Description
Offering effortless air delivery and outstanding reliability, this is the go-to air delivery system for cold water or technical diving. There’s no better example of solid first stage performance in all water temperatures than the MK25 EVO. Teamed with the venerable G260, this system can be relied upon to deliver top-of-the-line performance in the most extreme conditions.
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.
G260 2nd Stage
The Scubapro G260 2nd Stage is a tough and reliable 2nd stage preferred by many divers for its cold water performance and ambidextrous design. Air balanced the G260 has metal internal components and a consistent performance.
- Air balanced second stage valve smooths out the inhalation effort at varying depths and supply pressures.
- Rugged reinforced technopolymer design features Scubapro’s largest second stage casing and diaphragm for the ultimate in breathing sensitivity, regardless of position in the water.
- Metal components (inlet tube, orifice, inhalation control knob and hose connector) increase resistance to freezing when diving in extreme conditions.
- A diver-adjustable inhalation effort knob fine-tunes air delivery to suit changing depths, water conditions and personal tastes, and a Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch prevents free flows in cold water or when used as an octopus.
- High-flow exhaust valve reduces exhalation for better overall breathing comfort, and the reversible hose attachment allows you to easily adjust hose routing for tech diving configurations.
- Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn’t inhibit airflow.
- LP hoses: 20cm (x2), 64cm (x1), 200cm (x1)
