Questions and Answers for Atomic M1 Monel Octo:

  • Mark:

    What is the difference between the m1 reg and the m1 octo is the tuning different. I bought 2 m1 Regs from you guys to do tech diving but never really started so now that I am starting to try to do more teaching i wanted to convert one of my M1 Grey regs to get the yellow kit and use as my octo.

    Same second stage. Typically detuned slightly and of course the color.

Why A Family Of Octos?

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. So when you need it, you know exactly what to expect.

All Atomic Octopus models come with a standard extra-long 36” hose. Custom length hoses are available.

Cloning Can Be A Good Thing
An Atomic octopus reduces stress in emergency situations
In an emergency, why would you or your buddy breathe from an inferior regulator? An octopus should breathe easy. All Atomic second stage primary models are available as dedicated safe seconds with high visibility yellow covers and an extra-long 36' hose.

M1 Octo
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.
