Scubapro Regulator MK25EVO/S620TI

First Stage

• Air-balanced flow-through piston housed in a chrome-plated marine-grade brass body, delivering constant and effortless airflow regardless of depth, tank pressure, or breathing rate.

• Patented XTIS (Extended Thermal Insulating System) thermally insulates the internal 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 components are highlighted in blue.

• Spring insulating coating, body insulating bushing, anti-freeze cap, larger body and cap thread all work together with the XTIS to enhance cold-water performance.

• Anti-freeze protection significantly increases breathing reliability when diving in extremely cold water temperatures.

• Two opposing high-pressure ports allow the first stage to be positioned either upward or downward.

• Four high-flow low-pressure ports and one axial super high-flow low-pressure 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 features a dual-compound handwheel with an ergonomic shape and soft grip mounted on a rugged black nylon frame.

• Intermediate pressure: 9.2 – 9.8 bar

• Weight: INT 232 – 790 g | DIN 300 – 570 g

Second Stage

• Air-balanced valve smooths inhalation effort at varying depths and supply pressures.

• Rugged reinforced technopolymer case and front cover are designed to withstand years of aggressive diving.

• Titanium barrel is rugged, corrosion-resistant, and lightweight for long-term reliability.

• Uses the S600’s large diaphragm inside a compact casing for maximum breathing sensitivity.

• Diaphragm fits inside a more compact housing to further enhance breathing responsiveness.

• User controls include an easy-grip diver-adjustable inhalation effort knob and VIVA (Venturi-Initiated Vacuum Assist) lever.

• The exhaust tee increases performance while directing bubbles out of the diver’s field of view.

• Compact Hi-Flow mouthpiece improves airflow and comfort, fitting all mouth sizes.

• Super-flow hose with an oversized bore allows more air to flow with each inhalation.

• CE certified according to the latest EN250A European Standards, suitable for all diving conditions, including extreme cold water.

• Weight (without mouthpiece): 179 g
