PST Steel Tank

[akscubaduck1]

I just received a PST 3AA 3000 psi tank (free, the best kind)
Very good shape, pasted Hydro!
I've inspected and filled quite a few.
Now that I have this tank I would like to know capacity and buoyancy characteristics.
Original hydro date 7 77+.

Can't say I have ever seen a 3AA 3000 psi tank from that era. How about a picture

I have 2 of them. They are heavy! Definitely negative empty or full. I believe that it something like a 92 cf at 3000. I actually really like diving them. But they are boat anchors.

I Don't have a pic, but it could be mistaken for a steel 72cf.

Thank you Dave. That's kinda what I figured.
I'd love to find another one to band up as doubles or side mount.
Dove it Wednesday while raising a 27' boat in Whittier, AK.
A bad brake for the owner. The boat only had 6 hours on it.
Just glad that it sunk there and not out in the sound.

They might be 96's. My former employer's husband had a pair that match the rest of your description.

Hold on to it. That is the best 12 liter, 6.9, steel tank ever made. The capacity is 94.6 cf @ 3300 psi. The balance and buoyancy characteristics are great for diving suited up. Not as great for skinning it but that is what BC's are for. IMO, too heavy for doubles.

duck are you still around?
I've got one of those PST tanks too, bought new around '85. IIRC it was sold as a "96.2" and that would be at the + rating. If you find a competent hydro shop, they can be tested for a + rating and stamped again for it forever--according to the DOT.
Compared to an Alu80, you can take about 8-9# of lead off your belt.

A modern Faber HP will be lighter, but these old ones are bomb-proof.

I bought one a couple years ago. Most of the information is not really visible. But I believe it’s similar to the tank you’re talking about. Thoughts?
