The Mares Fusion Octopus features the Twin Power System, VAD and VAD +, allowing the diver to control air flow without compromising breathing effort. Maximum performance, even in cold water!
For extreme demanding conditions, such as use in cold or contaminated water, the Mares Fusion Octopus second-stage is also made of satin chrome plated brass. This material offers a number of benefits: ruggedness and thinner walls which allow compact dimensions obtained without using smaller-diameter diaphragms; this result in reduced water drag. The second stage ha an anti-freeze function, which is enhanced by the "radiator action" of the metal. The Mares 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 Mares Fusion Octopus 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. Superflex hose is 3/8" Threaded High Flow hose and is 29.5" (75cm) in length. The regulators total weight is 40.95oz (1,161g) Mares Fusion Octopus comes with a comprehensive owner's manual and a limited lifetime warranty.
Mares Fusion Octopus Special Features:
All Metal Technology - Outstanding mechanical reliability and high thermal conductivity make our metal 2nd stages extremely long lasting and ideal for cold water dives. The high thermal conductivity of metal reduces also the dry mouth feeling during the dive.
(VAD) Vortex Assisted Design - The air bypass tube delivers air to the mouthpiece creating a swirling vortex with a low pressure area in the center that keeps the diaphragm down during inhalation, for very sensitive and easy breathing at all depths.
Superflex Hose - Extreme light weight and exceptional softness guarantee the maximum freedom of movement.
Twin Power - New, flow control manages the delivery rate of your gas, from natural breathing to power breathing. The former is the traditional way of breathing a Mares regulator, (VAD) while the latter (VAD+) provides an extra push when you need it.
