I wonder why they don't have a small flotation bag which inflates automatically if a sensor doesn't detect movement for 15 seconds, or some predetermined time which is considered reasonable.
It wouldn't need to rocket you up fast. Just something to initiate a gradual ascent.
It would need a pressure of about 600 psi plus to be functional at 1200 feet.
That sort of pressure could be supplied by the air tank.

Sad story for all concerned.

deep

How do these dives work ?. Does the support divers go down first at various stages and wait for the main dive to ascend ? or does the main diver go down first and the support divers aid his return ?

that would kill u



watch this - Austtralian story. about a guy who died trying to retrieve another dead diver in a cave.
I can't feel too sad about these guys. what they are doing is stupidly dangerous and for nothing other (at least the guy int e the OP topic) other than breaking a record. you can do it in a sub with much less danger if you have a passion for exploring the depths..
what got me about the asutralian story video above is how easily he died. He got slightly tangled in a bit of rope, and was breathing a bit heavy. Because of the extreme depths the act of just breathing slightly heavier killed him. He had shears but couldn't manage to even coordinate the cut of the line. I watched another video on the same dive and the guy said right at the start of the tangle and he begins to breathe a a bit heavier - he said from that point he was a dead man, and he could never survive, just from breathing a bit heavier. And he said that Dave would have known that too. It just seems so pointless.

My scuba diving knowledge (or lack there of) has long since left me but the forum/blog Galah posted gives a great rundown on the sheer lunacy of it all.

Sad story of a man pushing the limits ! pweedas You cant just go to the surface at that depth mate !
I personally don't think rectec divers have any reason to go that deep.


Support divers would of gone down in a bell?
So what happened He ran into trouble on the way down past 300` exceeded his saturation ?

Technology will make tanks redundant !

yeajh i did some reading. technology made tanks redundant years and years ago for those depths. you can go to those depths not a problem if you need to, and many people do with the right gear. but to try with scuba (tanks) and deco is kinda madness because you have to carry so much gas (and constantly vary the gas mix) and do it so fast that you get severe physiological complications that will most likely kill you. there's just no point. there are sat divers on that forum saying that he was always going to die, and for nothing because you can dive there no probs with other technologies. stupid example of human nature.

I suspect that big suit ^^ wouldn't have fit through the narrow gap at the beginning of his fatal dive, he would have had to use tanks. Can't imagine diving with seven tanks being much fun. I don't see the point of it either, but each to their own. At least he managed to return the body of the diver that went before him...

No the most recent guy subject of the op died in the ocean.
They guy in the cave died trying to retrieve the other dead guy.
You don't need a suit like that. That's basically a sub for amatuers. They can do without that

The cave diving is pretty interesting by going deeper into the caves archaeologists are finding and carbon dating animal remains
Human remains and analyzing stalagmites stagagtites Beacuse they are virtually untouched

last half hours worth a flick thru !

My mistake, and I looked at both links.

OP dive guy was pushing his luck in making a leap from his last deep dive of 800ish to his next (and fatal) of 1200 ft. Too big a jump obviously. I still don't see the point of it. I never liked deco stops, never felt more like shark bait than when hanging about on the anchor rope. Imagine the hours you'd need to hang about when diving that deep.

My ears and sinus won't let me go past 3 meters.....385. Wow.
