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.

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.

The MBS is a unique combined adjustment, it controls the inhalation effort and

the venturi effect automatically.

With the MBS on minimum position (only one full rotation): The spring is fully

compressed and the inhalation effort is about 1.2 In/H2O (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.
