: : I am new to Paintball and need a few questions answered. 1. I have a 20oz. Catalina Co2 Tank and want to put a gauge on it to monitor it while I play. How much PSI does that type of tank hold? Do I get a gauge that goes from 0-300PSI, 0-500PSI? : 0-1000 PSI should do the trick. No, a 1000 PSI gauge is inadequate. C02 can easily get to 1800 PSI, at which point your burst disk should go (don't believe me? Leave a full tank in your car in the summer). A 1000 PSI gauge could easily be wrecked - use a 2k or more if you are going to put a gauge in it. BUT, a gauge is pretty much useless on a CO2 system - all it will really tell you is when the tank is almost dead empty, otherwise the pressure will read 750 PSI (or close, at room temperature) as long as you have any liquid in the tank. As soon as you flash off the last of the liquid, the pressure will drop very rapidly. If you are desperate to have a gauge in your system, install a regulator with a gauge behind it. That at least will tell you some usefull information, namely what your gun's operating pressure is and would help you set your velocity.
