SCUBAPRO MK25 EVO/S600

The MK25 EVO first stage lets you enjoy ultra-fast breathing response, instant delivery of air on demand, great sensitivity, and extra-high airflow - no matter how cold the water. This is made possible with SCUBAPRO's exclusive patented Extended Thermal Insulating System (XTIS) that completely isolates the first-stage mechanical element from freezing, 30 percent of its freezing over previous versions of the MK25 without compromising breathing performance. Increases resistance.

This makes the MK25 EVO the ultimate do-it-all first stage for all water temperatures. The S600, with its rugged fiberglass casing and stainless steel front face and ring, provides smooth user control while providing efficient user control including a powerful purge, a breathing effort control knob and a Venturi initiated vacuum assist (VIVA) dive / pre-dive switch. Easy breath in and breath out.

Features:

Double chrome-plated body

High air flow rate:> 8500 l / min at 200 bar

Coldwater - anti-freeze protection using XTIS technology

Metal valve housing (barrel) is capable of withstanding years of aggressive diving

The air-balanced valve smoothes the breath effort when diving at different depths and supply pressures.

Technical Information:

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): 20.1/570.

Airflow at 2900psi/200bar: (l/min/SCFM): >8500/301.

Intermediate pressure (psi/bar): 133-142/9.2-9.8.

S600 Second Stage:

Metal valve housing (barrel) is able to withstand years of aggressive diving.

Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.

User controls include a diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch.

Super-flow hose features an oversized bore (larger inside hose diameter) that allows more air to flow on each inhalation.

The ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn't inhibit airflow.

Weight (without mouthpiece): 7.1oz/200g.

Airflow at 2900psi/200bar: 1850 l/min - 66 SCFM.

Interchangeable purge covers allow you to make your regulator truly unique.

Available purge cover colors: Blue, White, Yellow, Red, Pink.
