AQUALUNG Leg3nd MBS 2nd Stage Regulator

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.

Features:

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.
– Preserves the internal lubrication
– Keeps the inlet filter clean and dry
– Safer for elevated percentages of oxygen

Exceptional cold-water performance is achieved by modernizing Aqua Lung´s three anti-freeze properties:
– The LEG3ND´s integrated dry chamber keeps inner components clean and dry by isolating them from the outside environment
– 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)
– The new overmolded cap delays ice forming over the external diaphragm
– Auto-Balanced (also known as Over-Balanced)
– Progressive increase of the working pressure to maintain optimum breathing efforts: Depending on the diver´s depth, the working pressure of the first stage is automatically elevated to counteract the increased breathing air density
– 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
– Channeled YOKE screw to prevent water retention.
– Specialized ACD Dust cap attached to the regulator body to protect the inlet fitting and the ACD system from impacts or damage
– Perfectly positioned HP and MP ports provide optimal hose routing

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
