You'll see this item at paintball fields and pro shops nation wide. Chances are, if you and your paintball buddies play consistently on your own field, you'll have likely purchased a bulk CO2 tank to fill your paintball tanks. If not, you should think about it, Hustle Paintball can take care of that for you as well.
To correctly fill a CO2 paintball tank, you need to go through a mildly complex process of cooling, bleeding, refilling, etc. When you're finished, to correctly gauge how full the tank is, you need to weigh it. What better way than a digital gauge that is specifically designed to hold paintball tanks? This style of gauge has a light chain and hook to hold your tank. Simply hang up the Digital Fill Gauge on a handy tree limb, or your dumb buddy's earlobe, then hang the tank below it, and you're set.
