MK17 EVO/G260

MK17 EVO/G260

The MK17 EVO is completely sealed off from the elements, ensuring trouble-free operation no matter how cold or murky the water gets. It is more compact yet delivers better breathing performance than its predecessor. Its improved internal design allows more airflow from the LP ports which have been reconfigured for better hose routing. Teamed with the venerable G260, this system can be relied upon to deliver top-of-the-line performance in the most extreme conditions.

Features first stage

• Air-balanced diaphragm delivers constant and effortless airflow unaffected by
  depth, tank pressure, or breathing rate.
• Environmentally sealed system prevents water and pollutants from fouling the
  inner mechanism.
• Dry ambient pressure chamber increases freezing resistance, ensuring consistent
  airflow in the coldest conditions.
• Substantial increase in airflow — 6900 l/min versus 6500 l/min — includes
  improved balance of air supply pressure.
• Two high pressure and four high-flow low pressure ports maximize air delivery.
• High-flow performance is available from all four LP ports which are configured for
  optimum hose routing.
• External intermediate pressure adjustment enables technicians to fine-tune
  performance quickly and easily.
• Weigh : INT 232: 860g; DIN 300: 640g
• Airflow at 200bar: (l/min): 242.
• Intermediate pressure: 9.0-9.8 bar

Features 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.
• 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 prevents 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.
• Airflow at 200bar: 1800 l/min.
