Pneumatically balanced, user-adjustable second stage
.This pneumatically balanced, adjustable second stage is sure to provide you the highest performance for many years. The pneumatically balanced second stage provides the lowest possible inhalation effort. The second stage adjustment allows you to adjust your breathing effort, fine-tuning the regulator to your desired setting throughout your dive.
The venturi assist deflector vane directs airflow from the valve directly to the mouthpiece producing a smooth "venturi assisted" inhalation. Turning the venturi assist down, to a pre-dive position, prevents regulator free-flow while on the surface.
