OK, so I am considering getting my own tanks sometime before the next dive season. I understand most the advantages and disadvantages of the steel and a luminum. The one thing I haven't quite got a grasp on is the volume vs. pressure thing. Am I correct in thinking that if you have a steel tanks filled to capicity (I am thinking something like 2650...if my memory serves me correctly) and a aluminum tank of equal volume fill to capacity at 3000psi then the amount pf air in either tank is the same right? In other words 80 cu. ft. @ 2650 is the same as 80 cu. ft. @ 3000 and should last an equal amount of time. Do I have things straight or am I totally confused?
