01. Info
The ST3 pairs the S3 balanced diaphragm first stage with the T3 balanced adjustable second stage for divers who ask more of their equipment. The diaphragm design keeps the valve mechanism isolated from water, silt and contaminants — the layout of choice for demanding conditions — while the swivel turret puts five LP ports exactly where technical hose routing wants them. Balanced at both stages, the ST3 delivers smooth, consistent air from the first breath of the dive to the last stop of the deco.
