakdown!
Great observation! Yeah it was amazing how they just pulled him out and threw him on the “ground” and they just quit helping at that point. No recovery position, no oxygen, no attention whatsoever. It was like a body recovery, once the body hit the deck they were like “alright! We are done. Lunch?”
My ears mostly tend to equalize themselves. I've been diving for about 15 years and have about 150 or so dives. Nothing too intense. I've had reverse block at the surface and it's excruciatingly painful (sinus infection developing). I experienced reverse block at 90 feet one time. It was intense. Got my buddy's attention and let him know what was going on.... immediately began doing 2 things (this is honestly the proudest I've ever been of myself facing danger in any situation): 1) I immediately leveled off and began slowly adjusting my depth a few feet up and down to try to massage to blockage free... 2) ...and this is the most important moment in my diving career to me... I began mentally preparing myself to shatter my eardrum (knowing exactly how bad it would feel) because that's better than drowing. Fortunately it gave way within about 2 minutes and I finished the dive without issue slowly ascending the rest of the way. There wasn't a single moment to panic and I got lucky the outcome was okay. But it really really makes me appreciate what happened and why diving isn't a sport for everyone I know, and that's fine.
Man i grew up on the water and use to swim all day and night always wanted to become a diver untill i learned just how dangerous it really is my biggest fear is drowning just so much can go wrong its crazy.......this year i think ima take a class on diveing not getting any younger
It's not as dangerous as you imagine. Recreational diving has so many safeties built in that you'll live even if you break multiple rules. Many millions of people around the world do it, from children to the elderly, so it can't be that dangerous. Just do the Open Water course and see if you enjoy it.
This video probably shows the worst divers I've ever seen... They are all doing basically everything wrong, buoyancy is soo bad all have bad or actually no trim at all, using hands bad finning technique etc etc. This is why I take care about my training, educate myself beyond recreational classes and when doing training, I'll choose an instructor who is actually a good diver. If they're a tech diver as well that's already a good sign
Gus: …hopefully you’ll become a diver… Me: Oh I wish but I can’t even do a flip in the pool anymore. I think it’s my allergies? I get vertigo like 2 foot under. 🤷🏼♀️
4:06 actually you do have to equalize your lungs, precisely by breathing. This is really important. Not because you'd die if you didn't breathe for a while, but you could do significant damage way before that happens if you stop breathing, because of the pressure difference at different depths.
i did half a beginner paddy scuba course as a teen. i didnt trust the peole involved at all. so i withdrew from the course. from watchingyour videos, i made the right decision.
This is a very interesting video to me. My son, was on his very first open water dive, in Nigril Jamaica. He said he was struggling to equalize his ears. They were not going real deep.we were at Beaches resort. And this was one of the dive tours. A hurricane had just passed the area the day before. Four dolphins were in the area. And typically, they do not linger in the area. But four dolphins had followed their boat, and came back, when they entered the water. The dive group was at depth, which was on the bottom. But my son couldn’t make it all the way down. So he was above them. Not far! And the dolphins were swimming around. He tried so hard to get down with them. But the dolphins did swim around him as well. And just like you mentioned, the next day, he realized, he had a cold. So that must have been why he couldn’t equalize as well. But what a GREAT EXPERIENCE! With dolphins, on FIRST REAL DIVE !!!!
@@electrictroy2010 wtf are you on about? You can take your ignorance and go argue with someone else. You either are just a straight dick. Or, have reading comprehension issues. But my bet is BOTH. I'm not the one. Be gone.
If I was struggling with vertigo and some guy knocked my regulator out then didn't help me put it back it he'd be getting a smack on the head in the boat big time
"Advancing Diving". Sorry, but i never saw advancing divers doing that. They don't even have the basic. They act like beginner. No buddy check, no gear check. Only the instructor and the girl is asking question. They earned their situation. You can't valid "Dive mastering" when you see a video like that.
Hey Kristi, It is strongly recommended that you learn basic scuba diving techniques before venturing into caves. You really want to be comfortable using all your equipment and get your body/mind in tune with the underwater environment. That said some people have a very different approach to this, I have in mind the CDG (the Cave Diving Group in the UK). They are cavers that dives because they need to go through a flooded section of a cave in order to access to more dry passage. Very different approach. I personally know some of these guys that do not have an OW certification but are probably some of the most badass cave divers I know. So no you don't have to have an OW cert do I recommend being a diver before diving in caves? Yes, absolutely!!
I've never really had to do the nose pinch method, I can sort of adjust my jaw in the back and it does it, you hear your eardrum make a noise. I don't know how to really describe it honestly. I'm a recreational diver
I do something similar I just swallow. The action of swallowing opens your sinus and ear cavity naturally without having to force it open. Like your talking a gulp of water without the water. I've only been scuba diving once it was awesome other than being terrified by a giant lobster. However I free dive all the time not to ridiculous depths or anything no more than 60ft. If you wear a mask you still need to add air into the mask though ;-).
Kudos to Doug for posting this so people can learn. I love the script at the end: 'nothing you could learn from a text book could prepare us'. Well, I think that's the first learning point. Everything that happened should have been covered in the classroom and pool sessions both for the students and the training of the instructor and assistant/DM. As you say, these are clearly very new students. The DM and instructor should have kept a close eye on both of them, especially given their obvious lack of competence in the water on what appears to be a first boat dive in the open ocean. The bullet weights they're using are approx 2lb/0.9kg each. It's hard to see but I reckon the panicked student is wearing 14 of them, and as a rough estimate from body shape and type of suit is over-weighted by a factor of 2. Was their weighting not checked in confined water first? How to do a buoyancy check is in the book. In the water: There's a line to the wreck. Why were they not directed to use it? That should have been taught, briefed and executed. Squeezing an eardrum hurts well before it pops. Why continue down when you are in discomfort? That's certainly in the book. Signals to indicate a problem are also in the book and should have been covered in the dive brief immediately before entry - see also: keep watching your students! If you have a problem, use the line on the way up. It may be that they were going direct to the RIB to save time, but using the line takes all the task loading away from maintaing a safe ascent rate for you and your victim. See point above. As to why Waseem didn't remember the dive, going by what came out of his mouth on the boat he had ingested or inhaled a significant amount of water, and we saw he was without a regulator for a period. It could be he blacked out from hypoxia and that is known to cause short-term memory loss. Couple that with potential nitrogen narcosis when he was dicking about on the bottom! So it appears this was a cluster fugoid waiting to happen and I'd say it started in the dive centre, probably at leadership level.
