Aqualung Legend MBS 2nd Stage

Aqualung LEG3ND MBS regulator 

• Aqualung's Master Breathing System (MBS)  controls venturi and inhalation
• ACD keeps contaminants out of first stage.

The LEG3ND MBS regulator  is a unique combined adjustment, it controls the inhalation effort and the 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 the inhalation effort is about 3 mbar higher. A free flow is contained when the venturi blade restricts the injection outlet. With the MBS on maximum position the injection of the airstream is unrestricted and the flow is maximized.

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
