SCUBAPRO MK25 EVO/S600

  • The high performance MK25/S600 has long been known for its low work of breathing and tremendous reserve capacity. Year after year, in successive independent tests, it has consistently ranked as one of the top-performing regs on the market.

    1st stage: Since its release in 2004 the MK25’s quickly made it to the very top of piston design regulators. It is very durable, reliable and delivers extra-high and effortless airflow, regardless of depth, tank pressure or breathing rate. Since 2016 the MK25 benefits from another substantial upgrade, SCUBAPRO's patented Extended Thermal Insulating System (XTIS), giving the reg its new name: MK25 EVO. The system let’s you enjoy all the advantages of an MK25 - regardless of how cold the water is! The XTIS makes this possible by fully isolating the mechanical elements of the first stage from the cold, increasing its freezing resistance 30 percent over the - already very freezing resistant - prior MK25 without compromising breathing performance. The key insulation system components are visible in blue.

    New spring insulating coating, body insulating bushing, anti-freeze cap, bigger body and cap thread all work in concert with the XTIS to improve cold-water performance.

    The MK25 EVO features a swivel turret with five high-flow LP ports (high flow ports deliver about 15 percent more air than conventional low pressure ports) for optimal hose routing. It also has an external intermediate pressure adjustment that allows technicians to maintain peak performance without the need for disassembly.

    2nd stage: the S600 features a precision molded carbon fiber/technopolymer housing and interior full metal valve housing (barrel). This is an air-balanced 2nd stage that delivers effortless inhalation and exhalation. The S600 has efficient user controls that include a powerful purge, an inhalation effort control knob and Venturi Initiated Vacuum Assist (VIVA) dive/pre-dive switch.

    Now you can spice up your MK25 EVO/S600 system with interchangeable S600 purge covers in a choice of colors (Blue, White, Yellow, Red and Pink). Pick a color that celebrates your diving style!
