I have my original 2 scubapro steel tanks for sale . They have a working pressure of 3000psi and carry up to date VIP and Hydros. They originally carried a '+' stamp and when filled to 3300 psi, they were rated as 95 CF cylinders. The current hydro does not include a '+', so at 3000psi, they hold ~86 cf. I am asking 300 dollars for the pair. Thanks for looking .
