Scubapro MK25 EVO/A700 Dive Regulator System

Scubapro MK25 EVO/A700 Regulator

With the MK25 EVO/A700 you are guaranteed a reliable, low-effort delivery of air, no matter how hard you're breathing, how deep you're 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 you're cruising the balmy waters of the tropics or venturing beneath a polar ice cap.

SCUBAPRO Technology

MK25 Evo First Stage

• 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.

A700 Second Stage

• 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.

The MK25 EVO and A700 combo from Scubapro offers an ultra-high airflow system for peak performance in all diving conditions. As a leader in piston-controlled first stages, Scubapro's MK25 EVO boasts patented features for consistent, reliable performance. The balanced piston first stage ensures stable intermediate pressure, providing instant and constant high air delivery, no matter the tank pressure or water temperature.

Air-balanced pistons deliver more air to the second stage and maintain performance even with changing tank pressure. Their design allows for lighter, more sensitive components, resulting in ultra-fast breathing response and high airflow, particularly in low tank pressure ranges. Ideal for demanding sport divers and professionals, the MK25 EVO offers two opposite high-pressure ports (HP) for optimal gauge positioning and five high-flow low-pressure ports (LP) on a swiveling turret for 360-degree hose swivel.

Scubapro's Extended Thermal Insulating System (XTIS) ensures reliable performance in extreme cold water conditions. With a 30% increase in freezing resistance over the previous model, the MK25 EVO meets EN250-2014 requirements for cold water diving. Design features such as a thermal insulating coating on internal components, encapsulating main spring bushing, and patented finned cap optimize cold water performance.

The A700 second stage is the pinnacle of Scubapro's regulator line, offering extraordinary breathing performance in a handcrafted, full metal design. The compact, air-balanced valve technology ensures minimal inhalation effort and a high-flow exhaust valve for ease of breathing in any diving situation. It also features a diver-adjustable inhalation knob and Venturi Initiated Vacuum Assist (VIVA) for personalized breathing control and free-flow prevention.

The MK25/A700 regulator comes with a 3/8" threaded super-flow hose, a high-flow mouthpiece, and a read-first manual. Weighing 38.4 oz (1,090g), this regulator is designed for comfortable, effortless underwater breathing and lasting dive experiences.
