Balanced-piston first stages are the first choice of demanding deep sport divers and professionals. First stages with air-balanced pistons deliver significantly more air to the second stage than any other first stage, while their performance is totally unaffected by changing tank pressure and depth. A balanced piston allows the use of lighter and more sensitive components, resulting in an ultra-fast breathing response, instant delivery of air on demand, and extra-high airflow, especially in low tank pressure ranges.
SCUBAPRO leads the way in piston-controlled first stages. The MK25 is the perfect example, bringing you ultra-stable intermediate pressure which ensures an instant and constant delivery of ultra-high airflow. You can count on incomparable performance for all diving conditions and at any depth. Made of chrome-plated, marine-grade brass, the MK25 will be your diving partner for a lifetime.
MK25 EVO First Stage:
Air balanced flow-through piston in a chrome-plated brass body provides constant and effortless airflow un- affected by depth, tank pressure, or breathing rate.
Patent pending XTIS (Extended thermal Insulating system) fully insulates the inner mechanism from the environment, improving cold-water resistance by 30% and delaying ice formation in extreme cold-water conditions without com- promising 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 a 3364psi/232bar INT configuration.
Weight: INT 232 (oz/g): 27.9/790.
Airflow at 2900psi/200bar: (l/min/ SCFM): >8500/301.
Intermediate pressure (psi/bar): 130-142/9.0-9.8.

SCUBAPRO MK25 EVO First Stage 01:31
The latest regulator innovation from SCUBAPRO is the patent-pending Extended Thermal Insulating System (XTIS), ushering in a new era of cold water protection for the industry. Available in EVO first stages, XTIS fully insulates the inner mechanical components for extra protection. With XTIS, the cold-water protection rating for the MK25 EVO increases 30 percent over its predecessor. http://www.scubapro.com/en-US/USA/regulators/products/mk25-evos600.aspx
