First stage
Constructed from chrome-plated brass with integrated heat-exchange ribs and a ribbed diaphragm clamp, the first stage effectively manages thermal conditions. Its over‑balanced diaphragm ensures that medium pressure increases at a greater rate than ambient pressure as depth increases, delivering consistent breathing ease at depth. The Auto Closure Device (ACD) limits water ingress during cylinder changes. Ports include five medium‑pressure and two angled high‑pressure outlets, with a double‑swivel hose connection facilitating ergonomic hose orientation for single‑tank or sidemount layouts.

Second stage
Equipped with a venturi lever and a large breathing-effort adjuster designed for gloved use, the second stage also features a laminar-flow valve to smooth inhalation, a two-stage progressive purge, and reversible hose port orientation. The Diver Changeable Exhaust (DCE) system lets divers switch between small and large exhaust tees, both supplied. The heat exchanger in the second stage moderates cold‑gas discomfort, while the Comfo‑bite mouthpiece reduces jaw fatigue. Nylon braided flexi‑hose enhances cold‑water durability and flexibility 

The EVX200 is tailored for divers who require robust performance in demanding environments. It meets the needs of those diving in cold conditions or advancing into technical configurations, offering practical innovations rather than cosmetic updates.
