The Mares Fusion 52X Regulator is comprised of the compact top performer MR52X First Stage, all the features of the proven MR52 first stage and more, making it the best for a unique high caliber set up. 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.
