Aqualung Legand Elite Regulator

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's internal parts from contamination and corrosive water.
• Preserves the internal lubrication
• Keeps the inlet filter clean and dry
• Deep ribs create a large heat exchange surface area that helps to prevent ice from forming on the mechanism (+30% vs Glacia / +70% vs Legend 2)
• The new over-moulded cap delays ice forming over the external diaphragm
• 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
• Channelled YOKE screw to prevent water retention. 
• Safer for elevated percentages of oxygen
• 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
• 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 to provide optimal hose routing




Second Stage

• New front cover opening channels allow water to flow sideways over the diaphragm
• Radial openings to prevent free flows when diving in stronger currents
• Openings widened to reduce peak inspiratory flow by an impressive 20%
• New over-moulded exhaust cover made of elastomer with a “soft touch” effect
• Overmolded air purge
• A wide surface area makes regulator purging easier
• The purge depth controller optimizes airflow with minimal effort
• A patented Comfobite mouthpiece reduces jaw fatigue and secures the second stage more comfortably.
• A detachable and reusable mouthpiece clamp allows a quick and simple tool-free mouthpiece change without plastic waste.
• The enlarged heat exchanger helps to prevent the freezing of the second stage mechanism
• Air channel deflector
• Directs the air flow evenly during the inhalation phase
• A streamlined bi-material deflector lowers the exhalation effort
• Flexible and lightweight Aqua Flex hose with dual protectors
