Would appreciate the buoyancy [fresh or sea water] of my '57 set of Navy triple tanks with 500 psi.

Thanks...Phil
 
Phil,

I have never used the triple 40 cubic foot tanks, but I have seen them in photos. I think they are about neutral in the water at 500 psig. But, you can tell us about it when you get them wet. ;)

Thanks John....best info so far is -6 full [2,220+ psi] and -1 at 500 psi...but you are absolutely correct, in water eval is what really counts to achieve correct buoyancy.....
 
44's right? I have a set of Rene's.
Corks.

In a one piece 5mm in SW I need 14lbs. Never actually read them when low, but after using reserve (750psi) I am still neutral with a quicker up and down swing. No air cell of course.

I would love to put a twin set together with these tanks.