@@DIVETALK Yup, the mouth piece just came apart in my mouth after biting it too hard. (I was a little nervous, can you tell?) My instructor so I signaled and showed him the mouthpiece. Honestly, I knew I needed to use the spare regulator so I did that, but not once in the training "I broke this with my teeth" was mentioned so I was drawing a blank there as to what I was supposed to do with it. 🤷🏻♀️ I didn't bite the spare nearly as hard.
I’m about get some dive carts through my job in the military and I didn’t actually wanna do it I’m a newer guy in my unit so I’m lucky I get to go to another advanced skill but I went army cause I didn’t think I could make it though navy seal training specifically the diving portion of the selection process lol. That’s just their selection I could only imagine what you do if your on an sdv team so ya that was a big factor in why I went army and now I’m getting ready to go to dive school in the army. 🤷🏼 I just think it’s neat how life has always forced me to face my fears especially when I run from them.
First of all, thank you for your service. Second, I heard the Army has more divers than the Navy, is that true? Third, I would love to attend Army Dive School just for fun! Skip all the exercising part though. :D
@@DIVETALK The Army has two major classifications of divers engineering and special operations. The engineering dive detachments make up the bulk of Army dive formations. Their primary mission is to conduct underwater engineering and disaster response. Basically, these soldiers are responsible for making bridges safe, ensuring ports and harbors are stable and clear of dangerous debris, and clearing waterways like rivers. But they can also be sent to disaster response areas where they could conduct all of the above missions as well as search and rescue to save people in distress. They also provide emergency treatment for civilian divers suffering from decompression treatment. All in all I think the army being a occupational force they do well in the water too! As does the navy!
Seems to me it should be standard procedure if there’s any question about oxygen levels, patient O2 levels should should be immediately assessed once out of the water, monitored and treated with supplemental oxygen as needed. 🤷♀️ Additionally, if it’s suspected someone got water into their lung tissue, the patient needs a chest x ray once back on dry land. I gotta say, so far, all of your videos have reaffirmed my gut that there’s no diving in my future!! 🤷♀️ Keep it up! ❤️❤️❤️
Remember they're only showing the 'scary' videos. Millions of people dive every day, children to the elderly, and it rarely goes wrong. Diving is quite safe but, like anything, there are risks that you need to be comfortable with.
Yeah my last dive was on the Mexican pride and I did not know that I had a cyst in my sinus passage it caused a reverse block on the way back up. I went back down a little tried rubbing my neck tried everything I could and it would not equalize. I eventually had to keep ascending. I’m not sure but it think it was 45 ft when my sinus exploded into my mask. Didn’t know what happened saw green liquid in my mask but as I got to the surface it turned red . Had to have surgery. Can’t really dive anymore. So I’m getting my scuba fix from you guys nowadays. Thank you for the videos! Cyst came from breaking my nose as a kid at least that was the surgeons opinion.
I needed a little longer to equalize on the way down than most divers, so I would always warn my dive partners. I'd ask them in advance if they could stay with me as I worked through my descent. They'd always say "Sure", aaannd then on the dive....nope, everyone would forget me and drop to the bottom or reef, leaving me behind. I never had a problem, thankfully, but buddies should stay with you.
Very true. In general it's better to pair up with one buddy. With more people the chance that things get forgotten or that communication degrades is higher. Definitely tell your buddy what you expect from them and yell at them if they let you down.
Ok so I’ve been swimming in the ocean my whole life but I’ve always been hesitant about learning to dive. It’s because when I try to go deeper I try the nose pinch technique and no matter how hard I try it will never equalize and is very painful. Am I just an idiot or do others have similar problems?
If you start doing it earlier, when the pressure difference isn't big yet, it's much easier. So if you can't do it, ascend a bit and try again. It's also harder if you have a cold. When you get deeper you rarely need to do it at all, but the first 5-10 meters are crucial. Don't let that hold you b a ck from trying. All scuba courses deal with this during the first classes and you're not alone. It'll work.
I am I diver on the sense I’ve been open water to furthest depth 90ft , I am completely on board for further training to be able to do cave exploration because of your videos . Five rules save lives and when in doubt exit out
I want to take a free dive class now! In barbados I was diving down to the sand out in the beach, and boy I remember that pain! I would love to learn how to properly control that
How do you not mention this? He is saying because of his vertigo he cant differenciate top or bottom. At this point you signal trouble and you immediately end the dive. Especially because of the burst eardrum. How do these fools even pass theory?!

And we adore you back!
Same! 🤙
FACTS the last 2 days I'll probably watch every single video by the end of the night. This shit is addicting but you will not catch me in the middle of the ocean especially in no damn underwater cave but God bless all of you🙌🏼🙌🏼🙌🏼🙏🏼🙏🏼🙏🏼🙏🏼✌🏼
These two individuals are highly addictive .
Same. I find myself getting pretty interested in trying diving though! Thanks to these guys. :)
I love how the guys conclusion was "nothing in a text book could have prepared us for this"
Uhmm, yeah, buddy. The open water course book is pretty clear about equalizing. AOW deep dive section deals with gas narcosis and both tell you not to exceed your limits.
Clara yeah true.
So if the eardrums broke, has he lost his hearing? That would really suck
.
@@electrictroy2010 burst eardrums usually result in temporary loss of hearing. Once it heals, hearing should return to pretty much normal .
Non Diver here watching...I'd never dive because I have thalassophobia, BUT....I can watch you lunatics do it, lol. Stay safe!
