We used AL80's and my starting pressure was just over 3000PSI.

ClevelandDiver:FYI - posting this strictly to answer the original question, not as a suggestion of what is realistically or safely attainable for the average diver.
Bret Gilliam did a bounce dive on air to 452 feet using a single 100cf tank in 1989. He trained very intensively for over a year to prepare himself, including at least 100 dives over 300 feet deep. Obviously VERY dangerous and not recommended for anyone without massive amounts of training and a full support team. I believe this one of the deepest single tank dives anyone has actually done.
Diver Dennis:On June 12th I did a bounce dive to 207' with a commercial diver friend.
MikeC:ClevelandDiver, I remember an article back around '94-'96 that involved Mr. Gilliam again where he and a group of other divers, maybe five divers, did a deep air dive to around that depth. The writer of the article, one of the divers, told of trying to slow his descent by grabbing the descent line, actually a cable, and getting fish hooks in his hands. I wish I remember which publication it was.
Diver0001:Mark Andrews did one to 513ft. Damned psycho. He'll be the next one going for the deep trimix record.
