The R-400 DIN First stage features a balanced diaphragm system and upgraded HP poppet assembly for enhanced reliability in 2008-09. 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 diaphragm first stage also offers excellent performance in all water conditions due to its sealed design. Two high flow ports are engineered for the smoothest air delivery possible to the primary second stage and octopus at all tank pressures. The R-400 first stage features a special coating on the main spring to ensure that the regulator performs in all diving conditions including cold water

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.
