First Stage
- Air balanced flow-through piston in a Black Tech-coated brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
- Patented 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 compromising breathing 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 and one axial super 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 232bar INT or 300 bar DIN configuration.
- Weight: INT 232 : 790g; DIN 300 : 572g
- Airflow at 200bar: (l/min): >8500.
- Intermediate pressure (bar): 9.0-9.8.
Second Stage
- Air-balanced valve smoothes 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.
- 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 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.
- Weight: 275g.
- Airflow at 200bar: 1800 l/min .
