A couple of friends of mine down in the Keys did this really cool freediving chase scene on the Vandenburg wreck. Awesome video:cool:
Awesome vid!
Makes me really wish I had the $$$ to head to the keys for a Vandy trip.
That was really cool! Theyāre like underwater ninjas :ph34r:
Matrix H2O! That was awesome man. I loved the scene when the guy takes a ādiveā off the bow.
hereās another amazing video, this time Guillaume Nery ābase jumpingā Deans blue hole. I actually like this one better, more epic seems to be the correct word. Makes me want to get back on track in freediving so bad:fie:
I scuba dive but the longest Iāve held my breath underwater is like 30 secās. Thatās freakin amazing.
I used to be a full-time dive instructor, but only did freediving on the side whenever I could. Iām no trubridge, but Iāve hit triple digits a few times depth wise. Most of it comes down to fitness level and proper breathing. I promise you that I can take anybody off the street, spend two days with him doing no physical fitness, and double his breath hold after two days. Breath holdingis 60% mental, 35% proper breathing and 5% fitness.
that was cool 
I was a instructor for 15 years mostly on Maui/Lanai and also in the Bay Islands (Utila) and Micronesia
was a huge free diver could hit 100+ and hold 4+ minutes every/any day ahhhh to be young and in shape hehehehe
so love to watch free diving stuff
we used to go down to Cathedrals off Lanai and free dive it with no fins and run around the inside and such so that movie made me have a huge smile reminded me of my youth
we also used to go down and wear 50 lb weight belts and then climb huge walls which was fun cause you could jump a bit but not to much we would dump the belts when we wanted to go up then dive down and strap them on and start over
mostly on the walls off Lanai is where we did this like Menpachi caves etcā¦
fun to see other X instructors that enjoy free diving
its truly a way of life in the islands
where did you teach ?
Taught here in Tampa Bay, Florida. Most of my diving (due to work) was certifying new divers here in the shallow springs, and when time allowed, Iād use every minute of spare time to hit the Gulf of Mexico for some spearfishing or hit some of the less-advanced caves. Ahh, I miss that job:(
I used to SCUBA dive a whole lot and did a little bit of freediving. The funny thing about it was that holding your breath felt like it got much much easier below forty or fifty feet.
Youād get through the first set of urges to exhale at depth and reach a sort of calm.
haha, Iām totally going to kill your āsort of calmā sense at depth with this right here:D
What was happening was the law of partial pressures. As you dove deeper, the partial pressure of 02 increased in your lungs, therefore greatly lessening the urge to breathe. If you āpackedā or breathed up right before the dive getting rid of all the C02, the need to breathe lessened even more. So you keep on diving deeper thinking everything gets A-OK. Then on the way up, as the water pressure decreases, so does the partial pressure of 02. If you are not careful, youāll SWB (shallow water blackout) before you hit the surface, or when you hit the surface and exhale, youāll go out.
I know, itās a whole lot less romantic than ācalm onenessā at depth.:dance3:
I can relate to the JOB
Maui was a great place to work for sure
did intros for quite a few years way to many to count usually 3-4 groups of 4 every day off the beach !!!
not sure if you did intros ? but those are kinda fun though cause you have the chance to turn people onto diving and show them a good time get em hooked so actually enjoyed those
also taught SNUBA for a while to take over for the regular guy who got attacked by a yellow margin morey 
after they did surgery on what was left of his hand from feeding one and not knowing how ???
the video guy caught it on tape !!! 4 hours reconstructive surgery !!!
when I lived on Utila we did a ton of OW to DM work which was big down their in the early 90s at least then they would bring a Course director down to do the instructor class for them mostly Euros getting their instructor rating in a crammed program kinda like FL has in places !!
last half of my dive career or just over I mostly just lead dives which was fun especially when it was just one or two people and they were experienced divers actually got to relax and do some cool diving
after work we would go back out and dive almost every day
we had a 22 foot RIB we could use anytime we wanted so we took advantage of it free gas free boat free air bring along friends and go fishing and lobstering pretty much every night after work and have big beach luaus AHHHH the life of a dive bum
nevermind! Honu, pm sent!
What I found impressive as well was their lack of fins.
I guess itās safe to say that was filmed in segments between breathing? There is no way they could hold their breath that long with all that moving around.
Iād like to hear moreā¦ What can a layman do to increase his hold time?
They were brought down to the wreck and back up to the surface with the two scooters at the end of the video, and in between doing the filming.
So would I. (Very cool video, by the way.)
You use something called O2 and CO2 tables. The O2 tables train your body to deal better with less 02 in your system, and the CO2 tables train your body to deal better with increased amounts of CO2 in your system. CO2 is the bodies way of telling you ādumbass, you need to take a breathā The more CO2 you have built up, the greater urge you feel to take a breath.
This is why it is VERY dangerous to hyperventilate just before you go underwater. It drops the bodies level of CO2 down way low, giving you the impression that you do not need to breathe anytime soon. Problem is, 02 levels will drop faster than CO2 levels rise, so eventually youāll just āclick offā due to no oxygen, and you never saw it coming because your CO2 levels were still not high enough.
Ok, here are the tables.
CO2 TABLE

- Recover 2 mins
- Hold 3.5 mins
- Recover 2 mins
ETA: As to how I personally breathe during these tables, recovery time is spend taking veeeeery deep breaths through you mouth until you cannot inhale any more, and then try to ātop offā with a few quick "whiffs of inhaling, and exhale aaaall the way, and then do the opposite of the whiffs and try to totally empty your lungs. You want to get as much O2 in and has much CO2 out (not by hyperventilation)
As you can tell, the CO2 table is designed to decrease the amount of time you have to get CO2 out of your system, and the O2 table forces you to go longer each time. Obviously these tables are very personal, because not everybody can hold for those times right away.
Here is a good link for some āsoftwareā to help you plan it. you basically enter the info it asks for, and it will set up a custom table for you. http://apnea.cz/?software
you should have no problem doing these ādryā by yourself on the couch /in bed, put if you push yourself make sure you wonāt fall over and bust your head open. And donāt ever practice āwetā by yourself. Always have a buddy withing touching distance, and make sure he knows what signs to look for and what to do if you black out.
Thanks!
