hoosier:So, get your own air source with your buddies and forget it.
spectrum:I agree that is a tempting thought. The cost per fill alone does not justify it. When you factor in the runaround, hassles and independence it's appealing.

hoosier:Within 15 min filling time, I think shop 2 is more likely correct figure without considering a wet fill. The depreciation in pressure is more than 200 psi based on my experience. I am sick and tired of leaving my tanks, arguing a right fill, and paying more because it is a high pressure. So, get your own air source with your buddies and forget it.
UB:I beach dive Venice (FL West Coast) and West Palm Area (FL East Coast). These are both ~3hr drives for me so I try and make a day of it with two dives.
Thanks for the feedback - I do know that the Shop with the larger loss in pressure uses banks and I am not sure of the other shop.
wedivebc:That is not actually true. The first law of thermodynamics is heat can not be created or destroyed. There is not heat generated when transferring gas from one container to another other than the heat picked up from the piping and valves between the source and the destination container. Ever notice as you tranfer from a bank it gets cooler? There is more heat from compressed air because usually ambient air has more heat energy than compressed air that has been allowed to cool off for a period of time.
