The Atomic M1 regulator provides extreme performance without compromise. Designed to withstand almost any diving conditions, the Atomic M1 is ideal for cold water diving or for travel. Built on the world acclaimed T2 and B2 regulator platforms, the M1 first stage uses chrome plated brass for the body and Monel alloy for the key internal components. The first stage is also factory sealed to prevent contamination and freeze up. The M1 second stage features a thermal heat sink as well as an anti-surge front cover for use in high current situations to eliminate possibility of free flow due to water action on the diaphragm.
