i like the freedivers that use weights and sink soo far and then use and elevator to get back up, if both those things exist in the same underwater venue
 
woah, 88 meter thats crazy, even scuba diving to 88m is a complicated and risky business !
i've been to -31m with just fins and a mask, and its already mad deep!
 
This is absolutely insane. I'm a certified Deep Diver & 288 ft beginning to push the boundaries of what the human body can handle. My hat's off to this guy.
 
its the neoprene suit; basically its rubber with small airbubbles inside, at the surface your suit normally has some positive buoyancy and will let you float.
once you dive deeper and deeper, those airbubbles compress and your suit gets thinner and gets less buoyancy, until past a certain depth you'll have negative buoyancy and start to sink....
 
pressurizing? i think he was hyperventilating to absorb more oxygen into his blood and clear out CO2 ...
 
i think thats definitely what he was doing but it probably had some effect on the ear pressure which helped because at 88 meters there is a ton of pressure on the ears
 
you can't build up pressure to compensate 88m of depth at the surface....he'd have to build up 10bar(10atm) pressure....
that why during the dive you have to equalize pressure, normal people pinch their nose and blow out through their nose, but trained divers can equalize with a special technique called valsalva wich can be compared to dry swallowing.....
your eardrum will burst when the difference between inner and outer ear is +- 0.3bar....
 
after so many dives, your ears become so" loose" that you don't really have to do anything to equalize the pressure. they pretty much equalize on their own. i used to have to plug and blow to equalize, but now a days i don't have to do shit.
 
he is breathing like that in the beginning to enrich oxygen in his blood and get out the co2 the way his ears dont explode is because he is popping then while he dives probably every 3 feet or so
 
if i remember this correctly... basically your felt need for air is governed by how much co2 you have, not how much oxygen you dont have. so when you hyperventilate you expel a ton of co2 and basically trick your body into not "needing" to expel the co2 for longer, and maximize your time holding your breath. obviously you get a lot of oxygen too
 
i didnt even comment on the topic... yeah thats fucking nuts, free divers are nutso. ive only gone to like 120 feet or so scuba-ing, and even that's fucking cool as hell, i cant imagine what going to 88m without a tank is like..
 
the bends is generally caused from the expansion of gas inside of you(r blood vessels) for example, if you breathe in from a tank way below the surface, then while its inside you, rise to the surface, and it expands and the bubbles fuck you up. the air inside of him is what he took from the top, so it got smaller as he dove, then went back to the original size as he surfaced. . so without a tank im not too sure he has to worry about the bends...? i may be wrong on that
 
Care to elaborate what he is doing then, before you correct me ?
Like ECFreeski explained it is exactlly what i had in mind.....
but he's doing it on a very weird way so i'm not sure if he is actually hyperventilating...
if you know, feel free to tell us ....
 
btw i didnt watch the video so i dont know what was going on. i just explained what hyperventilating is (btw if you havent, try it next time youre swimming)
 
you really shouldn'tor if you do try it, make sure you have a friend who can trust watch over you.
like you mentioned you basically flush out all CO2since your breathing reflex is triggered by the amount of CO2 in the blood, and not by the amount of O2 you'll be able to postpone breathing and your O2 level will be abel to drop way below the level where you'd normally have to breath.in the best case you get a little bit light headed, but in the worst case you can suddenly black-out without warning, and drown....
so don't try this without someone who you can trust to watch over you....
 
i mean, with a little common sense you can do it.. like you said, youll get a bit lightheaded if you just do it a little. not a big deal
 
my friend who is into freediving showed me this (if any of you guys are familiar with the Island School, that where he learned) Its amazing...
But now im wondering where the music came from, there are weird sounds like a flag whipping in the wind then ripping... It must be from a movie or something
 
bingo. tricks your medula oblangata (sp?) into thinking there is less CO2 in your system than there is, so you dont subconsiously gasp for air for a much long time.

the crazy japanese pearl divers are good at it
 
one day when i become rich and famous ill buy a house in utah for winter and in the summer a house in jamaica for crazy ass dives and longboarding

mark my words
 
Holy fucksauce. That is just so fucking absurd. Fucking legend.

It seems like free soloing and free diving are very very similar as far the headspace goes. Staying relaxed and all. Crazy ass people.
 
fuck jamaica homie, buy one in Belize. 2nd largest reef in the world + the blue hole - the one of the highest per capita murder rates in the world.
