Scubapro Regulator MK25EVO/S600

First Stage

• Air-balanced flow-through piston in a chrome-plated marine-grade brass body, providing constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
• The patented XTIS (Extended Thermal Insulating System) thermally insulates the inner mechanism from the environment, improving cold-water resistance by 30% and delaying ice formation in extreme cold-water conditions without compromising breathing performance. Key insulation system components are visible in blue.
• The spring insulating coating, body insulating bushing, anti-freeze cap, larger body and reinforced cap thread all work together with the XTIS to enhance cold-water performance.
• Anti-freeze protection significantly increases breathing reliability when diving in the most extreme water temperatures.
• Two opposing high-pressure ports allow the first stage to be positioned either up or down.
• Four high-flow low-pressure ports and one axial super high-flow port on a swivel turret maximize hose routing options.
• External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
• The DIN version comes with a dual-compound wheel featuring an ergonomic shape and soft grip on a rugged black nylon frame.
• Airflow at 200 bar: >8500 l/min
• Intermediate pressure: 9.2–9.8 bar
• Weight: INT 232 790 g; DIN 300 570 g

Second Stage

• The air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
• The metal valve housing (barrel) is built to withstand years of intensive diving.
• User controls include a diver-adjustable inhalation effort knob and a Venturi Initiated Vacuum Assist (VIVA) dive/pre-dive switch.
• The super-flow hose features an oversized bore, allowing more air to flow with each inhalation.
• The ultra-comfortable orthodontic mouthpiece is easy to grip without restricting airflow.
• CE certified according to the latest EN250A European Standards for all diving conditions, including extreme cold water.
• Weight (without mouthpiece): 200 g
