"Free Fall" - the coolest underwater video you'll ever see

Ok, maybe an exageration, but whatever. Enjoy it.


Guillaume Nery free diving "Dean's Blue Hole"

Dean's Blue Hole is the world's deepest known blue hole with seawater.[1] It plunges 202 metres (663 ft) in a bay west of Clarence Town on Long Island, Bahamas

Awesome!

Aliens made that hole!

[mikec]

That's kickass!

Wonder how many pulls off the other divers air tanks he had to take? Hard to believe that anyone could hold it for that long, especially with the exertion expended on the trip back topside...

Top level free divers hold their breath for 4+ minutes and go down 300+ ft (and back up, obv) without assistance.

In the first 30 or so feet underwater, the lungs, full of air, buoy your body to the surface, requiring strenuous paddling and constant equalization of the middle-ear cavities to gain depth. “This is where you use up to 15 percent of your energy,” Trubridge says. And you’ve still got 600 feet of swimming to go.

As you dive past 30 feet, you feel the pressure on your body double, compressing your lungs to about half their normal size. You suddenly feel weightless, your body suspended in a gravityless state called neutral buoyancy. Then something amazing happens: as you keep diving, the ocean no longer pushes your body toward the surface but instead pulls you relentlessly toward the seafloor below. You place your arms at your sides in a skydiver pose and effortlessly go deeper.

At 100 feet, the pressure has quadrupled, the ocean’s surface is barely visible, and you close your eyes and prepare for the deep water’s tightening clutch.

Further still, at 150 feet, you enter a dream state caused by the high levels of carbon dioxide and nitrogen gas in your bloodstream: for a moment, you can forget where you are and why. At 300 feet, the pressure is so extreme that your lungs shrink to the size of oranges and your heart beats at less than half its normal rate to conserve oxygen. You lose some motor control. Most of the blood in your arms and legs has flooded to your body’s core as the vessels in your extremities constrict. Vessels in your lungs swell to several times their normal size so they won’t be crushed by the incredible pressure.

Then comes the really hard part. You open your eyes, struggle to force your semiparalyzed hand to grab a ticket from the plate, and head back up. With the ocean’s weight working against you, you tap your meager energy reserves to swim toward the surface. Ascending to 200 feet, 150 feet, 100 feet, your lungs ache with an almost unbearable desire to breathe, your vision fades, and your chest convulses from the buildup of carbon dioxide in your bloodstream. You need to hurry before you black out. Above you, the haze of blue water transforms into a sheen of sunlight on the water’s surface. You’re going to make it.

You resurface, the world spins, people are yelling at you to breathe. Is this just another altered-state dream? It’s hard to tell. So you sit there, whacked out, trying to come to quickly enough to complete the surface protocol. You take off your goggles, flick a sign, say “I’m OK”—then you get out of the way and make room for the next diver.

That's quite breathtaking!

Haven't you posted this before?

[propellerhead]

Crazy!

I wonder why they don't just used sand bags for weight then just release them when they want to head up again.

[black50]

That's quite breathtaking!

Yeah, its a repost, but still cool

Yeah? Lol oh well. I was re-fascinated by it then

[Snatch Napkin]

It's certainly a worthy repost!!

[347Mike]

I think I will pass. I don't travel down places I can't see, unless it has lips or buried treasure.
