For extreme demanding conditions, such as use in cold or contaminated water, the Fusion Octopus second-stage regulator is made of satin chrome plated brass. This material offers many benefits: ruggedness and thinner walls which allow compact dimensions obtained without using smaller-diameter diaphragms; this result in reduced water drag. The second stage has an anti-freeze function, which is enhanced by the radiator action of the metal. The Fusion Octopus with its vortex assist design (V.A.D.) system: all Mares second stages offer the unique patented VAD system. The air bypass tube conveys air to the mouthpiece creating a swirling vortex with a low-pressure area in the center this keeps the diaphragm down during inhalation, giving very sensitive and easy breathing at all depths. The bypass has undergone a true transformation: 77% increase in flow cross section and double curvature to provide a smoother flow while optimizing performance. For the first time, a Mares second stage regulator is equipped with a flow control (Twin Power), managing the delivery rate of gas from natural breathing to power breathing. By rotating the adjustment sleeve on the hose inlet, you can achieve VAD+ performance.

Furthermore, the compact and ergonomic exhaust tee ensures superior hydrodynamic performance and reduced exhalation resistance. The mouthpiece is made of soft hypoallergenic silicone: limiting jaw fatigue and offering a secure fit even after very long dives. Mares developed the Superflex hose after many years of testing and research. The results achieved far surpassed the tests required by EN250. Hose is extremely light weight and exceptionally soft, guaranteeing the maximum freedom of movement and further reducing jaw fatigue. The regulator comes with a high visibility yellow cover and Superflex hose that is a 3/8" threaded high flow hose and is 39.4" (100 cm) in length. The regulators total weight is 17 oz. (481 g).
