THE PERFECT OCTO FOR EXTREME CONDITIONS

Extreme diving makes having an extraordinary Octopus even more important. The Atomic Aquatics M1 OCTO is a Safe Second that performs equal to its M1 primary dive buddy. Cave diving, cold water, and rough water conditions demand backup systems divers can count on when needed. The M1 OCTO delivers confidence in extreme situations.

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 Aquatics 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 AQUATICS PRIMARY FEATURES BUILT INTO A SAFE SECOND

Just like our primary second stages, Atomic Aquatics 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.

The M1 Safe Second is factory rated for EAN mixtures up to 80% Oxygen. The demand valve body is Zirconium plated brass for fast thermal transfer with a heat sink feature to reduce the possibility of freezing in cold water.
