I can't remember if I've already posted in this thread and won't take the time to read all of it.
When I was gathering footage for a future episode on "deep ecology," I routinely dive to a basement depth of 200 ft on air. However, I did so after about two months of conditioning myself at deeper and deeper depths to assess my response to narcosis. I was quite functional at my maximum depth... able to locate, frame and smoothly follow subjects while I videotaped.
However, I would not classify any of those dives as "bounce" dives. They were often in the 50-60 min duration range, involving a number of deep stops and long stays in the shallows (10-20 ft). Our submarine profiles off Catalina's leeward side allow us to do such dives with ease by simply following the slope back up.
I do NOT recommend deep air dives (or solo diving) to any other diver since I do not know their capabilities, training or response to emergency situations.
