OVERVIEW
With the MK25 EVO/A700 you are guaranteed a reliable, low-effort delivery of air, no matter how hard youre breathing, how deep youre diving, or what your temperature gauge reads. 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. The A700 second stage, with its metal casing, screw-down cover, metal valve housing (barrel) and over-molded accents, exhibits a real muscularity in design. Put them together and you get unparalleled breathing performance whether youre cruising the balmy waters of the tropics or venturing beneath a polar ice cap.

-Air balanced piston first stage in a chrome-plated body delivers consistent and effortless airflow, regardless of 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.

-Rugged full metal second stage case and valve housing (barrel) are able to withstand years of aggressive diving.

-Metal second stage case construction enables the use of a larger diaphragm inside a compact casing, increasing breathing sensitivity.

-Air balanced second stage valve smoothes out the inhalation effort when diving at varying depths and supply pressures.

-Sectional exhaust tee and a first-rate purge help to deliver effortless inhalation and an ease of exhalation that is unmatched.
