Impeccable reliability, even in extremely cold water
The Abyss (MR22) 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 intermediate pressure port for connection to the primary second stage, plus 3 other 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. For extreme demanding conditions, such as use in cold or contaminated water, the Abyss Extreme firststage is equipped with the Cold Water Diving kit (CWD) which completely seals off all first stage internal components from contact with the water.
