The G3 Pressure Measuring Device (PMD) is once again, a groundbreaking original design from the engineers at Dangerous Power. The PMD for the G3 allows the paintball enthusiast to monitor air pressure, guard against air spikes, 'creep' or loss of pressure commonly experienced during paintball play. The unique design of the G3, the first of its kind, is the only design that allows the utilization of a rear gauge in this manner.
