Nylon fiberglass design features SCUBAPRO’s largest 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.
Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
High-flow exhaust valve reduces exhalation for better overall breathing comfort.
Diver-adjustable inhalation effort knob fine-tunes air delivery to suit 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 (without mouthpiece): 9.5oz/268g.
Airflow at 2900psi/200bar: 1800 l/min – 64 SCFM.
