Atomic M1 Octopus

Atomic M1 Octopus

The M1 safe second is factory rated for oxygen-enriched mixtures up to 80%. 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. The critical metal components of the demand valve are all made of Titanium or 316 Stainless Steel and are completely corrosion proof. The front cover is designed to limit sensitivity to currents and swift moving water.


Most manufacturers produce just an “economy” and a “performance” octopus model. Yet, even their high-end octo cannot come close to matching the performance of the Atomic family of safe seconds. Each Atomic octopus is designed and precision-built to perform as perfectly as its primary model counterpart.
All Atomic second stage primary models are available as dedicated safe seconds with high visibility yellow covers and an extra-long 36" hose.
