The RS-681 regulator from TUSA combines a compact, lightweight design with strong performance for scuba and diving adventures. The ultra-compact balanced diaphragm R-600 first stage is paired with the new S-81 second stage to deliver smooth breathing in a small, reliable package.
Designed with practical features for field use, the R-600 first stage offers 2 HP ports and 4 LP ports, a Venturi adjustment lever, and a built-in moisture exchange plate. The elliptical low-profile case design, along with a MIFLEX hose, enhances flexibility and reduces snag risk during underwater exploration.
Compatibility and comfort are supported by options such as the EK-600 cold water kit for temperatures below 50°F/10°C and the DIN-R600 conversion kit (300 bar/4350 psi). An ortho-consciously designed mouthpiece and Breathing Resistance Adjustment Control provide a tailored feel for divers, while S.E.A. (Sequential Exhaust Assist) helps manage exhaust flow.
