French_guy,

I understand your concern about using a hand pump with an L5-S1 injury. The first gun I suggested only requires 2000 PSI, which is much easier to pump than the more typical 3000 PSI, and even the 4500 PSI some PCP rifles require.

The tank "minutes" refers to how long a firefighter can breath with tank air. It all scales directly with volume. I have a 90 Cu Inch tank. It operates at 4500 PSI, and has a regulator which drops the output to 3000 PSI. Two of my PCP guns are 3000 PSI, one is 2000 PSI. If you start with a 3000 PSI scuba tank, your airgun only gets to 3000 PSI on the first fill. Each subsequent fill give you a little less pressure from the scuba tank, until it is refilled. So, I prefer a 4500 PSI tank, it can give the full 3000 PSI for multiple fills. Once my tank is down to 3000 tank pressure, it is time to refill it, as nobody wants to go to the range, or the woods to hunt with a partially filled airgun.
