The Mares Dual ADJ regulator is ultralight with adjustable breathing comfort. All this combined with the 52X, a first stage including a tri-material valve for the utmost reliability and safety, and dual DFC ports for the very best performance! The Mares Dual ADJ 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. Dual ADJ 52X represents a radical departure from any existing regulator. The Dual ADJ 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 MR52X's pre-oriented pressure ports provide for an ideal placement of hoses even when using two independent regulators.
The all pearl chrome plated finished marine brass first stage regulator is a balanced diaphragm design which is environmentally sealed. The diaphragm membrane transmits the pressure changes to the internal mechanism eliminating the need for the surrounding water to enter the intricate mechanism. The benefit of this type of first stage design is that none of the internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance.
The MR52X 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.
Another unique feature of the first-stage is the dynamic flow control (DFC). The DFC system minimizes the intermediate pressure drop during inhalation. The 52X first stage guarantees a stable flow of air, even under extreme conditions. The first stage is equipped with 4 LP ports with 3/8" and 2 HP 7/16" ports for attachment of a pressure gauge or air integrated console.
