the make guges like this, the needle just pushes a red one up with it, that stays when the pressure falls, then can be reset. I dont know were to get it though. You could just do this though:

<pre>
Chamber>check valve>tee>guage
^
Ball Valve

just use a one way check valve and a normal air pressure gauge. you hook the one way valve to the chamber. to that you hook a T fitting. one end has a blow gun to reliese the perssure you just made, and on the other end of the T fitting you put your gauge. this way when you fire the gun, the one way valve lets air into your gauge but then traps the pressure there when the spud leaves the barrel and the pressure drops. this way you can look at the pressure gauge all day and it will still read the same pressure. teh blow gun is to release the pressure so the gauge goes back to 0. this is what i use on my hybrid

go to a auto place and get a compresion tester it is made to do this $7 to 15 bucks it will go up and stay and when you push a shrader valve it releses the presure good luck.
