Embark on a new aquatic adventure with the revolutionary Aqualung LEG3ND MBS Regulator. This cutting-edge regulator combines the power of the venturi effect and inhalation effort adjustment to deliver a natural and intuitive breathing experience. With Aqualung's Master Breathing System, divers can effortlessly control both these factors with a single rotation, ensuring unparalleled comfort at any depth and in any conditions. The Master Breathing System (MBS) is a game-changer in the world of diving. By providing a unique combined adjustment, it automatically controls the inhalation effort and venturi effect. With this innovative technology, you can perfectly master your breathing comfort with just one simple rotation. Say goodbye to complicated adjustments and hello to a hassle-free diving experience. But the Aqualung LEG3ND MBS Regulator offers more than just superior breathing performance. It is equipped with advanced features designed to enhance your diving experience. When the first stage is not connected to a cylinder valve, the Auto Closure Device (ACD) keeps the inlet shut, protecting the internal parts from contamination and corrosive water. The deep ribs on this regulator create a significantly larger heat exchange surface area, preventing ice formation by 30% compared to Glacia and 70% compared to the Legend 2. Ergonomically shaped DIN and YOKE screws, made with a bi-material Soft Grip surface, provide a better hold when installing or removing the first stage, even with cold hands. The new front cover opening channels allow water to flow sideways over the diaphragm, minimizing any disruptions in your diving experience. And with the overmolded exhaust cover made of elastomer with a soft touch effect, you can expect lasting durability and a comfortable feel. Experience the freedom of effortless breathing control with the Aqualung LEG3ND MBS Regulator. Dive into your next underwater adventure with confidence and let this exceptional regulator accompany you every step of the way.
