The APEXS ATX40 uses the DS4 first stage. Unique over-balanced, diaphragm design - as the diver descends, the over-balancing feature allows the medium pressure gas in the hose to increase at a rate faster than ambient. This results in superior performance at depth. An environmental dry system keeps water out of the main spring chamber thus preventing ice build-up and keeping silt and contamination out. The chromed marine brass first stage has four medium-pressure (3/8" UNF) ports and one high-pressure port (7/16" UNF). "