I did too as a kid. I started diving at 12 and I actually did my first wreck dive at 14 and it suppressed a ton of it. I didn’t want to let it rule me and honestly I was able to get over it and it’s the best thing I’ve done. Currently working on my instructor ratings and want to get my sidemount and advanced EANX! You should seriously think about trying it. You seem to show some interest watching this channel.
i do it *because* i have thalassophobia 😏 haha, it's a thrill!
@@Ksav_Cam I dont mean to be ignorant , what is thalassophobia and how does it affect you or your life ? 🤔
Have you been diagnosed by a doctor? Or did you just self diagnose?
@@danchinoloves7804 thalassaphobia is the fear of the unknown in deep, dark waters! it can make it hard to dive in deep water, or even swim in deep water. as a child, i always imagined a killer whale suddenly appearing, coming up out of the blue towards me
I just wanna take a moment and thank you for converting feet to meters. As you said, those of us outside the US are really struggling with Imperial system of measurement😖🙃The video is great and informative as always, keep doing your job and you’ll soon achieve much more than 1000 subs:)
Thank you! Glad you are enjoying it!
This channel will crush 1000 subs in a week or so at this pace...👍
@@DiscoveryDiversTokyo we hope so!
@DIVE TALK We should do a collab sometime...I dig the vibe of your team 👍
We in the US use metric where it counts. Our guns and bullets :)
Not a diver or a swimmer but your channel is SO interesting. I’m an exercise physiologist so hearing y’all explain the partial pressures of different gas mixes at different depths is so freaking cool. I knew diving was intricate but I had no how idea! Thank you for the videos :)
Thanks for the comment and the support. Glad you found us!
So if the eardrums broke, has he lost his hearing? That would really suck
Could you do a video showing us all the hand signs that you need to know when your diving? I know asl ( American Sign Language) and I’m really curious about that.
I was thinking the same when they talked about the sign for problem
You don't have to equalize because you were born to dive!
Some people should simply never dive. Many people think they can do it, but find they don't have the emotional stability. Some people just don't have the emotional skills
same thing with mushrooms and lsd...
@@chronicawareness9986 hahahah
I'm a roofer that has taken absurd quantities of LSD shrooms and DMT and I also do free soloing, but I would never dive or even go spelunking. I need freedom of movement and awareness of my surroundings to feel comfortable in high risk activities. I'm also a bit claustrophobic, not really but certain spaces make me very uncomfortable like fuckin caves. Absolute madness to go into a fuckin cave especially an underwater one like WHY
@@thinkinyblinko6666 imagine sky diving on lsd
i agree, but also i think some people "push their limits" too far too fast. Just watched a cave dive video where his mask was filling with water (due to a loose strap), and he panicked. his partner got him out, but it pissed him off, b/c divers should 1) have their gear in order, and 2) be comfortable in mask off situations.
*CAVE DIVER REACTS TO DIVING DISASTER:*
"And I really hope you become a diver one day"
"I hope you get inspired watching this channel"
I’m a non diver and I can’t believe you guys don’t have more followers!!! Much respect!!
Thanks for the comment and the support!
What’s that brown smudge in your user photo?
Also! If you can't equalize, go up!!! Cancel the dive!
"Hopefully someday you'll become a diver"
No thanks, friend xD
I have a huge fear of the unknown, and a huge fear of drowning. But I will educate myself because knowledge is power AND just in case anybody I know tells me they're going to cave dive uncertified with some snorkels on so I can slap them in the face with facts, knowledge, and a quick link to your channel LOL
you know, you can overcome such fears....if you try. i'd start by learning how to swim, tread-water, etc (if you dont know how to, that is) in a local swimming pool. youtube even has channels that can help you with that.
i'd then advance myself and learn how to snorkel, with mask, snorkel, and fins.
then try for scuba certification. gl !
Oh, I've seen this one before. They are doing their dmt. If there's one thing I don't want to hear if I go diving in South Africa is "hello I'm Waseem and I'm your dive master today."
Hahaha
The skills I saw in the video were not indicative of experienced divers. I think some people tend to rush through their certifications without getting the experience. In my mind there should be more scrutiny of people's experience before granting certifications. (I know that goes against the grain of making money by getting these people to sign up for more courses). Strict number of dives is not necessarily indicative of experience either. Doing 100 dives in a 15' deep lagoon doesn't completely prepare you for deep water wreck diving.
Once again I see lack of buoyancy control as being as issue. Either that or people are completely overweighted. You shouldn't be kicking like made to ascend. Doing that kind of effort underwater will cause you to overbreather your regulator leading to increased CO2 creating a feeling of panic. Let your BCD or drysuit do the work, making sure to dump air as you ascend so you don't go rocketing to the surface.
Bruh why you make your DP a picture that makes people wanna scratch their screen?
@@PoochieCollins I blew on my phone thinking it was a dog hair on the screen 😂
@@Amanda-ze2ut I love the glasses in your DP.
The more I watch, the more I am loving this channel...you guys tempt me into researching my local options for learning to dive!
Do it!
I ruptured my eardrum on my first certification dive. I had a slightly stuff nose and forced my equalization way to hard cause i wasn't wise at 14. I ended up with a reverse blockage. When it ruptured i thought my sinuses had just clogged so much that the air just suddenly and painfully readjusted. The ear cavity never filled with water cause the tear was small with positive internal pressure, and i never became disoriented as a result i assume. Later during the assent, though, the pressure within kept forcing air back through the tear every 5 feet or so which felt just like the rupture but progressively worse as the wound was aggravated. It sounds like a ballon with the neck stretched to make that screeching sound. The pain was intense but fleeting and was mixed with the gratification of the pressure equalizing. Overall not as bad is i would have imagined, but again, the tear was small. The takeaway is never put extreme force into your equalization especially with a stuffy nose, and be aware that is isn't immediately obvious that your ear drum is about to fail. It can tear under less pressure than you may imagine.
Thanks so much for sharing this with us. So glad you ended up ok. Scary stuff .
Damn, this video just killed the idea of ever diving. My nose was turned to corn flake years ago. It reset in a way that restricts my breathing. Also have a buggered eardrum from the percussion of a rifle shot. That's me out I think? Still going to to watch. This channel is awesome!
