The 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
Additional First Stage 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

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

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
  • Flexible and lightweight Aqua Flex hose with dual protectors

Air channel deflector

  • Directs the air flow evenly during the inhalation phase
  • Streamlined bi-material deflector lowers the exhalation effort
