LEG3ND







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.​

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

Aqua Lung Regulators

Aqua Lung is synonymous with the modern scuba regulator. Over 70 years of innovation have gone into making scuba regulators that are safer and easier to use than others on the market. An Aqua Lung scuba regulator offers you comfort, ease of breathing, control and peak performance.

Aqua Lung and the scuba regulator share a rich history, and now is your chance to play a part. Choose the right scuba regulator to ensure your next dive is comfortable and safe.

Aqua Lung: Industry-Leading Scuba Regulators

Aqua Lung has developed diving regulators built for new and experienced divers, as well as for a range of diving conditions.

Our premier and iconic line of Legend regulators feature an overbalanced diaphragm designed to provide excellent breathing performance. The Legend range features premium engineering, with such features as our unique Auto-Closure Device (ACD). With the ACD, divers don’t have to worry that water or silt will enter the first stage.

We have a line of Legend models to fit your needs perfectly. These models range from the Legend LX/LX Supreme with the Master Breathing System (MBS) to the Glacia that offers even greater freezing resistance for cold water diving.

Beside the Legend, Aqua Lung has a broad range of scuba regulators to fit your needs, including:

  • CORE - Better breathing at an affordable price
  • CORE Supreme - Affordable, efficient, and 2015 Tester’s Choice
  • Mikron - Lightweight, designed for travel and balanced
  • Titan - Rugged and comfy, with two versions to choose from
  • Calypso - Simple, robust design with solid performance ideal for new divers

Aqua Lung dive equipment is designed to be simple, sleek, and efficient, and each dive regulator series upholds the highest standards of quality for your diving safety.

Innovation Since 1943

Since 1943, Aqua Lung has been the expert in scuba regulators. Now you can carry on the spirit of that first dive with an Aqua Lung dive regulator that will perfectly suit your diving needs.
