The 62X membrane first stage is small and very performing in cold waters. The finish is chrome with a "pearl" effect surface. Equipped with the AST system, it protects against the ingress of water into the first stage. The 62X first stage breaks records as the smallest first stage in the diving market: it measures 63mm high and weighs just 464g (DIN). This small but powerful diaphragm first stage is 10% smaller and lighter than its 52X predecessor and has 30% less volume.
Equipped with Auto Sealing (AST) technology that protects against the ingress of water in the first stage. The central parts of the 62X have been redesigned to generate an even better seal, making it an excellent regulator for cold water diving. The addition of the optional Twin Balanced Piston (TBP) makes this one of the best performing regulators in cold water. The finish is chrome with a "pearl" effect surface. Technical innovations specific to the inner workings of this first phase include a new shutter seat that is now sharper with a smaller cone radius and a reduced angle to better define the sealing surface.
