First degree:
Unique Overbalanced Diaphragm Design - As the diver descends, the overbalancing feature allows the medium pressure gas in the hose to increase at a rate faster than the ambient. This results in superior performance at depth.
2 HP ports and 4 MP ports angled for optimal hose routing.
An eco-friendly dry system keeps water out of the main spring chamber, preventing ice buildup and protecting against sludge and contamination.

Second degree:
The pneumatically balanced second stage results in smooth and easy breathing.

The Venturi lever has a soft rubber grip that makes it easier to find and use.
The Comfo-bite™ eliminates jaw fatigue.
