Hey, I will soon need to get a hydro test for my air tank, and idea where I can get one? I live in Kent and it can't be too far away. Also, are they free? or how much do you pay?
Hpac is an option, but you may be able to get it tested through a local dive shop when they get dive bottles tested. Not all can offer the service but some can. Search, or look in Yellow pages for your local ones and give them a call.
