DINfor cold water

For compact comfortable breathing performance in cold or silty water, the MK17 EVO 2/S620 Ti regulator system simply can’t be beat. 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. Small and lightweight, the S620 Ti delivers excellent performance providing effortless airflow under all dive conditions. 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. S620Ti second stage's air balanced valve smooths out the inhalation effort at varying depths and supply pressures. Rugged reinforced technopolymer case and front cover with stainless steel frame looks good plus is able to withstand years of aggressive diving.
