    Default High Pressure Aluminum

    Can anyone fill me in on some information I need? I recently picked up 4 used aluminum tanks for cheap. They are made by Catalina circa 2008. Stamped as C74 with a service pressure from the factory of 3442. Obviously I know they are 74's at that pressure. But, does anyone know the buoyancy characteristics of them? It is not listed anywhere including catalinas website. They are slightly taller than a Worthington 100 and slightly shorter than a PST 100. I haven't taped them yet but they are definitely inches shorter than a standard 80.

    I found over on scubaboard that they were imported from Australia as left overs and sold by Genesis state side. They do have genesis valves.

    Hang them on a fishing scale underwater (just the tanks, not the scale).

    It may be moot. If there'a no DOT stamp it would be illegal to fill them in the states.

    Unless, of course, you have your own compressor.
