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 smoothes 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.
• Full titanium barrel is rugged, anti-corrosion and lightweight for long-term reliability.
• Large diaphragm fits inside a more compact second stage casing for maximum breathing sensitivity.
