Extreme diving makes having an extraordinary Octopus even more important. The Atomic 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.

Add a super-wide exhaust deflector and an exclusive Atomic engraved heat-protecting jam nut for freeze protection to cover almost any extreme diving situation.
