Aqua Lung Leg3nd MBS Regulator Set

The first stage when not connected to a cylinder valve, the Auto Closure Device (ACD) keeps the inlet closed to protect the internal parts of the first stage from contamination and corrosive water. preserves internal lubrication keeps the inlet filter clean and dry safer for higher oxygen percentages exceptional cold-water performance is achieved by updating Aqua Lung's three anti-freeze properties: where there is no moisture, there is no ice: the Legend's integrated dry chamber keeps internal components clean and dry by isolating them from the external environment deep ribs create a large heat exchange surface area that helps prevent ice formation on the mechanism (+30% vs Glacia / +70% vs Legend 2) the new overmoulded cap delays ice formation over the external diaphragm auto-balanced (also known as over-balanced) gradual increase of working pressure to maintain optimal breathing efforts: depending on the diver's depth, the working pressure of the first stage is automatically increased to counteract the increased breathing air density ergonomically shaped DIN and YOKE screws made of a bi-material Soft Grip surface provide a better grip when installing or removing the first stage especially with cold hands channelled 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 free flows when diving in stronger currents openings widened to reduce peak inhalation flow by 20% new overmoulded exhaust cover made of elastomer with a soft touch effect overmoulded air purge wide surface area makes regulator purging easier purge depth controller optimizes airflow with minimal effort patented Comfobite mouthpiece reduces jaw fatigue and secures the second stage more comfortably detachable and reusable mouthpiece clamp allows quick and simple tool-free mouthpiece change without plastic waste the enlarged heat exchanger helps prevent freezing of the second stage mechanism air channel deflector directs airflow evenly during inhalation phase streamlined bi-material deflector reduces exhalation effort flexible and lightweight Aqua Flex hose with dual protectors
