Among the first things beginning divers learn is that gas consumption increases at depth. For example, a cylinder that would last a diver 50 minutes at the surface may only last ten minutes at 40 mi>. That’s not a lot of time when there is so much water over your head. Because of this significant increase in gas consumption, deep divers need to be able to determine, ahead od time, whether or not they will have suficient breathing gas.
