Product Information
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.
- R-700 first stage with Dry Ambient Pressure Chamber keeps water off the diaphragm and spring for reliable performance in cold water below 50°F/10°C.
- Six-port first stage: two high-flow LP ports plus two standard LP and two HP ports positioned near the diaphragm for up to 15% more air flow.
- S-90 second stage is pneumatically balanced to reduce inhalation resistance for smoother breathing.
- Two-position Venturi lever on the RS-790 switches between Surface/minimum and Dive/maximum airflow settings.
- SS-0001 octopus has a lightweight, compact composite case configurable for left- or right-hand hose routing.
- Ortho-consciously designed mouthpiece on the SS-0001 is built to reduce jaw fatigue on longer dives.
- 3-gauge console combines a 500 psi pressure gauge, a depth gauge in feet, and a Northern Hemisphere compass in one instrument.
- Matched Tusa set: primary regulator, backup octopus, and gauge console together, ready to dive as one complete system.

Frequently Asked Questions
What is the Tusa RS-790 dive regulator?
The RS-790 is a yoke-connection regulator built around Tusa's R-700 first stage and S-90 second stage. The R-700 uses a Dry Ambient Pressure Chamber to keep water off the diaphragm and spring, and the S-90 second stage is pneumatically balanced with a two-position Venturi lever for surface and dive airflow settings.
Is the Tusa RS-790 regulator good for cold water diving? (RS-790 review)
Yes, Tusa built the R-700 first stage with cold water in mind: the Dry Ambient Pressure Chamber keeps the diaphragm and spring dry, and a ribbed top cap acts like a radiator to transfer heat and help prevent the internal freezing that can occur as gas pressure drops in conditions below 50°F/10°C.
Does the Tusa RS-790 use a yoke or DIN fitting, and how many ports does it have?
The RS-790 uses a yoke connection. It has two high-pressure ports and four low-pressure ports (two high-flow, two standard), with the high-flow LP ports positioned near the diaphragm to increase air flow by up to 15%.
What's included in this Tusa RS-790 regulator bundle?
The bundle includes three Tusa pieces: the RS-790 yoke regulator (R-700 first stage paired with the S-90 second stage), the Safe Second SS-0001 octopus (configurable for left- or right-hand use), and the SC-0301 three-gauge console with a 500 psi pressure gauge, a feet-based depth gauge, and a Northern Hemisphere compass.
