Compact, reliable, and performance are the key words for describing this new Mares first stage. Featuring the DFC system, it meets all divers' demands at any depth. The new valve guarantees longevity and advanced performance. A medium-size second stage is made of ultra-light techno-polymer. The large purge button is effortless to use while wearing gloves. The VAD system delivers excellent and natural breathing at any depth. The super-flex hose is light and flexible for maximum comfort.
The chrome plated marine brass first stage regulator is a balanced diaphragm design which is inherently 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 Prestige15X 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 Prestige15X 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.
The second stage Vortex Assist Design (V.A.D.) 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 second stage cover features the new "mesh-grid" system for water inflow and outflow, which provides a further performance improvement. The compact and ergonomic exhaust tee ensures superior hydrodynamic performance and reduced exhalation resistance. Mares Prestige second stage incorporates the Fluid Dynamic Deflector, which is engineered to receive and properly direct the airflow from the bypass tube to the mouthpiece. Combined with the VAD system it delivers very natural and effortless breathing. All enclosed in a lightweight Techno-Polymer housing. Regulator has the super flex hose. Hose is extremely light weight and exceptionally soft, guaranteeing the maximum freedom of movement and reducing jaw fatigue. Super flex hose has 3/8" Threads and is 31.5" (80 cm) in length. The regulator weighs 34 oz. (965 g).
