Amazes me how anyone could consider 220ft on a single 80 cuft tank with perhaps 20 dives under their belt a safe dive!!!

I'm just glad ScubaBoard wasn't around when Jacques Cousteau was getting started. After reading a couple of the threads on here he may have given up on his ideas, inventions, and explorations once he realized he could die on almost any dive and everything he was probably doing was against the "rules".
I would imagine there are plenty of old bold divers. They just don't hang out on ScubaBoard.
Didnt Jacques lose a son that way?
On 28 June 1979, while the Calypso was on an expedition to Portugal, his second son, Philippe, his preferred and designated successor and with whom he had co-produced all his films since 1969, died in a PBY Catalina flying boat crash in the Tagus river near Lisbon. Cousteau was deeply affected. He called his then eldest son, the architect Jean-Michel Cousteau, to his side. This collaboration lasted 14 years.
Didnt Jacques lose a son that way? I imagine he wouldve loved the opportunity to do that particular dive over, armed with the knowledge we have now.
From your previous posts, Im guessing you have no technical, or even professional level (not that thats a substitute) training, and if you do, you obviously didnt learn even the basics of safe deep diving.
I hope your diving isnt as reckless as your statements on this thread.
We have all done stupid dives,
and certainly dont encourage others to try.
That kind of attitude on a boat Im working will earn you a nice dry bench for the duration of the trip.
I was sitting at a table of beginner and newly acquired advanced level divers (they were rewarded their advanced cards at dinner) the instructor told one of the divers it would be fine to drop down to 220 and come right back up…
What are the issues here especially if the diver is pretty overweight and out of shape…
I clearly never said it was safe. It's all relative, a dive like this can be dangerous, very dangerous, or even foolhardy depending on all of the variables involved.
I have 122 dives over 100 feet but only 10 over 130 feet. My maximum depth of 153 feet was with a pony and a very good buddy with a pony under the ideal conditions I stated above on a site we had dived several times before. We considered the dive relatively dangerous, planned it carefully and executed it according to plan. I'd have to have a very good reason to diver deeper than this and would have to accept the inherent risk prior to planning such a dive.
Good diving, Craig
Lets, see. My planner software estimates a 1 minute dive to 220ft on air would require 38cf per person assuming 8 minutes of stops and 1cf/min per person on the surface. So it looks like an AL 80 (77cf) is not really enough, and no where near what you should have. Hope for a overfill and don't put air in your BC (I guess that would help you get down to 220.) Then again, don't do it and wait for a set of doubles, trimix, and deco stages along with appropriate training.
