MK25 EVO / S600 Dive Regulator System

Product Description

The SCUBAPRO MK25 EVO / S600 regulator system combines SCUBAPRO’s top-performing piston first stage with one of the most respected second stages in diving. Known for its exceptionally low work of breathing, this regulator combination has consistently ranked among the best-performing regulator systems available.

The MK25 EVO first stage features an air-balanced flow-through piston design in a chrome-plated brass body, delivering instant air delivery, high airflow, and outstanding breathing sensitivity regardless of depth, tank pressure, or breathing rate. The patented XTIS (Extended Thermal Insulating System) enhances cold-water performance by thermally insulating the internal mechanism and delaying ice formation. Combined with advanced anti-freeze protection, the regulator remains reliable even in extreme water temperatures.

The S600 second stage provides smooth inhalation and effortless exhalation thanks to its air-balanced valve, metal valve housing, and reinforced technopolymer casing with stainless steel frame. Diver controls include a powerful purge button, adjustable inhalation effort knob, and Venturi-Initiated Vacuum Assist (VIVA) switch.

A super-flow hose with oversized internal diameter increases airflow, while the orthodontic mouthpiece ensures long-lasting comfort during extended dives. Together, the MK25 EVO and S600 deliver dependable breathing performance in warm, temperate, and cold water conditions.
