First Stage:

  • Auto Closure Device (ACD) - keeps corrosive water out of the first stage inlet by automatically closing as the Legend 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

  • 2 HP ports and 4 MP ports are angled for optimum hose routing

  • An environmental dry system keeps water out of the main spring chamber thus preventing ice buildup and keeping silt and contamination out

  • Available in yoke connector

  • Compatible with up to 40% O2 right out of the box

Second Stage:

  • Master Breathing System (MBS) - The MBS is a new, simple and effective way to adjust the breathing performance of your Legend LUX. 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.

  • Pneumatically-balanced second stage results in smooth, easy breathing

  • The Comfo-Bite™ mouthpiece virtually eliminates jaw-fatigue

  • Heat exchanger (patented) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water

  • 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
