Auto-Closure Device (ACD) seals the regulator’s inlet fitting, both Yoke and DIN, as soon as the regulator
 is removed from the cylinder valve.

• • This will keep water and contaminants out of the regulator’s first stage during rinsing and storage.

• • It allows the first stage to maintain peak performance over time

• • The first stage will retain its internal lubrication longer

• • Makes the first stage safer for nitrox use

The new ACD feature coupled with the environmental dry chamber, results in a first stage that is
completely sealed off from the environment.

Over-balanced diaphragm design delivers superior breathing performance even at increased depths

Environmentally sealed dry chamber helps resist freezing and keeps the internal mechanism clean and dry

Inhalation adjustment feature permits diver to control breathing gas delivery under a variety of diving conditions

Pneumatically balanced second stage provides consistent ease of inhalation at any tank pressure

Aqua Lung's "Air Turbo System" integrated into the forward medium pressure ports, boosts the regulator's
 breathing performance

Diver-controlled Venturi Adjustment Switch (VAS) reduces sensitivity to free flow on the surface and provides
 maximum airflow at depth

Exclusive Comfo-Bite™ mouthpiece virtually eliminates jaw fatigue

Two high-pressure ports and four low-pressure ports, angled for optimal hose configuration

Black polyurethane coating protects the exterior metal surfaces