I've found yawning makes me equalize. I don't know if this specific to certain people, or universal. Another possibility, for difficult equalizing, is that a cold is coming on. In that case, that dive is over the one impacted.
I am a failed diver, my ex was a Navy Clearance Diver (works at depth and with explosive ordinance, fun stuff), but I could not equalize in a pool at 6 ft. But he was a brilliant diver, he had a passion for diving and loved to teach. All these years later I still love to watch and learn about diving. Thanks so much, my head explodes even thinking of val salva.
I was the same, took me multiple different days. I called it virgin ears syndrome:). Hurt so dam bad. Finally I got it broken in and have had zero issues since. Kinda like gus, I'll pinch my nose when I get in the water, afterwards I can just "wiggle" my ears with the muscles around them and I'm good to go. Def worth getting past to dive.
Can't help not commenting: Did you notice how much weight they have on their weightbelts?
I did! Thank you for your comments, keep them coming!
@@DIVETALK sure will!!! tks!
Really like your channel. My, “problem” is that I can clear my ears very easily and when I took courses the instructors would “yell” at me underwater to stop and clear my ears when I already had. They all did look overweighted too.
We have the same problem Amy! And I just pretended to clear my ears, I still do that as an instructors so students remember to do it themselves. It’s a pretty awesome “problem” to have.
When I’m diving with my Tech diving buddies I never equalize, they know my ears just equalize by themselves and I don’t have to pretend. 🙂
I have a hard time clearing my ears when pressure changes above water man. I was in years the time I went on an airplane and couldn't get the pressure in my ears to go away. If I went underwater and had to clear my ears at any point I can garentee you id be screwed immediately 😂 that's kind of the interesting thing about channels like this. People like me will never see the stuff this guy sees in person.
I had to stop a whole dive in Bonaire cause my ears just weren’t having it.
It happens
Huh. The more you know. I've always done the "pinching your nose to help with the pressure on your ears"-thing when swimming in the deep end of the pool. But I never knew how it worked. And I also didn't know it's a legit tactic while diving and that it works in those depths as well.
Great explanation!
Ever since I was a kid I could make my ears click and I had no idea what that was. Later I learned it means that I have conscious control on the muscles that open my eustachian tubes. I can equalize my ears at will and I can even keep the eustachian tubes completely open a little while if I want. That useless skill is basically a super power when scuba diving or when flying planes.
Yeah! It’s an odd “superpower” to have but so useful when scuba diving!
I can do that too! and i can keep them open for as long as i want.. after a few min. my toungue is in the roof of my mouth XD
Oh yeah? Well, I can spin my hands in opposite directions at the same time!
Same. When I was a kid I used to just try to tense weird muscles inside my head when I was bored. Now I can wiggle my ears, raise either eyebrow independently, cross either eye while keeping the other pointed straight ahead, and equalise my ears without using my hands. Only one of those has turned out to be a useful skill...
Mutant! 😂
A: There's a problem with my ear
B: I'll give you a problem. (knocks regulator out of his mouth)
C: I better film this guy dying
soon as you talked about ear drums, my left ear started tingling.
I'm another non diver. I've always wanted to but am scared shitless of drowning. I'd be one who'd panic in 5 ft of water. I find this channel fascinating. I never knew the depth of knowledge and experience it takes to do these dives safely! I thought diving was really, really dangerous. Like sky diving or something. Thank you for schooling me! I love your videos.
Sky diving is way safer than scuba diving for what it’s worth
I drew blood on a try dive cause of sinuses! On the morning of the dive (and last day of holidays) I woke with stuffy sinuses and slight cold. I knew my ears/sinuses were not good but hope for the best. After the guy patiently got me down into the water, past the choppy waves on the seashore and breathe calmly just under the surface, we headed down a gentle slope. I could not equalise well, but knew that if I stopped, that would be it. I wanted to try this for so long. So I pushed ahead. My ears hurt, but I failed to alert the guy, who was literally next to me. I guess I didn't want to mess the dive up or something and felt carried along by the crazy adventure of it. Anyway, suddenly my ears hissed and squealed super badly, then sudden silence, and I was fine. We went down to 11 metres or something, and I was very calm, was amazing, so much to look at, like moving through liquid glass or something. Thing is, the guy said I had blood on my lips when I surfaced. My ears were fine fortunately but there was a moral of the story... Communicate immediately if something isn't right. Some other video here you mention there should be better training for a try dive, I agree. Seems like madness that people are taken down with only a shakey grasp of what they're doing.
I was born with malformed eustachian tubes that have given me ear problems my entire life, so the sheer ENVY i feel hearing about your magic ears... indescribable
Diving probably is never going to be in my future- my ears can't even equalize at sea level on a bad day, I can't imagine what a fit they'd pitch if I tried to go down too far underwater
There was a comment pointing out "nothing in the text book could have prepared us for this".
Literally everything in the textbook would prepare you for that.
They're all very overweighted, too. Look at them kicking their fins and sculling their hands, all while vertical, and they're not ascending. Thus, they're very negatively buoyant. Otherwise, they'd be rocketing to surface with all that fining.
Absolutely! Thank you for watching.
As someone whos new to understanding this whole underweight overweight thing, do you know how would one know if they're weighted correctly? Are they supposed to not sink or rise?
@@TheAnnoyingBoss usually, its based on the weight of the diver, but also other factors come into play like 1) is the diver wearing a wetsuit, 2) salt water vs fresh water, etc. if you have too little weights on weight belt, you wont be able to descend correctly. if you have too much, you will need to keep the BCD full of air at depth, or expend energy (more air from your tank) via fins to stay neutrally buoyant.
having a slightly negative buoyancy at the surface is ideal.
Agree 100%.
@@TheAnnoyingBoss If I remember my training, with your lungs comfortably half full and your BCD empty, you should float with the water level just above your eyes. Basically, if you can just sink from the surfce when you fully exhale, that's the right amount of weight.
