Nitrox Requirement

[DiveCaptDean]

40% and less is exactly that...recreational...

I personally feel the direction of diving is definitely headding in that direction.  I think its a good idea..but i think the agencies would have to do some modifications to their over all plan outlines....because technically your first certification is to 60ft why not throw the use of nitrox in there...it would only be adding a safety factor to the dive....in basic terms..let them know that rather that not being able to exceed the 130 recreational limits, they cannot exceed 80ft because of the standard mix in their tank...

i think that rebreathers are so much on the rise that they will in time..be the preferred means of diving...becasue they are based on nitrox at a minimum" scr" and O2 and perfect ppo2 for "ccr"  why not have ocr head in that direction now...
