Can you use a necklace for your primary if you're a recreational diver, rather than using the necklace for the octo?

Hi, first of all, thank you for your video! 😀 I have a question. What if I'm traveling without a travel agency? Should I provide the information from the Airbnb I'll be staying in?

Sagir E Visa Egypt Country. E Visa system could not understand for Sagir Ahmed. But now Visa confirmed from Egypt country for me.

Great recap, thanks for the tips and trip report!

Awesome video! Time to sit down and get my bolt snaps in order! Thanks, Chris

Were you the only diver with a twinset?

Were you the only diver with a twinset?

Did you dye them brown

Thanks for a great video Chris. Always interesting. I know you did videos on the PADI TEC 40, 45, 50 in the past, if you have time, could you do one for the trimix 65 and 90 as well at some point? Much appreciated.

Why don’t you use standard metric that is used in literally every country on earth except us? At minimum use both if you insist of using imperial… super annoying. I mean , you maybe don’t care about the rest of the world or?

You absolutely CAN improve your consumption. Slow it down with shallower breaths more frequently. No skip breathing tho! That gives the nastiest headaches.

Thanks Chris !!!

Thanks this is very useful

What do you wear for socks? I tried to use Chuck Taylor’s but my RK3s hurt the top of my foot when I wore them.

I’m interested. Do you have a parts list or do you offer a kit? I did not see it on your website. Thanks

These would seem to work well for wet-wading anglers. Looks like they could withstand a couple mile hike-in followed by a day in a river filled with gravel, sand, and boulders. A good price compared to summer waders from fly fishing companies, and a somewhat different feature set. I have some mids on order but after seeing this I'll probably exchange them for the 8 inch version. Thanks for the sand ingress test - that's an important factor for me. Cheers!

We know you are real diver because of the mask tan.

I am interested in possibly making this mod for my back plate but where do I get the hardware (buckles) and risers?

this is the only review I could find about the Altama for their proper use, every other video about this is cringe wannabe operators wearing them for daily walkers.

Great content. I'm putting together a presentation on elite/master level training and expressing how every piece of gear/equipment needs to be fully understood and mastered by the user. I came across this and this video in conjunction with another from Scary Fascinating to give the overview of the tragedy is perfect to drive home my point. Thank you for posting.

Nice diving and the viz looks stunning. I'm used to diving in cold water and 6m (20') of viz is 'good'. I dive indy twins all the time. Why do you reverse one cylinder?

Appreciate the info!

Great informative video! Thanks for taking the time to share this information!

How many dives out of the 6 (in combination with the Adv. Nitrox) do you have to do with helium for the helitrox certification and whats the minimum helium percentage in this dives? I would like to estimate the gas costs for the course.

What is the buoyancy of this boot ?

I am going through the same process as you. Skill and costs go up exponentially so the time to get there is longer

George Irvine and others went looking for the bodies on at least 2-3 trips. I was on the boat with them on those trips. One dive was a fiasco, with one diver abandoning his scooter that stuck on. If I recall correctly, it was recovered on the bottom on a later dive. I knew the instructor - Andre - he was EXTREMELY unsafe and reckless with his diving, per my personal observation of him on several occasions. I was on an earlier dive with him where a fatality occurred and he attempted to convince myself and others to lie to the police investigators about the details of that dive (presumably to protect himself from violation of dive certification standards. As I recall reading what the survivor said.. The student was having trouble controlling his buoyancy for the whole dive, but Andre did not abort the dive early. My recollection about what the survivor reported is sketchy. I think it might have been posted on the aquanauts list server years ago. Not sure if that is archived. Also, I am also not sure if they were diving those wrecks as described int he video above, I thought they were a little deeper and I never remember hearing the searching divers describe going over any wrecks during the searches, and presumably they had the proper coordinates.

Hopefully next summer I'll do my ext range course with TDI THEN save up for CCR

Does this work with trilam drysuits.

I've written on my wetnotes with both a Milwaukee marker and a Sharpee marker. The Milwaukee ink smudged all over after just one dive. The notes written with a Sharpee are older and are still in perfect condition.

Since i wear a 14.5, should i get a size bigger or get a 14

Do those have bungee cord shoelaces? Just curious. 🤔

I think this is one of the best breakdowns of the back kick I have seen. That includes GUE and Steve Martin videos

It looks like you're swinging your weight into the rotation. Slow it down and smooth it out. It should be controlled and deliberate.

