ScubaPro MK17 EVO2 Regulator

The new MK17 EVO 2 is a sealed diaphragm first stage with a dry chamber based on a twin spring layout and two HP ports at 15-degree angle to make hose routing easier. Sealed balanced diaphragm design makes for the ultimate compact first stage for cold water or contaminated diving conditions. Air-balanced diaphragm delivers consistent and effortless airflow, regardless of depth, tank pressure, or breathing rate. Dry chamber is completely environmentally sealed with a dual diaphragm system that keeps out contaminated water. The rib is designed to enhance heat exchange, making the first stage cold water-proof. Two opposing high-pressure ports positioned on a 15º angle allow the first stage to be positioned either up or down, plus provide an optimal hose/transmitter layout.