Thanks for this channel, Gus (and Woody)... I'm a dry caver "hobbyist", myself... BUT my brother, who is considerably more avid about it than me and is an outstanding member of his grotto, has already gotten my recommendation. A few years back, one of his fellow cavers brought in a "Cave Diving is Dangerous" video presentation, and while it bothered me, as some of it was clearly unsafe practices and reckless behavior and not inherent hazards of the sport "just because"... I didn't (at the time) have much cred' with his group.
I hope he finds your wisdom as informative and useful as I have. It's nice to find qualified authorities on the subject who can break down incidents like you and Woody do, and dispell some of the belief in cave diving as a cavalier adventuring thing for insane adrenaline junkies and lunatics with a death-wish. I've known better for years, even that my allergies and sinus issues rarely let me engage much with deep water... BUT a lot of people don't know.
Whether or not my brother or any of the members of his grotto follow through with cert's and diving a cave, I'm just glad to have a resource like this channel so they don't have to live with the worst ideas about the sport in general. You're doing GREAT WORK! AND I wish you all the best in a LONG and STORIED career of diving and caving ahead. ;o)
Really enjoying your channel! I used to do some diving, I no longer do it but still find it really interesting to watch.
Hi Ruth! Thank you for watching.
Honestly could listen to Gus go on and on about the science behind diving and what not forever. Definitely makes diving seem a lot less risky when you understand what is actually going on physiologically to your body and physically in regards to what water and pressure does to you. I had the chance to try diving a few years ago but I've never been able to pop my ears so I turned it down out of fear of my head exploding. I manage to free dive around 8 metres deep by holding my nose and putting pressure, ears didn't pop but it seemed to do something. I had a lot of ear infections as a kid so I think maybe i should get them checked by a specialist. Cheers Dive Talk x
I used to have a lot of ear infections as a kid too. I got tubes in my ears temporarily and haven't had an issue sense. Also got my tonsils removed.
Thats a nice looking wristwatch you have there!
Thank you!
I've never dived nor shown any interest in diving ever. I watched one of your videos and just became fascinated by how complex diving is. The amount of knowledge and info that goes into a topic I had literally never considered before is crazy. I still don't want to dive, but I'll continue watching. Great content.
Thanks Jordan.
Im personally a free diver, and after so long just focusing on going as deep as my lungs can hold for this channel definitely made me think about how much more i can explore and how much im missing by not actually going and getting certified for cave diving or even open water
Still a nope. The aquatic life forms and I have an agreement. They stay in the water unless they're going on my plate and I'll stay out of the deeps. I'll still enjoy your informational dive videos though.
Thank you Matt. I appreciate the feedback and thank you for watching.
I've just passed my Open Water Certification and I'm hooked on your channel. Thank you for all the time you take to put out these videos for us ❤
Congrats!
I've rewatched it about 20 times and I cannot, for the life of me, figure out why Waseem just randomly swatted Doug's regulator out of his mouth for seemingly no reason whatsoever. {12:12} Who the hell responds to the "problem" gesture by slapping the potential victim across the face? Lol. I'm just glad everybody was okay.
Pretty sure you can't figure it out because there simply is no good reason.
They are right at narcosis threshold.
@@dave-op2109 seems to me like this threshold is an area that should be avoided at all costs. Idk why people would go that deep if apparently you become delusional enough to just knock out each other's regulators. Good luck finding your regulator if your delusional let alone if their is other problems happening. One moment your alive, next moment you dead
@@TheAnnoyingBoss Nitrogen Narcosis isn't really a threshold but a gradient that varies between people. It's like drinking. You don't notice that you're a little impaired after one or two beers. After 5 beers you're impaired but some people will still claim they're not affected. Most people will start to feel the first signs of Narcosis around 20m. At 30-35m everybody does. You can get used to it. Just like an alcoholic can function while drunk you can function almost like normal while narced. It's a manageable problem once you get more experience so divers don't let themselves be limited by it but instead focus on making sure their gear and technique is good enough that it doesn't matter much.
It's not normal to start smacking people. Most people become slow and either a bit anxious or euphoric.
As far as I can tell, it was not on purpose: he was usung his hands way too much in order to level out his lacking buoyancy (he seems to be overweighted in this dive). If you move your hands so much, although rare, it can happen that you knock out a regulator of someone nearby.
Not a diver, but swimmer and former lifeguard (pool and lake).
Your natural ability to equalize your ears sounds like mine. I can "pop" my ears at will.
For me, the action seems correlated to my soft pallet in some way. But I can also wiggle my ears (which they do move ever so slightly when I "pop" my ears).
Unfortunately, I can't dive. I had surgery for a collapsed lung :(
So sorry to hear that.
Thanks to Dive Talk you can enjoy from the comfort of your couch.
Also I bet there will be some wicked VR diving experiences/simulators in the near future if they don't exist already.
Thank you guys for showing to many how serious diving is and diving with your skills limits is important, so many disregarding rules of diving. I watch all you videos and so many mistakes could be avoided if rules and common sense apply to it Stay safe out there and dive safe ppl
So... The deeper you go, the harder it is to breathe in and expand your lungs?
So someone with COPD should probably not go diving XD
Yanno, until this channel, i thought diving was just a jump in and go thing. Had no idea about how intrinsic it was. I really thought the hardest part was swimming.
Haha being a strong swimmer I've tried swimming without my hands to great success and never knew it was a good skill for diving what a fun fact thanks
You are a step ahead of the game!
For learning the Frenzel technique for equalization you should definitely talk to Ted Harty. He is one of the best freediving instructors in the US and specifically prides himself on teaching equalization using the Frenzel technique. He runs Immersion Freediving.
Non-diver here, but I still found this educational and really interesting! Thanks for sharing! (And killing those pesky lionfish!)
I dove my first dive in japan and got hooked on it ever since, even though we didn't go too deep and myself and the dive master couldn't understand each other at all but he made sure to inform by signs that I have to be very close to him an arm distance just incase anything happen and he did stay close to me even though I ended up getting very distracted and ALOT of times epically with the corals and the beautiful marine life but he slowed down while keeping an eye on me, and even made me use his harpoon gun to catch a fish which made me very excited and happy, I had to get back and book again with him.
