Description
- When the first stage is not connected to a cylinder valve, the Auto Closure Device (ACD) keeps the inlet shut to protect the first stage internal parts from contamination and corrosive water.
- Deep ribs create a large heat exchange surface area that helps to prevent ice forming on the mechanism (+30% vs Glacia / +70% vs Legend 2)
- 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
- New front cover opening channels allow water to flow sideways over the diaphragm
- New overmolded exhaust cover made of elastomer with a “soft touch” effect
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.
