ScubaPro MK25 EVO/S620Ti Regulator

This is the ScubaPro MK25 EVO/S620Ti Scuba Diving Regulator Features: Air balanced flow-through piston in a chrome plated brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate. Patented XTIS (Extended thermal Insulating system) thermally insulates the inner mechanism from the environment, improving cold-water resistance and delaying ice formation in extreme cold-water conditions without compromising breathing performance. Anti-freeze protection radically increases breathing reliability when diving in the most extreme water temperatures. Two opposing high pressure ports allow the first stage to be positioned either up or down. Four high-flow and one axial super high-flow low pressure ports on a swivel turret maximize hose routing options. External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily. Air balanced second stage valve smoothes out the inhalation effort at varying depths and supply pressures. Second stage's 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. User controls include an easy-grip diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) lever. Newly designed Compact Hi-Flow mouthpiece, exclusive to the S620 Ti, is mounted on an enlarged mouthpiece pipe to improve airflow as well as mouth comfort. SCUBAPRO teams its high performance first stage with its new air balanced second stage. The MK25 EVO offers excellent resistance to freezing, superb inhalation sensitivity and instant delivery of air on demand. The new S620 Ti embraces the best features of SCUBAPRO's renowned S600 in an upgraded, state-of-the-art design. Smaller and lighter than the S600 but using the same-sized diaphragm, the S620 Ti delivers effortless airflow under all dive conditions. The full titanium inlet tube is ultralight, the large purge button improves water circulation, and the new exhaust tee increases performance while directing bubbles out of the field of view. In all water temperatures, in all dive conditions, this new reg system is a winner. "
