TUSA RS-790 Regulator

The TUSA RS-790 Regulator represents the pinnacle of Japanese diving technology. Designed to take on the challenges of even the most hostile diving environments the RS-790 is able to take on waters in temperatures below 10*C with unparalleled performance.

The R-700 first stage features a balanced diaphragm first stage with anti-freeze system for exceptionally easy breathing throughout your dive. A Dry ambient pressure chamber prevents water contacting with the diaphragm improving performance and preventing ice build, even in sub 10*C water. The top cap is ribbed like a radiator increasing its surface area for improved heat transfer allowing the internals of the first stage to retain heat, preventing freezing.

Two high flow ports and two Low pressure ports allow you to install all the gear you need for your dive with 15% increase in air flow.

The pneumatically balanced second stage ensures your breathing is consistent and clean even when the tank begins to empty of air or at extreme depths when breathing often becomes difficult. A robust composite housing not only protects your second stage from damage but insulates it against the cold, preventing ice build-up and warming the air you’re breathing for a more comfortable experience. The Venturi switch on the 2nd stage allows you to control and free flow of air to the mouthpiece ensuring you don’t waste oxygen when you’re at the surface or not wearing the mouthpiece.
