Fusion 52X represents a radical departure from any existing regulator. The Fusion 52X incorporates a double DFC system that provides a consistent flow of air at any depth, even when breathing simultaneously from both the primary second stage and the octopus. The natural convection channel (NCC) system and the design of the Abyss Second Stage with more metal on the front cover, allows this combination to achieve very high performance in cold water. The NCC System increases cold water performance by creating a flow of water across the regulator. The flow is driven by the change of density in water with temperature. The Abyss 52’s pre-oriented pressure ports provide for an ideal placement of hoses even when using two independent regulators.
The Abyss 52X uses A.C.T. Advanced Coating Technology. This patented technology created to optimize performance, safety and reliability. The valve is covered with a hard Polyurethane (PU) and the sealing surface is a layered with a soft PU for a perfect seal. Tri-material (brass, soft PU and heavy-duty” PU) reaches new levels of durability. The new valve is 600% more durable than its predecessor.
For extreme demanding conditions, such as use in cold or contaminated water, the Fusion 52X second-stage regulator 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 Fusion 52X 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. Superflex hose is 3/8″ Threaded High Flow hose and is 29.5″ (75cm) in length. The regulators total weight is 41 oz. (1,161 g).
