MK25 EVO / G260 BLACKTECH
MK25 EVO BLACK TECH 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.
- 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.
- New spring insulating coating, body insulating bushing (non-metal cylindrical interface separating metal parts from water), anti-freeze cap, bigger body and cap thread all work in concert with the XTIS to improve cold-water performance (key insulation system components are visible in blue).
- 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.
G260 BLACK TECH Second Stage:
- Air-balanced valve smoothes out the inhalation effort at varying depths and supply pressures.
- Nylon fiberglass design features SCUBAPRO’s biggest second stage casing and diaphragm for the ultimate in breathing sensitivity, regardless of position in the water.
- Dark anodized aluminum front cover ring adds scratch resistance without adding weight.
- Metal components, including metal air barrel and metal valve inlet tube, increase resistance to freezing when diving in extreme conditions.
- High-flow exhaust valve reduces exhalation for better overall breathing comfort.
- A diver-adjustable inhalation effort knob fine-tunes air delivery to suit changing depths, water conditions and personal tastes.
- Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch pre- vents free flows in cold water or when used as an octopus.
- Reversible hose attachment allows you to easily adjust hose routing for tech diving configurations.
- Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
- Ultra-comfortable orthodontic mouthpiece is easy to grip yet doesn’t inhibit airflow.
- Weight: 9.7oz/275g.
- Airflow at 2900psi/200bar: 1800 l/min – 64 SCFM.
- Maximum low pressure: 203psi/14bar.