Ive said it previously on another video, but i dont know how i got here, im actually terrified of deep water (phalasaphobia or something) but i love the videos you guys make lol
Thanks for finding us. We are glad you did.
The guy with the blackout, possible causes:
Tainted air - a contaminant that made it more narcotic at depth. Something like nitrous oxide or sulphur dioxide. Both exist in exhaust fumes, and could be an issue if the air intake for the compressor that fills the tanks takes in exhaust fumes, for example proximity to a running boat diesel engine exhaust...
Medication/drugs - some may have a negative interaction with pressure/nitrogen narcosis.
Psychotic episode - mental health problems and diving don't mix.
Just a day where he was more susceptible than usual to nitrogen narcosis - How easily you get affected by narcosis can vary from person to person, and dive to dive.
greetings from morocco , i love your channel and the reactions also the informations but i will never scuba dive :p acctually i dont go near water anymore for like 10 years now , but i love to watch videos about scuba diving specially in the blue holes i see it like a fascinating thing and how people feel when they reach the bottom " not dead of course " be safe bro and everybody plz
Thanks for subscribing and watching.
I honestly was waiting for a white shark to come into play lol
You guys convinced be to try scuba, ultimate goal combat diver hardest course in Canadian army including spec ops at 33 years old wish me luck 😂
ive been hooked on the channel for the last week, great content, id love to try diving. but money and distance are issues, much love tho
So honored to have you. Thank you!
If you want to learn about free driving, go check out a book called Last Breath by James Nestor. It goes into a lot of the science behind it and it's a very interesting read. I'm not even a diver and I couldn't put it down.
You see the videos where folks freak hit their BCU, and almost shoot out the water like a rocket. Also why don’t these crews have like out of water training, put folks on 02, blanket if needed, glucose I don’t know 😊
Noir = the word BLACK!! 3 years high school, 2 years college FRENCH CLASSES have paid off!!! (Oh…. Wait, it says it on his shirt!!🙂🙂 but seriously, it’s the truth!! My dads $ has paid off- he would be proud! (I’m joking!🙂🙂)
……I learn more from Dive Talk than I have from any classroom, & I really appreciate them!!❤
Hi
Very impressive...
Just would like to make two comments...
1. Its helpful if we start equalizing early in the dive...important in the first 10 meters of decent...( pressure doubling effect)
2. Its good to know you dont need to equalize ...i am a E N T surgeon and possibly think you could be having something like a patulous eusthesian tube( PET)...WHICH IS OFCOURSE A BLESSING TO YOU provided you dont have issues when out of water...
KEEP UP THE GOOD WORK...LOVING YOUR VIDEOS A LOT😊😊
Great input. Thanks!
I’m a diver & I can’t equalize my ears it’s so sad & frustrating
Hey Gus, love this channel, being a cave diver since 2 months I found your channel and gave me so much knowledge, thank you for your works guys !
I happen to have the same natural way to decompress as yours, never understood why.
The difference is that I have to activate it, less naturally, I feel I am adding pressure with the air I have in my nasal canals. Maybe we just have a different build, like in the opposite some people will never be able to decompress, and have pain at 2 meters deep.
We are just lucky
Keep the good work
Grertings from a French intro to cave diver 🧒
I wanted to try diving when I was younger but the instructor refused to allow me to join because I was a smoker, less than half a pack a day (although I think there was more to it than that, maybe not but it doesn't matter now anyway). This was back in the mid to late 90's and I was living in Arizona at the time. I quit smoking years ago and am too damn old now so I am living vicariously through you with these videos. Thank you for you making these videos. 😁
Dude, another wicked cool video. I used to equalize the pressure in my ears holding my nose? not a big deal but not a puff of air comes out my eye if I try! OH GOD how do your eyes feel at those depths dude???
Not a problem with eyes at depth. As long as you keep adding air to your mask you don’t feel the squeeze.
I had a girl in my class, I believe she was 11yrs old, but I remember she couldn't go down in the pool because of the pressure in her ears, even after trying to equalize it was too painful for her.. She couldn't even go forward with the class..I felt so bad for her..I think the pool was 15ft..
The equalization must be like when driving up the mountain or flying in a plane? I know some people have problems with that
Exactly
Hey Gus! Love the videos! You mention that you can equalize your ears naturally. I've never dove, but when I fly and my ears do the opposite, I can equalize them by just thinking about it and it makes a crackling sound. I can do that any time at will. Is that similar to your experience? I have no idea how I do it or what I'm even doing.
I think you must be doing the same thing I am. I don't need to move my jaw or hold my nose. I just "blow" out my ears.
I am really glad I stumbled across this page! I am not a diver, but very interested in learning so I searched videos about things that could go wrong so I can make sure I am trained in these scenarios. Super super helpful that you guys do just that!! I've learned so much and I am very excited to continue to learn!
I don't like to judge, but the boat crew didn't even position him in the 'recovery position' at the surface. That position is where a person on his/her side with bottom arm positioned to hold the neck straight-ish (so it the head doesn't slump and restrict airway), top leg bent in front to keep the body from rolling forward. If a person is on his/her back (supine) and has some water left in the lungs or airway, they can re-aspirate(I think that's the term?) the water. That aspiration probably would trigger 'dry drowning', that's a thing!
That lady you pointed out in the video has some steely nerves, all deliberate movements and good decisions under pressure. I agree that the entire group appeared to be non-neutral in their buoyancy. Thanks for another quality video breakdown!
Great observation! Yeah it was amazing how they just pulled him out and threw him on the “ground” and they just quit helping at that point. No recovery position, no oxygen, no attention whatsoever. It was like a body recovery, once the body hit the deck they were like “alright! We are done. Lunch?”
Lol "break out the beers, we have the grill lit at the dock!"
Yeah, bad reaction in the boat. Worse diving crew ever.
My ears mostly tend to equalize themselves.
I've been diving for about 15 years and have about 150 or so dives. Nothing too intense. I've had reverse block at the surface and it's excruciatingly painful (sinus infection developing).
I experienced reverse block at 90 feet one time. It was intense.
