AquaLung Leg3nd DIN

When performance is your highest priority, LEG3ND is the answer. The LEG3ND shares the same breathing characteristics with the LEG3ND ELITE and LEG3ND MBS. The familiar venturi switch now features an updated and ergonomic design. Overmolded with “soft touch” elastomer, the ergonomically designed switch perfectly controls the venturi effect, either allowing or containing a natural freeflow.​


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 is achieved by modernizing Aqualung's three anti-freeze properties: where there's no moisture, there's no ice. 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 (+30% vs Glacia / +70% vs Legend 2).

Progressive increase of the working pressure to maintain optimum breathing efforts: Depending on the diver's depth, the working pressure of the first stage is automatically elevated to counteract the increased breathing air density.

Specialized ACD Dust cap attached to the regulator body to protect the inlet fitting and the ACD system from impacts or damage.

Second Stage

New front cover opening channels allow water to flow sideways over the diaphragm. Radial openings prevent freeflows when diving in stronger currents.

Patented Comfobite mouthpiece reduces jaw fatigue and secures the second stage more comfortably. Detachable and reusable mouthpiece clamp allows a quick and simple tool-free mouthpiece change without plastic waste.

The enlarged heat exchanger helps to prevent freezing of the second stage mechanism.
