Product Overview

The Atomic Aquatics M1 Octopus shares the second-stage design of the M1 primary regulator, including features developed for cold-water and rough-water diving.

A thermal heat sink supports heat transfer at the second stage, while the surge-protected front cover and super-dry exhaust valve help manage water movement around the regulator. Automatic Flow Control and a Rapid Adjustment Knob provide automatic airflow control alongside manual breathing-resistance adjustment.

The yellow front detailing distinguishes the octopus from your primary regulator.
