All of VA Scuba's tanks from Cyl-Tec include a Pro Din/Yoke Valve with current Hydro.
Tech Diver Direct/Virginia Scuba recently teamed up with Cyl-Tech to make aluminum 72s. We've found these make for great bailout bottles on a rebreather, or stage bottles on doubles due to their size and buoyancy qualities.
We recently did the buoyancy testing with them.....


With a regulator on (who uses a tank without a regulator?) they are neutrally buoyant with 500psi!
Thanks to Mark for taking the time to get the details of the tanks out for us!
