- New front cover opening channels allow water to flow sideways over the diaphragm.
This is the new LEG3ND, a masterpiece of engineering. The LEG3ND regulator is for the passionate, the explorers, the ones for whom diving is more than a sport. Aqua Lung, the original pioneer of the scuba regulator, brings you the most capable, coveted and advanced line of regulators ever created. After all, the ocean is the ultimate proving ground – a place where respect is given and earned equally, where true Legends belong.
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.
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
Exceptional cold-water performance is achieved by modernizing Aqua Lung’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)
The new overmolded cap delays ice forming over the external diaphragm
First Stage Additional Features
Auto-Balanced (also known as Over-Balanced)
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
Ergonomically shaped DIN and YOKE screws made of a bi-material “Soft Grip” surface provide a better hold when installing or removing the first stage – especially with cold hands
Channeled YOKE screw to prevent water retention.
Specialized ACD Dust cap attached to the regulator body to protect the inlet fitting and the ACD system from impacts or damage
Perfectly positioned HP and MP ports provide optimal hose routing
New front cover opening channels allow water to flow sideways over the diaphragm
Radial openings to prevent freeflows when diving in stronger currents
Openings widened to reduce peak inspiratory flow by an impressive 20%
New overmolded exhaust cover made of elastomer with a “soft touch” effect. Overmolded air purge
Wide surface area makes regulator purging easier
Purge depth controller optimizes air flow with minimal effort
Second Stage Additional Features
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
Air channel deflector
Directs the air flow evenly during the inhalation phase
Streamlined bi-material deflector lowers the exhalation effort
Flexible and lightweight Aqua Flex hose with dual protectors
