AquaLung Legend ACD Supreme Regulator

For the diver that wants performance but would rather not use breathing control adjustment knobs. The Legend ACD Supreme uses the same first stage as the LX. The second stage is pneumatically balanced, which provides consistent inhalationeffort at all depths and conditions. The venturi lever is large and easy to use;the compact, lightweight second stage virtually eliminates jaw fatigue. The Legend ACD Supreme comes with a Comfo-Bite mouthpiece, a standard spare mouthpiece and a reusable mouthpiece clamp. Regulator is specific to cold water diving, allowing it to surpass the stringent CE standard for cold water requirements. Recommended for when the water temperature drops below 50F or 10C.A second stage lip shield keeps lips warm. <br><br> Auto-Closure Device (ACD): This new safety feature provided on inner fitting of Yoke and the DIN, keeps the 1st stage closed and protected from the environment immediately after being removed from cylinder valve, to prevent water and contaminants from entering inside the 1st stage, preserving the peak performance of your regulator and maintaining the internal lubrication for a longer period, adding peace of mind during rinsing transfer and storage, also making it safer for nitrox use.
