This set pairs the Tusa RS-790 Dive Regulator Yoke with a Tusa Safe Second SS-0001 octopus and a Tusa 3-gauge console, so you leave with a complete, matched setup instead of sourcing each piece separately. The RS-790’s R-700 first stage uses a Dry Ambient Pressure Chamber to keep water off the diaphragm and spring, paired with a ribbed top cap that transfers heat to the internal parts most likely to freeze up in cold water below 50°F/10°C. Six ports, two high-flow low-pressure ports plus two standard LP and two HP, sit near the diaphragm for up to 15% more air flow, and the S-90 second stage is pneumatically balanced with a two-position Venturi lever for surface and dive settings.
The SS-0001 octopus backs up that first stage with a lightweight composite case that switches between left- and right-hand hose configurations, so you can route it wherever it sits best on your rig. It carries its own Venturi adjustment lever and an ortho-consciously designed mouthpiece meant to cut down on jaw fatigue over longer dives.
Rounding out the set, the Tusa 3-gauge console puts a 500 psi pressure gauge, a depth gauge in feet, and a Northern Hemisphere-balanced compass on one analog instrument, so you can track air, depth, and direction without adding separate gear to your kit. Together, the RS-790, SS-0001 octopus, and 3-gauge console give you a first stage, backup second stage, and instrumentation from the same Tusa lineup in a single purchase.
