I'd hand it over to them if they was any closer but its about a 2 hour drive so best thing for me is to post it unless i can find a company that do it closer to homeH-pac are still doing event air, they have one of my bottles to test currently as it happens.
Most dive centers are likely to be able to arrange a test too if you can find one locally, just saves on the old postage.
Im based at North Lincolnshire, I stopped paintball for a couple of year and wanting to get back into it again, my tank ran out late last year. I used to take it to fatbobs but they don't do it anymore which is like a 30 minute drive for me luckily, they recommended me HPAC, i was just hoping someone knew somewhere to where im based.Whereabouts are you based, what events do you play at, is there an IDEST test centre any where near you, if there is they should be able to do it, when you last had it tested which company did it, it'll be on the test label stuck on the bottle.
