What's in the box: 1st and 2nd stages, LP hose.
The first stage features a balanced diaphragm system. This balanced diaphragm system maintains minimum variation in intermediate pressure In relation to changes in residual tank pressure. The ports feature two high flow low-pressure ports to optimize second stage performance for easier breathing.
The S-60 second stage features a diver adjustable sensitivity control to deliver air smoothly with each breath. The exhaust valve features a large and flexible design for extremely low exhaust resistance. The "Surface" or "Dive" control allows the user to set the ease of breathing for varying sections of the dive. The surface position decreases the likelihood of a free flow and also is recommended for cold water diving. In the dive position the control allows the regulator to power assist the diver as they breathe using the venture effect.
