1A. CLOSED POSITION The best performing regulators just got even better! The Legend series of regulators are now equipped with our unique Auto-Closure Device (ACD).		1B. OPEN POSITION When the regulator is clamped onto the scuba cylinder, the inlet crown retracts thereby exposing the gas inlet in the center valve post. This provides a steady flow of breathing gas to the first stage without any restrictions.

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.
