The TUSA regulator set RS-790 consists of the first stage R-700 and the second stage S-90; a very durable and comfortable reg combo. We have also added the SS0001 Octopus and an SPG/Twin Gauge to make the set ready to dive.

The R-700 first stage is the ideal partner for all adventures. It is a balanced diaphragm first stage featuring a dry ambient pressure chamber and an external rib section, almost doubling the surface area for thermal exchange. Both of those features are designed to make the regulator freeze-resistant in extremely cold waters.

The second stage, TUSA’s S-90, is a pneumatically balanced system. It comes in a compact composite housing that is designed to insulate and protect the regulator in extreme cold conditions for your ultimate dive experience. The venturi adjustment lever further gives you total control over the reg’s airflow.
