Description

The Atomic Aquatics M1 Octopus is a high-visibility Safe Second designed to pair with the M1 primary for reliable performance in demanding underwater environments. Built for extreme diving, it serves as a dependable backup in cave diving, cold water, and rough seas, ensuring your scuba gear has a trusted secondary option.

Long-hose reliability meets practical visibility with a 36-inch hose and a neon-yellow front cover, making it easier to locate and reach in underwater situations. The M1 OCTO shares core M1 technology, including Automatic Flow Control and a Titanium Seat Saving Dynamic Orifice, while remaining compatible with higher oxygen mixes when established guidelines are followed.

Features

36" hose and neon-yellow front cover — long hose length and high-visibility design enhance positioning and recognition during underwater dives.
High-performance valve body — Zirconium plated brass demand valve with a heat sink for fast thermal transfer and reduced freezing in cold water.
Automatic Flow Control (AFC) — patented AFC with a Rapid Adjustment Knob allows manual tuning in special diving situations, improving breathing stability.
Titanium Seat Saving Dynamic Orifice — minimizes wear on the low-pressure seat to extend service intervals and boost reliability.
Thermal management — thermal heat sink designed to minimize freezing risk in cold-water diving environments.
Exhaust and front-cover protection — super-dry exhaust valve and surge-protected front cover perform reliably in rough water and high-current scenarios.
Comfort and mobility — patented Comfort Swivel provides approximately 30° range of motion without hose binding, pulling, or kinking during underwater maneuvers.
Underwater compatibility — designed for scuba gear and diving setups that require a dependable backup octopus, with compatibility for higher oxygen mixes when guidelines are followed.

Specifications

M1 MONEL OCTO

A SAFE SECOND FOR HIGHER O2 MIXTURES

If you are diving with a primary specified for higher EAN mixtures, you need a Safe Second to match. Atomic M1 OCTO parts used throughout the second stage are identical to the M1 primary model. The M1 OCTO is factory-ready for EAN mixtures up to 50% or Oxygen mixes up to 80% when special guidelines are followed.

ATOMIC PRIMARY FEATURES BUILT INTO A SAFE SECOND

Just like our primary second stages, Atomic divers can expect the patented AFC Automatic Flow Control and Titanium Seat Saving Dynamic Orifice. Just like the M1 primary, the M1 OCTO includes a thermal heat sink for cold water, and a super-dry exhaust valve for rough water. The biggest difference is the high-visibility Neon Yellow surge-protected front cover and an extra-long 36” hose.

PATENTED COMFORT SWIVEL

Divers also shouldn’t have to worry about turning, twisting or looking over your shoulder. The popular Atomic Comfort Swivel removes that concern by allowing 30° range of motion without hose binding, pulling or kinking. The B2 Comfort Swivel is polished Stainless Steel with black PVD coating. (US Patent No. 7,188,869)
