AquaLung Legend 3 MBS Regulator Set Yoke

The Aqualung Legend 3 MBS Regulator Set Yoke is the latest and greatest underwater breathing technology. It is Aqualung’s best-selling and highest-performing regulator, capable of outperforming anything else in any condition – whether you’re diving under ice at one of the poles or on a tropical reef. The Legend 3 has a unique combined adjustment that controls the inhalation effort and venturi effect automatically.

The Master Breathing System is a new way to adjust the comfort on a second stage. The diver can perfectly master breathing comfort in one simple rotation. With the MBS on minimum position (only one full rotation), the spring is fully compressed and inhalation effort is about 3 mbar higher. Free flow is contained when the venturi blade restricts the injection outlet. With the MBS on maximum.

Aqualung has solved two longstanding problems for technical divers: free flows when switching tanks and extremely high work of breathing when diving in cold water with drysuits.

Legend 3 MBS Regulator Set Includes

• Aqualung Legend 3 MBS Regulator din or yoke
• Aqualung Legend 3 Octopus

Legend 3 MBS Regulator

First Stage

• When the first stage is not attached to a cylinder valve, the Auto Closure Device (ACD) keeps the inlet shut to protect the first stage, and 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 Aqualung’s three anti-freeze properties:

1. 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 from forming on the mechanism (+30% vs Glacia / +70% vs Legend 2)
   3. The new over-moulded 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
• Channelled 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-moulded 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
• A 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 the freezing of the second stage mechanism
• Air channel deflector
• Directs the airflow evenly during the inhalation phase
• A streamlined bi-material deflector lowers the exhalation effort
• Flexible and lightweight Aqua Flex hose with dual protectors

LEG3ND Octopus

When performance is your highest priority, LEG3ND is the answer as LEG3ND shares the same breathing characteristics with the LEG3ND ELITE and LEG3ND MBS. The simple Venturi switch now features an updated and ergonomic design. Because your sensations and emotions are amplified in the underwater world, you can focus on what matters: feeling free.
