yeah yeah I understand cascading and just wanted to know your bottles were at least 3000psi rated.
FYI the 9oz tank on the jacpaq is rated for 1800 psi - not that I'll be putting air in it...
THAT'S what I was getting at ...3000 into 1800 is dangerous if you're not 100% sure how to do it. There's 2 Combat Dive Teams on Base, I used to run one of them and a good friend ran the other until 2 weeks ago when he was posted, but I may still know some of the guys there. old friends = free fills providing yer jugs are good for hydro/visual.
