This regulator's MR12S first stage provides stellar performance at a low price point while the MV second stage delivers air flow at any angle. The slim design and low profile makes this regulator ideal for travel. Four pre-oriented low-pressure ports and two high-pressure ports allow you to create a wide range of configuration options. The diaphragm system isolates the mechanics from the water, and the balancing technology ensures immediate delivery of air regardless of the pressure in the tank.Dynamic Flow Control (DFC) System: Minimizes the pressure drop that occurs in all regulator first stages when the diver inhales. The deeper the dive, the demand from airflow from the regulator rises. The DFC system operates in relation to the diver's actual air demand, independent of depth and tank pressure. It uses the Venturi Effect, optimizing the regulator's sensitivity and minimizing inhalation resistance, especially during dives in extreme conditions.Features:Material: Brass, Plastic, ChromeHigh performance tri-material valveINT/DIN/Nitrox CompatibleTwo year limited warranty
