(CitiCorp), Santa Monica Lines: 29 Summary: Keywords:Stainless Steel Scuba Cylinders < munch! gobble! chomp! chew! Why don't "THEY" fix this bug? > I have seen those tanks that Walt referred to. Yes they are a smaller size than a regular steel 74.2, and yes they do hold 80 cu ft @ 6000psi _BUT_ most places that vend air can pump (MAYBE..) to 4500. Most boats have only 2000psi available. This is the reason I purchased a Scubapro steel 96. The rated cubic displacement is @ 2640psi (that's counting 2400psi working + 10% overfill which is allowed for the 1st five-years!) With a 2000psi fill the tank is about 83 cu ft, or so I've been told...maybe I should check this with some of that fancy math stuff! (-| The buoyancy factor is -6lbs full/-3lbs empty by my testing. It seems to be a nice tank. It only cost $275, and while the that's close to the cost of a Justin Stainless (of Chanute, Kan) Tank the practical use of a scuba must take into account the available pumping pressures. One other point-98% of the regulator 1st stages are only rated to 3000psi. If you try to use your regulator with >3000psi, the yoke will let-go! If the industry goes to 6000psi, I think I'm gonna setup an NC 5-axis to manufacture 6000psi rated replacement yokes/1st stage cases!!! -Avatar-> Erik K. Sorgatz Transaction Technology Inc.
