AQUALUNG REG, LEG3ND MBS, DIN

The first inhalation under water is the start of a new adventure. The revolutionary combination of Venturi effect and inhalation effort adjustment is natural and intuitive. Aqua Lung's Master Breathing System allows divers to control both in one simple rotation. All depths, all conditions, all dives - MBS will adapt.

First Stage:

• 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 over-molded 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 to provide optimal hose routing

Second Stage:

• New front cover opening channels allow water to flow sideways over the diaphragm
  • Radial openings to prevent free flows when diving in stronger currents
  • Openings widened to reduce peak inspiratory flow by an impressive 20%
• New over-molded exhaust cover made of elastomer with a “soft touch” effect
• Overmolded air purge
  • The wide surface area makes regulator purging easier
  • The purge depth controller optimizes airflow with minimal effort
• Patented Comfobite mouthpiece reduces jaw fatigue and secures the second stage more comfortably.
• A 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 airflow evenly during the inhalation phase
  • Streamlined bi-material deflector lowers the exhalation effort
• Flexible and lightweight Aqua Flex hose with dual protectors
