When performance is your highest priority, LEG3ND is the answer.

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.
