The MK25 EVO first stage lets you enjoy an ultra-fast breathing response, instant delivery of air on demand, great sensitivity and extra-high airflow -- regardless of how cold the water is. This is made possible with SCUBAPRO's exclusive patented Extended Thermal Insulating System (XTIS) that fully isolates the mechanical elements of the first stage from the cold, increasing its freezing resistance 30 percent over previous versions of the MK25 without compromising breathing performance. This makes the MK25 EVO the ultimate do-it-all first stage for all water temperatures.

First Stage MK25 EVO

• 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 by 30% and delaying ice formation in extreme cold-water conditions without compromising breathing performance. Key insulation system components are visible in blue
• Spring insulating coating, body insulating bushing, anti-freeze cap, bigger body and cap thread all work in concert with the XTIS to improve cold-water 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 maximise hose routing options
• External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily
• Available in either 232bar INT or 300bar DIN configurations
• DIN version comes with a dual-compound wheel that features an ergo shape and softgrip on a rugged black nylon frame
• Airflow at 200bar: >8500 l/min
• Intermediate pressure: 9.0-9.8 bar
