nice video. Never hyperventilate before freediving spearfishing. having said that, on dry land, I do the following apnea exercises. I do a static apnea, dynamic apnea. when i hyperventilate before dry land static apnea I can hold my breath for 3 mins 45. when i hyperventilate and do a dynamic ( burpees / starjumps ) dry land apnea I can hold my breath for 1 min 30. . when i do not hyperventilate i can do a dry land static apnea for 2 mins 30 before urge to breath. when i do not hyperventilate and do dry land dynamic apnea i can hold my breath for about 45 seconds or 1 minute. Based on this because i spearfish alone, I use my dry land dynamic apnea hold as my limit, so I limit my dives to about 45 seconds to 60 seconds (bearing in mind I do not exert my self as much as my dynamic dry land apnea hold because i try to duck dive efficiently and relax underwater when spearfishing) . i do not dive deep either, i only dive up to 10 metres. this way i feel safe and I always use the urge to breathe as my time to surface. I tend not to wait for the urge to breathe however so i surface before this. to add another note, the objective of spearfishing is to catch fish, so I tend to try and seize the opportunity to try to catch fish whilst i am snorkeling, where possible. this way i also limit the number of dives I make. if i see a nice fish in the bottom i will dive for it and i wont spend too much time down below. If i had a dive buddy then that would be a different story, i could stay down longer knowing he or she is there for me. stay safe everyone.
It's very good that you limit yourself for safety, but having a partner when diving should be non - negotiable, like wearing a helmet when riding a motorcycle or wearing a seatbelt. I would suggest searching on forums for people nearby or convincing some friend to give it a try! I know it can be hard to miss the sea, but finding a diving partner should be youn number 1 priority. If you have a trained partner you will be able to push yourself safely to greater depths and dive times. The truth is that deeper diving leads to an immensely better experience. Of course, also never do that alone. Stay safe!
Me and mate in medical school who were into spearfishing went down a rabbit hole on this. I remember dipping our heads in buckets of ice water and measuring our heart rate to measure the mammalian dive reflex & being shocked at the response.
Hi mate I’d like to have a chat with you if I can. My last two dives 8 months apart I had a palpitation / ectopic beat / lurch at around 10m. One lead to an arrhythmia and I nearly blacked out and lost feeling in my arms. The other almost lead to a black out but I recovered on the boat a lot faster. I have been diagnosed with ME/CFS several years ago and suffer all of the symptoms. I wonder if physically pushing myself too hard has caused this when I am fatigued or if possible my hiatus hernia is pushing on my heart when everything is compressed in the chest under pressure. My question is as I improve and try to overcome this disorder, I would like to discuss the potential use of beta blockers during free diving to see if they are viable or if they reduce blood pressure too much etc. If you have any advice please email me at aquaticrehabspearfishing@outlook.com
i have question. i listened chsmpion in spearfishing from italy and he says not to pull it out. becouse if you about to past out near surface you will need it to breath if there is no one fast enough to helo you cach your breath
And then when you sink or roll because you are having a hypoxic fit the snorkel can allow water into your airways if your masticatory muscles aren’t clamping hard enough.
why dont we use snorkels with a valve so that when we surface if there is swb then since the mouth is clinching onto the snorkel , the diver once out of the blackout will breathe in air?
We always spit the snorkel out when freediving because if someone blacks out you want access to the airway on the surface and easy access to rub the cheeks etc
@@AquaticRehabSpearfishing i get that but if we are diving alone, if the snorkel has a valve when we float up to the surface we can then breathe in air when we come to our senses instead of having the face in the water. the snorkels with a valve will keep the water out underwater and when the snorkel comes up above the surface it will let air in again right? what do you think of this? is it a bad idea? for people who have no choice and who spearfish alone because they dont have a dive buddy.
This is called a dry snorkel. I used one for years as I learned and found it was great at preventing mouthfuls of seawater. The downside was having to hold onto a buoyant snorkel with my teeth. My jaw used to get so sore. I would consider these training snorkels and they are great for this purpose. Now that I'm more experienced I would never go back to a dry snorkel.

I'd read the thesis on ur experiment if u guys compiled one. The results sound interesting.
@@jamesespada7146 I believe it's been largely studied already and it's pretty covered as a topic.
Awesome presentation and concise important information 👏 I hope your health is doing better brother.
Great tips man thanks for putting it together
Awesome no BS vid mate
So informative! Thank you so much!
8:10, you said keeping the earway what? didnt understnad that part.
Thanks for the guide also!
This should be titled, dangers of breath hold. Not how to.
Apologies let me change it
I agree with all that you said bro, congrats!
Welcome back
Love it, cheers for the tips

What kask you have thx
Hey! Nice video, I have subscribed patreon - but struggle to find the full length version
Any tips on this please?
You go to the tier list and scroll to the “how to spearfish series”
Why press your nose went u go down?