Got my buddy's attention and let him know what was going on.... immediately began doing 2 things (this is honestly the proudest I've ever been of myself facing danger in any situation):
1) I immediately leveled off and began slowly adjusting my depth a few feet up and down to try to massage to blockage free...
2) ...and this is the most important moment in my diving career to me... I began mentally preparing myself to shatter my eardrum (knowing exactly how bad it would feel) because that's better than drowing.
Fortunately it gave way within about 2 minutes and I finished the dive without issue slowly ascending the rest of the way. There wasn't a single moment to panic and I got lucky the outcome was okay.
But it really really makes me appreciate what happened and why diving isn't a sport for everyone I know, and that's fine.
Man i grew up on the water and use to swim all day and night always wanted to become a diver untill i learned just how dangerous it really is my biggest fear is drowning just so much can go wrong its crazy.......this year i think ima take a class on diveing not getting any younger
It's not as dangerous as you imagine. Recreational diving has so many safeties built in that you'll live even if you break multiple rules. Many millions of people around the world do it, from children to the elderly, so it can't be that dangerous. Just do the Open Water course and see if you enjoy it.
This video probably shows the worst divers I've ever seen... They are all doing basically everything wrong, buoyancy is soo bad all have bad or actually no trim at all, using hands bad finning technique etc etc. This is why I take care about my training, educate myself beyond recreational classes and when doing training, I'll choose an instructor who is actually a good diver. If they're a tech diver as well that's already a good sign
Gus: …hopefully you’ll become a diver…
Me: Oh I wish but I can’t even do a flip in the pool anymore. I think it’s my allergies? I get vertigo like 2 foot under. 🤷🏼♀️
4:06 actually you do have to equalize your lungs, precisely by breathing. This is really important. Not because you'd die if you didn't breathe for a while, but you could do significant damage way before that happens if you stop breathing, because of the pressure difference at different depths.
Excellent point. Thanks!
Well I'm never going diving! Although I have been in a pool once!
My nose seems to be permanently bunged up and........
I like to fart! 😂
i did half a beginner paddy scuba course as a teen. i didnt trust the peole involved at all. so i withdrew from the course. from watchingyour videos, i made the right decision.
I've heard about alien experiments that they have altered humans to be able to handle deep diving-i.e. auto-pressure equalization hmmmmm....
Watching some oldies, talking about getting close to 1k subs. Amazing where you guys are now! Keep it up!
I agree with Gus the special thing about my body is I don’t bubble because I’m a octopus 🐙
This is a very interesting video to me. My son, was on his very first open water dive, in Nigril Jamaica. He said he was struggling to equalize his ears. They were not going real deep.we were at Beaches resort. And this was one of the dive tours. A hurricane had just passed the area the day before. Four dolphins were in the area. And typically, they do not linger in the area. But four dolphins had followed their boat, and came back, when they entered the water. The dive group was at depth, which was on the bottom. But my son couldn’t make it all the way down. So he was above them. Not far! And the dolphins were swimming around. He tried so hard to get down with them. But the dolphins did swim around him as well. And just like you mentioned, the next day, he realized, he had a cold. So that must have been why he couldn’t equalize as well. But what a GREAT EXPERIENCE! With dolphins, on FIRST REAL DIVE !!!!
I’m comfused. Did the dolphins 🐬 make your kid unable to equalize? Did they attack his ears?
@@electrictroy2010 wtf are you on about? You can take your ignorance and go argue with someone else. You either are just a straight dick. Or, have reading comprehension issues. But my bet is BOTH. I'm not the one. Be gone.
Wait so why did the other guy freak out?? It wasn’t the one that had the ear drum issue right?
Eau drum guy was filming. What a weird dive.
If I was struggling with vertigo and some guy knocked my regulator out then didn't help me put it back it he'd be getting a smack on the head in the boat big time
"Advancing Diving". Sorry, but i never saw advancing divers doing that. They don't even have the basic. They act like beginner. No buddy check, no gear check. Only the instructor and the girl is asking question. They earned their situation. You can't valid "Dive mastering" when you see a video like that.
A lot of these issues can be attributed to not being a very good swimmer. A lot of people want to dive but do not have robust swimming skills
I never knew what happened to Carlos Mencia
Do you have to be an open water diver before you can be certified in cave diving?
Hey Kristi,
It is strongly recommended that you learn basic scuba diving techniques before venturing into caves. You really want to be comfortable using all your equipment and get your body/mind in tune with the underwater environment.
That said some people have a very different approach to this, I have in mind the CDG (the Cave Diving Group in the UK). They are cavers that dives because they need to go through a flooded section of a cave in order to access to more dry passage. Very different approach. I personally know some of these guys that do not have an OW certification but are probably some of the most badass cave divers I know.
So no you don't have to have an OW cert do I recommend being a diver before diving in caves?
Yes, absolutely!!
I've never really had to do the nose pinch method, I can sort of adjust my jaw in the back and it does it, you hear your eardrum make a noise. I don't know how to really describe it honestly. I'm a recreational diver
You just never wanna have to squeeze too hard. Enjoy your diving. Stay safe! Thanks for watching.
I do something similar I just swallow. The action of swallowing opens your sinus and ear cavity naturally without having to force it open. Like your talking a gulp of water without the water. I've only been scuba diving once it was awesome other than being terrified by a giant lobster. However I free dive all the time not to ridiculous depths or anything no more than 60ft. If you wear a mask you still need to add air into the mask though ;-).
Kudos to Doug for posting this so people can learn. I love the script at the end: 'nothing you could learn from a text book could prepare us'. Well, I think that's the first learning point. Everything that happened should have been covered in the classroom and pool sessions both for the students and the training of the instructor and assistant/DM.
As you say, these are clearly very new students. The DM and instructor should have kept a close eye on both of them, especially given their obvious lack of competence in the water on what appears to be a first boat dive in the open ocean.
The bullet weights they're using are approx 2lb/0.9kg each. It's hard to see but I reckon the panicked student is wearing 14 of them, and as a rough estimate from body shape and type of suit is over-weighted by a factor of 2. Was their weighting not checked in confined water first? How to do a buoyancy check is in the book.
