Whats in the box:1st Stage, 2nd Stage and LP Hose
First Stage The balance diaphragm first stage of the ATX range is pressure adjustable and depth compensated. The dry seal first stage is ideal for cold, warm, and contaminated waters and doesn't require modifications to switch between various water environments.
Second Stage The ATX50 second stage uses a pneumatically-balanced valve system and is the most advanced diver adjustable breathing system available. The ATX50 has ergonomically-designed diver-adjustable controls for opening effort and venturi assistance allowing the diver to tune the breathing characteristics of the regulator to give virtually ideal breathing. No fixed or present system can achieve an ideal level of breathing performance under all conditions.
The ATX50 second stage is suitable for all diving conditions. Because of its high-efficiency heat exchanger system, it can cope with even the coldest conditions without freezing, making the perfect all-around regulator. It also comes standard with the Comfo-bit mouthpiece for increased comfort.
