In the Box: Aqua Lung LEG3ND Yoke first stage, second stage, and user’s guide. First Stage First Stage When the first stage is not connected to a cylinder valve, the Auto Closure Device (ACD) keeps the inlet shut to protect the first stage internal parts from contamination and corrosive water. Preserves the internal lubrication
Keeps the inlet filter clean and dry
Safer for elevated percentages of oxygen

First Stage When the first stage is not connected to a cylinder valve, the Auto Closure Device (ACD) keeps the inlet shut to protect the first stage internal parts from contamination and corrosive water.
Exceptional cold-water performance. The LEG3ND’s integrated dry chamber keeps inner components clean and dry by isolating them from the outside environment. Deep ribs create a large heat exchange surface area that helps to prevent ice forming on the mechanism.
The new overmolded cap delays ice forming over the external diaphragm

1st Stage: The balanced diaphragm mechanism allows for ease of breathing and consistent performance while protecting internal moving parts from the environment
The T-shape design is compact and provides optimal hose routing
The unique forged body uses less brass, making it more compact and lighter weight than other regulators
