The Aqualung LEG3ND ELITE gives divers unprecedented capabilities by providing perfect precision and enhanced ergonomics at your fingertips. Advanced divers appreciate the independent micro adjustments to fine-tune their own individual breathing preferences.

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.
• Exceptional cold-water performance is achieved by modernizing Aqua Lung's three anti-freeze properties:
  1. 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.
  2. 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).
  3. The new overmolded 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.
• 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.

Second Stage

• 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.
• 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.
