Atomic M1 Monel Octo Review - $350.00 - Scuba Gear Customer Reviews

I bought it with first regulator and major second regulator. This Octo also can reach 80% oxygen range.

Wish I'd gotten the standard second stage vice the octopus. This is a great breather and prefer it over my B2.

Octopus

By JOSEPH H.

Great Octopus

Most manufacturers produce just an economy and a performance octopus model. Yet, even their high-end octopus cannot come close to matching the performance of the Atomic Aquatics safe seconds. Each Atomic Aquatics 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.

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.

The Atomic Aquatics M1 Octopus diaphragm is made from high-quality silicone rubber. This pneumatically balanced poppet second stage has Atomic Aquatics patented seat saving dynamic orifice which unlike most second stage orifices is a floating valve design which reduces wear on the second stage poppet seat when the regulator is not pressurized adding life to this important seal.

The M1 second stage regulator is equipped with Atomic Aquatics patented Automatic Flow Control (AFC). This unique diaphragm activated vain automatically controls the flow and Venturi effect of the second stage for optimum breathing resistance at all depths. The second stage does have a rapid adjustment knob for manual second stage de-tuning in rare special situations. The M1 Octopus has a bright yellow front cover for easy identification in an out-of-air-emergency and a 36" (91.4cm) 3/8" threaded low-pressure (LP) hose. The regulator is also equipped with a dual silicone comfort fit mouthpiece with tear resistant bite tabs and weighs 13.8 oz. (391 g) with the hose.
