Oops.
First time we had twins on our backs we pointed out to the instructor that at twice the SAC rate the twins don't really offer a lot more TIME under water :-) By now my SAC rate with twins in cold water is only about 10-15% higher than in with an AL80 in warm water... > > Can a statement that gas incompressibility at high pressure is considered > > when calculating gas consumption be added to the manual so other > > ill-informed divers, like me, don't get confused? > > It might be a good idea.

Tomaz, could we do this in the dive list? /D _______________________________________________ subsurface mailing list [email protected] http://lists.hohndel.org/cgi-bin/mailman/listinfo/subsurface
