Subject: Re: deep air diving
Well, there is the obvious that we all problably recognize, Steve, but
the most insidious is the 120 to 170 zone where you really can't "feel"
much impairment, and that is where the unexplained accidents seem to
occur. In our diving, it is where the stupid stuff happens, so we do not
do it at all. 

Narcosis is like boiling a frog - if you put the frog in some water,
turn on the stove, and bring up the heat, he might sit there until
boiled. On the other hand, if you tried throwing him into a pot of
boiling water , he would jump out. You take a hit of air at 200+ after
being on gas, you will feel it a couple of minutes later very vividly.
If you go dwon to 200+ on air, you may not not. When you get into the
big numbers, you don't really care.

Given my choice, I always dive mix, even at 100 feet, but in the
Project, we deco on nitrox 35% from 120 up, but we have gas on our
backs, and we have come up from the deep stops on another trimix. We do
not allow air diving anymore. I personally will not dive with anyone
diving air - I don't have to.

There is nothing to be learned form impaired diving, and really deep air
diving is nothing more than drug abuse -just look at the players there.
The dive training organizations are full of dopes who think there is
some ability to do this, or some machoism associated with it. There are
some very, very, very stupid people in diving instruction. We are not
talking Harvard Business School graduates, we are talking work at the
Seven Eleven or teach diving assholes.

Keep in mind also, Steve, that the many "deep air" courses require
little or no money to teach, but if you can require them, you can make a
nice profit. Hopefully, we get a few of these deaths to bite some ass,
and we get the insurance companies to quit insuring it.
