What's in the box: 1st Stage, 2nd Stage and LP Hose
The Prestige 22 Diaphragm First Stage features the DFC System and a replaceable HP seat connector. 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 high pressure poppet was designed for a "2 year or 200 dives" service interval; double the high pressure seat life standard! Compact body, in a modern and smart style, it is made of hot-forged nickel-plating and chromed brass. It is fitted with a preferential 1/2" intermediate pressure port for connection to the primary second stage, plus 3 other standard 3/8" LP ports and 2 HP ports with 7/16" UNF thread. The latter are inclined at a 45° angle to allow a more ergonomic layout of hoses.
The Prestige 22 Second Stage Regulator is equipped with Mares Dive Pre-Dive System (DPD). The DPD allows the diver to set the regulator second stage to be less sensitive when jumping in the water off a boat or while surface swimming through surf or current. Once the diver is ready to descend they can enhance toe regulators breathability with a simple twist of the switch.
The Prestige 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 second stage cover features the new "mesh-grid" system for water inflow and outflow, which provides a further performance improvement.
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.
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. 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. Superflex hose is 1/2" Threaded High Flow hose and is 29.5" (75 cm) in length. Mares Prestige 22 DPD weighs 40.7 oz (1,154 g) and comes with a limited lifetime warranty.
