The tables were cut using decom.  This is an easy to use program that allows
surface o2, air, nitrox, heliox and trimix.  I also own Dr. X and Diveplan,
Decom is the easiest to use for predive gas planning and is inexpensive (my
opinion only).

I recently began using surface o2 to improve my diving efficiency at work.
While doing u/w log recovery in the 40' to 85' range, we were pulling 5 very
hard dives per day averaging approx. an hour per dive.  We would do about 5
minutes of deco at the end of each dive.  We were working 5 days per week
and had a working day of approx. 14hours/day with non diving time being
spent tending and humping gear.  At the end of each day we were a sad sorry
bunch divers with a great deal of general fatigue, but no clinical dci.  As
our work progressed we were forced to dive progressivly deeper to recover
wood in quantity.  In order to minimize the chance of an expensive dci
episode we began using 100%o2 for 45 minutes via demand reg after each dive.
The subjective difference was amazing!  We were working deeper and harder
and yet were able to do far more work and finished our days feeling like we
had put in a hard day but without the degree of post dive fatigue and mental
cloudiness we had previously experienced.  On approximately the 12th  day of
this I had a hit in my right shoulder that was resolved within about 20
minutes after going on to o2.  Needless to say all of  this made a believer
out of me.

Unfortunately with my sport diving I do not have the services of a 10 T
bottle bank of o2 and a working barge and crane to carry all of this ####.
An o2 rebreather would seem to be the ideal combination of portabliety and
gas duration.  People have been making these for years ( as was illustrated
again in the latest  Aquacorpse) so some one out there must have the info on
how to construct a scrubber.

Thanks Bill
