Atomic Aquatics designed the M1 Regulator for challenging specialty dives. Both technical and recreational divers who face cold water or strong currents can rely on the M1. It's based on the design of the award-winning B2 and T2 regulators. It adds new features but keeps the ones you know and love, like the Atomatic Flow Control and ergonomic second stage design. That lets you take Atomic's smooth breathing performance to new depths and extremes.

The M1 also features a thermal heat sink and a super-dry exhaust valve that are ideal for cold water diving. The super-wide exhaust deflector disperses bubbles for improved visibility.

Built Rugged from Elite Metals

The M1's first stage body is durable chrome-plated brass. However, the internal components of the M1's first stage are made of Monel. This alloy blended from nickel and 6 other metals can survive in extreme conditions. It resists corrosion from rapidly flowing seawater, oxygen, chemicals, and extreme heat or cold. It's factory sealed to resist contamination and freezing. The second stage is made from titanium, 316 stainless steel, and multi-layer zirconium coated brass. The Valve Body is zirconium nickel over brass and the Seat Saving Orifice is stainless steel.
