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 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.
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 M1 Octopus Diaphragm is made from High Quality Silicone Rubber. This Pneumatically-Balanced Poppet Second-Stage has Atomics 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 Atomics 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" (91.4 cm) 3/8" Threaded Low Pressure (LP) Hose. The Regulator is also equipped with a Dual Silicone Comfort Fit Mouthpiece with Tear-Resistant Bite Tabs, weighs 13.8 oz (391 g) with the Hose and is covered by a Limited Lifetime Warranty.
This product has a limited warranty of 24 months.

Comments about Atomic M1 Octopus, Yellow:
Wish I'd gotten the standard second stage vice the octopus. This is a great breather and prefer it over my B2.
