The S600, with its rugged fiberglass casing and stainless steel front face and ring, delivers smooth and easy inhalation and exhalation while offering efficient user controls, including a powerful purge, an inhalation effort control knob and Venturi Initiated Vacuum Assist (VIVA) dive/pre-dive switch. It provides a steady, effortless flow of air, regardless of depth or workload. S600 Second Stage: Metal valve housing (barrel) is able to withstand years of aggressive diving. Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures. User controls include a diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch. 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): 7.1oz/200g. Airflow at 2900psi/200bar: 1850 l/min - 66 SCFM. Interchangeable purge covers allow you to make your regulator truly unique.
