About Mares Prestige 12S Regulator

Excellent performance without a high price, incorporating all the features that make Mares regulators stand out from the rest Mares Prestige 12S is a compact regulator with stylish design, strengthened by the ultimate technologies to provide steady, natural and effortless breathing.

The first stage is a balanced diaphragm design in a chromed marine grade brass body with the Tri-material Valve. The "Tri-material" valve is a patented innovation, conceived and created to optimize performance, safety, and reliability over time for Mares MRT first stages. During operation, the high-pressure valve is subjected to various stresses. In traditional valves, these stresses, combined with extreme usage conditions, can cause premature wear of the valve with a consequent drop in reliability, performance, and safety. After careful study of the forces involved, the pressures that act on the surfaces of the valve, and the usage conditions to which it is subjected, Mares has created the new "Tri-material" valve (brass, soft polyurethane, and "heavy duty" polyurethane), found today on all Mares MRT first stages.

This innovative technical solution guarantees maximum performance, safety, and durability for Mares first stages. The exclusive MARES DFC system featured minimizes the intermediate pressure drop which occurs in all regulators during the inhalation phase. This pressure drop is greater when higher airflow is demanded of the regulator. The DFC system substantially reduces breathing effort and inhalation resistance, especially during deep dives and under high air flow conditions.

The second stage 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 second stage cover features the new "mesh-grid" system for water inflow and outflow, which provides a further performance improvement. Furthermore, the compact and ergonomic exhaust tee ensures superior hydrodynamic performance and reduced exhalation resistance. Mares Prestige second stage incorporates the Fluid Dynamic Deflector, developed after in-depth studies and tests of fluid dynamics, 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.

Mares developed the Super flex 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 reducing jaw fatigue. Superflex hose is 3/8" Threaded hose and is 31.5" (80 cm) in length. Mares Prestige 12S comes with a limited lifetime warranty.

      Comments about Mares Prestige 12S Regulator:

      I used this regulator for my last 10 dives and, overall, a I find it very good. The ease of breathing, at any depth, is amazing. The extra flex hose is good but at times I found it pulling on the second stage. The mouth piece is comfortable and jaw fatigue was not an issue for me.

          I bought this reg and used it on my very first open water dive last weekend
          It was fabulous! My jaw was not tired after use and I loved the bubbles coming out the side, not up in front of my mask every time I breathed

              I tried this regulator recently and I like it a lot. Compared to the regulators I used when I was taking my open water course this one is much better!. I also like that it has 4 low pressure ports and 2 high pressure ports, I will take advantage of this once I get a computer.

                  Great REG, thats all I can say, I ran my tank down to 150 psi, and could not even tale. My first breath was the same as my last, twelve dives with this reg and I'm totally satisified..
                  No jaw fatigue, which is common for me, easy to set up.
