My tanks are XS Scuba... Worthington Cylinders (Galvanized LP Steel 2400 psi.) with a 10 mil thick zinc hot dip galvanizing to protect against the corrosive ocean environment.
Gotcha, underwater photography is awesome. I shoot to put fish in the freezer. If I could rig a camera to my gun, to take frame shots of the shaft launch, flight and impact.............. Seriously I have seen some real cool things underwater, it's a totally different world.
