Air Balanced, Flow-Thru-Piston- First Stages with air balanced pistons deliver significantly more air to the second stage than any other first stage, while their performance is totally unaffected by the changing tank pressure. A balanced piston allows the use of lighter and more sensitive components, resulting in ultra fast breathing response, instant delivery of air on demand, and extra high air flow, especially in low tank pressure ranges. The tired diver benefits from a smoother breathing regulator during the ascent or deco stop. Balanced piston first stages are the first choice of demanding sport divers and professionals. A balanced piston performs equally in warm and cold water environments.

MK25 EVO/A700 Diving Regulator System
Discover the peace of exploring the water with the SCUBAPRO MK25 EVO/A700 combo, which combines the high-performance MK25 EVO first stage with the A700 second stage to create a premium regulator system.
The MK25 EVO first stage with an air-balanced piston offers excellent resistance to freezing and superb inhalation sensitivity. The full-metal A700 combines excellent breathing performance with a real muscularity in design.
The Benefits of Piston Technology
The task of a first stage regulator is quite simple: reduce the high-pressure air ﬂowing from the tank to a consistent intermediate pressure for delivery to the second stage. The best way to accomplish this necessary step-down process is with an air-balanced piston-style first stage, the first choice of demanding sport divers and professionals.
An air-balanced piston first stage like the MK25 EVO offers excellent reliability thanks to fewer moving parts, and is more responsive for instant delivery of air on demand and extra-high air flow—especially in low tank pressure ranges.
Air-Balanced Flow-Through Piston MK25 EVO First Stage
The MK25 EVO first stage provides instant delivery of air on demand in all diving environments and all water temperatures. The inner mechanism is insulated from the environment, improving cold-water resistance and delaying ice formation.
The opposing HP ports allow the MK25 EVO to be positioned either up or down. The five high-flow LP ports provide higher airflow than standard low-pressure ports and are mounted on a swivel turret to maximize hose routing options.
A700 Second Stage: Muscular Design, Unparalleled Breathing Performance
With its striking all-metal casing, screw-down casing cover, and metal valve housing, the precision hand-crafted A700 second stage features air-balanced valve technology, a stainless steel inlet tube, and an oversized exhaust valve that deliver an unmatched ease of inhalation and exhalation.
Able to withstand years of aggressive diving, the rugged, full-metal A700 second stage case construction enables the use of a larger diaphragm inside a compact casing, increasing breathing sensitivity. The air-balanced second stage 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 Venturi-Initiated Vacuum Assist (VIVA) switch.
