Aqua Lung


If you want high-performance features and ease of breathing, you'll find it with the LEG3ND MBS. The Master Breathing System (MBS) controls venturi and inhalation and enables divers to perfect breathing comfort in one simple rotation.

This is a special order product and may take two weeks to be shipped

  • First Stage:

    • 2 HP ports and 4 MP ports are angled for optimum hose configuration
    • Auto Closure Device (ACD) - keeps corrosive water out of the first stage inlet by automatically closing as the LEG3ND MBS is removed from the cylinder valve
      • This prevents internal lubrication from washing away
      • Safer for elevated percentages of oxygen
    • Unique over-balanced, diaphragm design results in superior performance at depth
    • An environmental dry system keeps water out of the main spring chamber thus preventing ice buildup and keeping silt and contamination out
    • Available in your choice of yoke or DIN connectors

    Second Stage:

    • Master Breathing System (MBS) - The MBS is a simple and effective way to adjust the breathing performance of your LEG3ND MBS. The MBS controls two functions at one time. It controls the direction of air, which alters the venturi effect, as well as changes the opening effort. One control – two functions, it doesn’t get easier
    • Auto(over)-balanced second stage results in smooth, easy breathing
    • The Comfobite™ mouthpiece virtually eliminates jaw-fatigue
    • Exceptional coldwater performance: Deep ribs create a large heat exchange surface area that helps to prevent ice forming on the mechanism (+30% vs Glacia / +70% vs LEG3ND MBS)
    • The ergonomic exhaust tee channels the exhaust bubbles out of your field of vision. The design also contributes to a reduction in exhalation effort
    • Attached to a 29” braided Aqua Flex hose. These hoses are lightweight and extremely pliable which eliminates any tugging on the mouthpiece
  • First Stage Diaphragm, over-balanced, environmentally sealed
    HP Ports 2
    LP Ports 4
    Second Stage Auto-Balanced (also known Over-Balanced)
    Controls Master Breathing System knob
    Breathing Resistance User adjustable
