It was painted white, but a tank is a tank is a tank as far as the way they look. There was no scubapro lettering on it. I'll check next week when I go out again.

Thought of one more question last night. Do you remember what the starting pressure was for the full tank?

Wow you're awfully concerned about what tank I was using, eh?

It started at ~3000psi

Not LP, but not HP.

I'm just bored.

It was almost certainly a SP steel 72. A good fill should be 3300 psi to get a full 71.4 cf, so you had a bit of a short fill.

Hehe...yeah, and the 300psi I wasted on a freeflow on the surface probably didn't help my bottom time, eh? I stuck the second stage in my BC pocket on the surface to keep from getting sand in/on it...when I got in the water, I aparently hit the purge button. oops.

Just call me newbie.
