Features:

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
