Scubapro MK25 EVO/A700 Regulator

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 without compromising breathing performance.

The A700 second stage offers extraordinary breathing performance, including effortless inhalation and an ease of exhalation that is unmatched, all in a precision-handcrafted, full-metal package.  Its air-balanced valve technology and oversized exhaust valve work in conjunction with a well designed sectional exhaust tee, a first-rate purge and responsive user controls to create a bullet-proof breather with effortless inhalation and an ease of exhalation that is unmatched.

FIRST STAGE:

• 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.
• Five 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.

SECOND STAGE:

• Rugged full metal case and valve housing (barrel) are able to withstand years of aggressive diving.
• Metal construction enables the use of a larger diaphragm inside a compact casing, increasing breathing sensitivity.
• Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
• User controls include a diver-adjustable inhalation effort knob and coaxial-flow Venturi-Initiated Vacuum Assist (VIVA) lever.
• Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
• Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow.
