The Atomic Aquatics M1 2nd Stage with a 32-inch hose in Gray is a balanced linear flow regulator stage designed for easy breathing during scuba diving across a wide range of depths and conditions. It is optimized for cold-water diving with a thermal heat sink and an improved super-dry exhaust valve.

Designed for underwater gear reliability, this second stage emphasizes smooth breathing, consistent performance, and long-term durability in demanding environments.

For flexible underwater setups, the 32-inch hose extends reach while preserving maneuverability and comfort during dives.
