CO2 Injection System

Pictured left is the CO2 Injection System that I use. It's mainly a 5 lb CO2 tank made from high grade rust resistant aluminum with a dual gauge heavy duty regulator with electronic solenoid and needle valve (accurate to +/- 5 bubbles/min).

It costs me about $12 US to fill the tank. That is a little expensive for 5 lb of CO2, but I got to keep my canister. Many places have a tank rotation where you bring in your nice new shinny tank and they give you back a rusty old crap tank. I don't like places that do a tank rotation. I'm willing to pay a little more and keep my new tank.
