1st Stage: Air-balanced diaphragm design: consistent and smooth airflow regardless of depth, tank pressure, or breathing rate.
Internal body components made of marine-grade brass – sealed to prevent water and pollutants from entering, as well as improving cold-water performance.
Two high-pressure ports, two low-pressure ports, and two high-flow (LP) ports.
External intermediate pressure adjustment.
DIN 300.
Weight: 490 grams.

2nd Stage: Pneumatically balanced valve: relieves inhalation effort at different depths and with different supply pressures.
Fiberglass-reinforced nylon casing (compact and robust) and the new “T” exhaust connection allow for minimal space in the bag.
Full shell featuring a stainless steel frame.
New exhaust valve, inspired by the S620Ti, helps improve inhalation effort by 10%.
User controls include an inhalation effort adjustment knob and a Venturi-Initiated Vacuum Assist (VIVA).
Large purge button is easy to activate, even with thick gloves.
Oversized super-flow hose allows for increased airflow with each inhalation.
Hi-Flow mouthpiece improves both airflow and comfort, adapting to all mouth sizes.
