MK17 EVO 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.
- More compact design features a smaller dry ambient pressure chamber and spring, although the bulletproof inner parts remain the same.
- 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 ports maximize air delivery and hose routing options.
- High-flow performance is available from all four LP ports which are configured for optimum hose routing.
- Available in a 3364psi/232bar INT configuration.
- Weight: INT 232 – 30oz/850g.
- Airflow at 2900psi/200bar: 6900 l/ min – 230 SCFM.
- Intermediate pressure (psi/bar): 130-142/9.0-9.8.
G260 Second Stage:
- Nylon fiberglass design features SCUBAPRO’s largest second stage casing and diaphragm for the ultimate in breathing sensitivity, regardless of position in the water.
- Anodized aluminum front cover ring adds 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.
- Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
- 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 (larger inside hose diameter) 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: 1800 l/min – 64 SCFM.
- Maximum low pressure: 203psi/14bar.