Selling a dry suit without an inflator hose is like selling a car without breaks. Should be criminally liable

Or you could just get a pair of Crocs and some wetsuit socks... By far the simplest solution...

Wanted to get these for awhile now. My boots are wet almost 6 days a week. for the price tag of these boots, I could get 3 pairs of neoprene hardsole boots that will last me 2 years or longer. just don't konw how long will the adhesives last if it's being wet all the time.

I’d love to see something like this but for deep dives (say 100m) where your O2 percentage has to be less than at the surface because your ppO2 is so high (2.31 at 100m).

Hello. Standby for an update video of the midheight version plus a review of the 8 inch tall version.

Glad I found this video. I've been looking for a diving review of these boots, thank you!

There is minimal information available on the incident as only the one diver surfaced that day. The diver who was discovered five months later on the surface was found without his rig. They actually had difficulty identifying which diver he was. I do not know if the other two divers were ever found. The major belief is that the were overweighted with all the steel tanks and that the bungees prevented the wings from inflating to the rated capacities with the dump valve releasing air. No body knows for sure what happened to the other three divers after the sole survivor lost sight of them.

Thanks for sharing! I feel that some critical part of the story must be missing. Let's do some simple calculations: The first diver had two LP95s for back gas (5380 L). He started ascending when the run time was 15 minutes, and eventually ran out of backgas when solving the buoyancy problem. I don't know how much time they spent on problem solving, let's give it a very very very loose estimation of 10 minutes after the start of the ascend (which is crazy long), rendering a total run time of 25 minutes. Suppose at this moment, he averages 230 ft (~70 m). 5380/(7+1)/25, which means he has a SAC rate of 26.9L/min (all the calculations are very conservative, in reality he may averaged over 30L/min), which is incredibly high, even higher than most OW students in their first dive. This is very unlikely to happen in hypoxic trimix level of diving. Was his back gas really full when starting the dive? What's their gas plan? Was there another gear failure? Panic? CO2 hit due to exhaustion? Hyperventilation? So many possibilities. The second doubt is, the whole story sounds like he is way overweighted. But when he ascends, his wing expands, his suit is less compressed, how can he suddenly run into buoyancy failure at a shallower depth? Also note that, when he runs out of back gas, his gears will be 10 lbs lighter than when he enters water, which means the buoyancy issue should be greatly resolved. Is it really because "the wing cannot fully expand", or is there a catastrophic buoyancy failure like a ripped wing or stuck open dump valve? We can never know. The third doubt is, even in the worst scenario where EVERYTHING on this diver failed, in a four-men team there's still way more than enough redundancy to bring him to the surface from 70m. How could this incident turn into a triple fatality? Is there other possible factors? Can it be a bad fill? Mislabeled tanks? Or a second failure on another diver? Anyway there's no way we can know what happened exactly. But these are all factors and possibilities that we should really consider when planning our own dives.

How do you keep the zippers from rusting or freezing up?

Awesome design!!!! Are you going to be at Blue Lagoon Saturday? I'm gonna try and be there for the Gigglin marlin Poker Run. Would be nice to see it and meet you.

Thanks Chris for the good video. I like your idea at 5:50 regarding the use of a double zip tie to secure the necklace to the mouthpiece. Question: My 2nd stage already has a single zip tie which secure the mouth piece to the regulator. Should I replace this with the double zip tie, or place the double zip tie in back of the single one? Thanks.

Why PADI alwayes create a horrible things?

Just did the last trimix dive before the 100. Did 91 today! AMAZING the view of the entire arch. From the 55ish ceiling arch dive, it doesn't look that big.

👍!

What a stupid idea with pony bottle, why not just use twinset ? Much much easier and better

We just sold one to a guy in Alabama. We have one currently in stock. Because of the tolerances and clearances involved, we are only selling them with the center tube and two aluminum STA bolted on already. All the fasteners are included. The system is $150. All you need are the tank bands. We also sell the correctly sized tank bands at $25 each. We are going to be up at Blue Lagoon doing a recreational backmount doubles class / refresher this saturday at 1300, if you want to see one in person.
