The SS0001 safe-second has a lightweight and compact composite case design and allows for both left-and-right-hand configuration. The SS0001 features a venturi adjustment lever for easier breathing and an ortho-conscious mouthpiece. The SS0001 combines a classic downstream valve with a large diaphragm and classic purge button. It’s simple and robust construction with a techno-polymer valve housing offers the utmost in reliability and makes the SS0001 the ideal second stage for new divers and a perfect choice for deco tanks thanks to its reversible hose attachment. Classic downstream valves are particularly noted for their legendary safety and reliability. When in use, the downstream valve opens in the same direction as the incoming airflow. To close the valve and stop the airflow, a spring counteracts the force of the incoming air. Therefore, a certain inhalation effort is always required to overcome the spring tension and open the valve.
