Scubapro MK 25 Evo / S600 Dive Regulator System (DIN)

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.

• Air-balanced flow-through piston in a chrome plated brass body provides constant airflow unaffected by depth, tank pressure, or breathing rate, supporting smooth scuba and diving performance.
• XTIS (Extended Thermal Insulating System) thermally insulates the inner mechanism from the environment, improving cold-water resistance and delaying ice formation in underwater conditions.
• Anti-freeze protection increases breathing reliability in extreme water temperatures during scuba diving.
• Two opposing high-pressure ports allow the first stage to be positioned up or down, providing flexible setup for underwater gear.
• Four high-flow and one axial super high-flow low-pressure ports on a swivel turret maximize hose routing options for your diving configuration.
• External intermediate pressure adjustment enables quick tuning by technicians for consistent performance at depth.
• Air-balanced second stage valve smooths inhalation effort at varying depths and supply pressures.
• Second stage’s rugged technopolymer case with stainless steel frame offers durability and a modern look for scuba gear.
• Metal valve housing (barrel) is built to withstand years of aggressive diving.
• User controls include a diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) switch for dive/pre-dive adjustments.
• Super-flow hose with an oversized bore delivers more air per inhalation for efficient underwater breathing.
• Orthodontic mouthpiece provides comfort and easy grip without inhibiting airflow during long dives.
