Air balanced piston first stage in a chrome-plated body delivers consistent and effortless airflow, regardless of depth, tank pressure, or breathing rate.
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.
- 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.
