SCUBAPRO MK25 Evo / S600 Dive Regulator System combines an air-balanced first stage with an air-balanced second stage to deliver steady airflow with low work of breathing across a range of diving conditions. It provides reliable, consistent air delivery for scuba and underwater exploration, supporting comfortable breathing and dependable gear performance in varied water temperatures and depths.

Built for durability and precise control, the MK25 Evo first stage uses chrome-plated brass with Extended Thermal Insulating System (XTIS) to improve cold-water resistance and delay ice formation, while anti-freeze protection enhances breathing reliability in extreme temperatures. The S600 second stage features a rugged technopolymer housing with a stainless steel frame, a diver-adjustable inhalation effort knob, and a Venturi-Initiated Vacuum Assist (VIVA) switch. The system offers flexible hose routing via a swivel turret with four high-flow and one axial high-flow low-pressure ports, plus two opposing high-pressure ports for up or down orientation. External intermediate pressure adjustment enables quick tuning in the field, and the DIN connector type ensures compatibility with compatible scuba gear.
