A steady flow of air, whatever the depth, temperature or workload
SCUBAPRO pairs its best-selling air-balanced second stage, the S600, with the MK25 EVO, which it calls its top-performing air-balanced piston first stage. SCUBAPRO says the combo is well known for its low work of breathing and has ranked year after year among the top-performing regulator systems on the market. The MK25 EVO gives an ultra-fast breathing response, instant air on demand, great sensitivity and impressive airflow. The S600 gives smooth, easy inhalation and exhalation, with a powerful purge, an inhalation effort knob and VIVA. Together they keep the air flowing steadily whatever your depth, the water temperature or your workload. Choose INT or DIN 300.

The MK25 EVO first stage uses an air-balanced flow-through piston in a chrome-plated brass body. SCUBAPRO says it gives an ultra-fast breathing response, instant delivery of air on demand, great sensitivity and impressive airflow. It has two opposing HP ports and five LP ports on a swivel turret (four high-flow, one axial super high-flow).
The MK25 EVO first stage carries SCUBAPRO's patented XTIS (Extended Thermal Insulating System) and anti-freeze protection, and SCUBAPRO says the system keeps a steady flow of air whatever the water temperature.
The S600 is, according to SCUBAPRO, its best-selling air-balanced second stage, with smooth and easy inhalation and exhalation. The case and front cover are reinforced technopolymer with a stainless steel frame, and the valve housing (barrel) is metal.
The inhalation effort knob lets you adjust the breathing yourself, alongside the VIVA (Venturi-Initiated Vacuum Assist) dive/pre-dive switch and a purge SCUBAPRO calls powerful. The super-flow hose has a larger inside diameter, and the mouthpiece is orthodontic.
The first stage clamps onto the tank valve. The main photo on this page shows this version.

The first stage screws straight into the tank valve.

It is how the first stage connects to the tank valve, so match the valves you dive with. INT (yoke) clamps onto the valve; DIN 300 screws straight into it. Not sure? Ask us on LINE.
