Mares Ultra regulator is made from ultralight techno polymer, offering high air flow and a Twin Power system. When combined with the great 72X first stage, it is ideal for all tech and recreational diving configurations! 72X's pre-oriented pressure ports provide for an ideal placement of hoses even when using two independent regulators.
The all pearl finish chrome plated marine brass 1st 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 1st 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 72X first stage is also equipped with AST 1st stage dry system.
The Ultra 72X 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 Loop 72X first stage guarantees a stable flow of air, even under extreme conditions. The first stage is equipped with 8 LP ports with 3/8", four vertical and four radial and 2 HP 7/16" ports for attachment of a pressure gauge or air integrated console.
The Mares Ultra Second Stage includes Mares' Twin Power system and, made from techno polymer, it is lightweight. The Mares Ultra Second Stage Regulator 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. The octopus has a wide pivoting purge button for easy access. 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 hose is a 3/8" threaded high flow design and is 29.5" (75 cm) in length. The regulators total weight including the hose is 42.6 oz. (1,208g).
