Unique over-balanced, diaphragm design - as the diver descends, the over-balancing feature allows the medium pressure gas in the hose to increase at a rate faster than ambient. This results in superior performance at depth.
An environmental dry system keeps water out of the main spring chamber thus preventing ice buildup and keeping silt and contamination out.
Pneumatically-balanced second stage results in smooth, easy breathing.
Easy-to-grip opening effort control knob keeps the diver in control.
A silicone exhaust valve improves the breathing performance of the regulator.
A heat exchanger (patented) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water.
The Comfo-bite mouthpiece virtually eliminates jaw-fatigue.
