Artikel omschrijving Apeks Ds4 1St Stage
The Apeks DS4 first stage has a 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 buildup and keeping silt and contamination out.
