- Delivery & Returns
The Scubapro MK25 S600 is a truly tried and tested regulator that has been around in one version or another for many years and is used by thousands of divers all over the world. This version marries the high performance balanced piston MK25 EVO first stage with the latest cosmetic version of the balanced S600 second stage.
The MK25 EVO is Scubapro's thoroughbred race horse. Years of careful breeding has led to this seriously high performance version of the MK25 and features new anti-freeze coatings and components to further improve it's cold water performance and reliability. The MK25 EVO is fitted with two high pressure ports on either side on the main body and five high-flow low pressure ports mounted on a swivelling turret.
The S600 is a compact balanced second stage with a lightweight but strong fibreglass body that features diver adjustable inhalation control and venturi switch to fine-tuning during the dive. The S600 has a large purge button set in the centre of a stainless steel front cover, an orthodontic mouthpiece and compact exhaust cover.

MK25 EVO First Stage:
- Air balanced flow-through piston in a chrome-plated brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
- Patented XTIS (Extended Thermal Insulating System) fully isolates the mechanical elements from the cold, increasing freezing resistance 30 percent over the previous MK25 without compromising breathing performance. 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.
- Anti-freeze protection radically 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.
- Five high-flow low pressure ports on a swivel turret maximize hose routing options.
- External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
- Available in either 3364psi/232bar INT or 4350psi/300bar DIN configurations.
- Weight: INT 232 (oz/g): 27.9/790; DIN 300 (oz/g): 20.1/572.
