Aqualung Legend 3 Elite Regulator

The Leg3nd Elite gives you separate control of Venturi assistance and inhalation effort. Paired with an over-balanced first stage, a permanent dry chamber and automatic inlet closure, it suits divers who want detailed adjustment alongside protection for regular warm- and cold-water diving.

Features and benefits

Balanced gas delivery. The over-balanced diaphragm mechanism helps manage the supply to the second stage as diving conditions change.
Balanced second stage. The balanced valve helps maintain a consistent inhalation response.
Adjustable breathing feel. The inhalation-effort control lets you tune the adjustable second stage within its operating range.
Venturi control. Select the appropriate setting for surface handling or diving to help manage free-flow tendency.
Environmental protection. The sealed first-stage chamber helps keep water and contaminants away from its working mechanism.
Automatic inlet closure. The inlet closes when disconnected from the cylinder to help protect the first stage from water and debris.
Comfortable mouthpiece hold. The Comfo-Bite palate bridge helps support the second stage without a hard bite.

Setup and compatibility

Connection: DIN, Yoke. Choose the fitting that matches your cylinder valve and its pressure rating.

The Legend 3 Regulators are a luxurious addition to any diving gear, with a PVD finish that looks like traditional chrome plating. Smart, innovative, and feature-rich, the Legend LX is engineered for longevity and unsurpassed breathing performance.

Legend 3 Elite First Stage

Over-balanced Diaphragm Unique, over-balanced diaphragm results in superior performance at depth
HP/MP Ports and "T" Shape 2 HP ports (7/16") and 4 MP ports (3/8"), Precisely oriented streamlined hose positioning
Yoke or DIN Available in yoke (3,300psi/232 bar max.) or DIN (4,350psi/300 bar max.)

Pneumatically Balanced Pneumatically balanced for smooth, easy breathing
Braided Hose Attached to a 29" braided Aqua Flex hose that is lightweight and extremely pliable, eliminating strain from tugging on the mouthpiece
