01. Info
The S3 is HOTDIVE’s balanced diaphragm first stage for divers who ask more of their scuba diving regulator. The diaphragm design keeps the valve mechanism isolated from water, silt and contaminants — the layout of choice for demanding conditions — and the balanced mechanism guarantees consistent performance at any depth and with any supply pressure. A swivel turret puts five LP ports exactly where clean hose routing wants them, whether you are rigging a single-tank recreational setup, sidemount or doubles.
