Air wasn't even mentioned in my Fundies class.

Well that shows the inconsistencies in GUE training. Who was your instructor?

From both of my DIR-F courses and my RecTriox course, the standard recreational gasses were as follows:

Air - 60'
32% - 60' to 100'
30/30 - 80' to 120'

Jason, what's the logic behind using air down to 60' but not down to 100'? I was under the impression that 32% Nitrox was recommended for all dives above 100' when available.

What benefit would someone get using 32% at 60ft?

Jeff, JJ goes over the advantages and disadvantages of nitrox in his book, check it out if you need a refresher. I'm just wondering why those advantages would be prefered over the disadvantages between 60'-100' but not above 60'.

i've used 21% on a dive to 70 ft and gotten out and felt like crap later. haven't had any dives where i've gotten out and felt like crap after i just started diving 32% or 30/30 all the time. i'm on the 'air is for tires' side of the debate based on experience. YMMV.

I think you need to rethrink that, Lamont. My tires are filled with nitrogen. It is supposed to be a far superior mix.