In the water:
There's a line to the wreck. Why were they not directed to use it? That should have been taught, briefed and executed.
Squeezing an eardrum hurts well before it pops. Why continue down when you are in discomfort? That's certainly in the book.
Signals to indicate a problem are also in the book and should have been covered in the dive brief immediately before entry - see also: keep watching your students!
If you have a problem, use the line on the way up. It may be that they were going direct to the RIB to save time, but using the line takes all the task loading away from maintaing a safe ascent rate for you and your victim. See point above.
As to why Waseem didn't remember the dive, going by what came out of his mouth on the boat he had ingested or inhaled a significant amount of water, and we saw he was without a regulator for a period. It could be he blacked out from hypoxia and that is known to cause short-term memory loss. Couple that with potential nitrogen narcosis when he was dicking about on the bottom!
So it appears this was a cluster fugoid waiting to happen and I'd say it started in the dive centre, probably at leadership level.
If you see half of the divegroup with splitfins, you know you are in trouble! :D
Hahaha it definitely could be a red flag
Whenever I go on a plane or up a mountain in a car by ear pop automatically too.. not sure if that's the same thing or not
And here I thought biting right through my regulator on my first dive was bad.
Through the mouth piece? So what did you do?
@@DIVETALK Yup, the mouth piece just came apart in my mouth after biting it too hard. (I was a little nervous, can you tell?)
My instructor so I signaled and showed him the mouthpiece.
Honestly, I knew I needed to use the spare regulator so I did that, but not once in the training "I broke this with my teeth" was mentioned so I was drawing a blank there as to what I was supposed to do with it. 🤷🏻♀️
I didn't bite the spare nearly as hard.
I’m about get some dive carts through my job in the military and I didn’t actually wanna do it I’m a newer guy in my unit so I’m lucky I get to go to another advanced skill but I went army cause I didn’t think I could make it though navy seal training specifically the diving portion of the selection process lol. That’s just their selection I could only imagine what you do if your on an sdv team so ya that was a big factor in why I went army and now I’m getting ready to go to dive school in the army. 🤷🏼 I just think it’s neat how life has always forced me to face my fears especially when I run from them.
First of all, thank you for your service.
Second, I heard the Army has more divers than the Navy, is that true?
Third, I would love to attend Army Dive School just for fun! Skip all the exercising part though. :D
@@DIVETALK The Army has two major classifications of divers engineering and special operations. The engineering dive detachments make up the bulk of Army dive formations. Their primary mission is to conduct underwater engineering and disaster response.
Basically, these soldiers are responsible for making bridges safe, ensuring ports and harbors are stable and clear of dangerous debris, and clearing waterways like rivers. But they can also be sent to disaster response areas where they could conduct all of the above missions as well as search and rescue to save people in distress. They also provide emergency treatment for civilian divers suffering from decompression treatment. All in all I think the army being a occupational force they do well in the water too! As does the navy!
Seems to me it should be standard procedure if there’s any question about oxygen levels, patient O2 levels should should be immediately assessed once out of the water, monitored and treated with supplemental oxygen as needed. 🤷♀️ Additionally, if it’s suspected someone got water into their lung tissue, the patient needs a chest x ray once back on dry land. I gotta say, so far, all of your videos have reaffirmed my gut that there’s no diving in my future!! 🤷♀️ Keep it up! ❤️❤️❤️
Remember they're only showing the 'scary' videos. Millions of people dive every day, children to the elderly, and it rarely goes wrong. Diving is quite safe but, like anything, there are risks that you need to be comfortable with.
Yeah my last dive was on the Mexican pride and I did not know that I had a cyst in my sinus passage it caused a reverse block on the way back up.
I went back down a little tried rubbing my neck tried everything I could and it would not equalize. I eventually had to keep ascending. I’m not sure but it think it was 45 ft when my sinus exploded into my mask. Didn’t know what happened saw green liquid in my mask but as I got to the surface it turned red . Had to have surgery. Can’t really dive anymore. So I’m getting my scuba fix from you guys nowadays. Thank you for the videos! Cyst came from breaking my nose as a kid at least that was the surgeons opinion.
Thanks for watching!
I have busted my ear drum a couple of times. It hurts a lot and sucks.
I needed a little longer to equalize on the way down than most divers, so I would always warn my dive partners. I'd ask them in advance if they could stay with me as I worked through my descent. They'd always say "Sure", aaannd then on the dive....nope, everyone would forget me and drop to the bottom or reef, leaving me behind. I never had a problem, thankfully, but buddies should stay with you.
Very true. In general it's better to pair up with one buddy. With more people the chance that things get forgotten or that communication degrades is higher. Definitely tell your buddy what you expect from them and yell at them if they let you down.
Very interesting and informative! Thanks for explaining it all so well!
Where is Woody? I haven't seen him in the last couple videos
Ok so I’ve been swimming in the ocean my whole life but I’ve always been hesitant about learning to dive. It’s because when I try to go deeper I try the nose pinch technique and no matter how hard I try it will never equalize and is very painful. Am I just an idiot or do others have similar problems?
If you start doing it earlier, when the pressure difference isn't big yet, it's much easier. So if you can't do it, ascend a bit and try again. It's also harder if you have a cold. When you get deeper you rarely need to do it at all, but the first 5-10 meters are crucial. Don't let that hold you b a ck from trying. All scuba courses deal with this during the first classes and you're not alone. It'll work.
I am I diver on the sense I’ve been open water to furthest depth 90ft , I am completely on board for further training to be able to do cave exploration because of your videos . Five rules save lives and when in doubt exit out
I want to take a free dive class now! In barbados I was diving down to the sand out in the beach, and boy I remember that pain! I would love to learn how to properly control that
I always had to take extra time to equalize my ears and my friend who dove with me could easily descend as fast as he wanted, I was always jealous.
How do you not mention this? He is saying because of his vertigo he cant differenciate top or bottom. At this point you signal trouble and you immediately end the dive. Especially because of the burst eardrum. How do these fools even pass theory?!
