The R-600 first stage is incredibly light weight weighing in at 630g. Made to exacting EN-250 standards, the R600 adds performance plus to the TUSA range. The ultra-compact unit is a balanced diaphragm design, featuring four, low pressure and two high pressure ports allowing the diver a choice of setup configurations.

Available in both DIN and yoke, the regulator is manufactured in Japan ensuring the diver of high quality machining and construction.

The new S70 second stage is also manufactured in Japan and features an Air Injection Tube, to deliver air directly to the mouthpiece. The Injection Tube smooths out the air flow and reduces breathing effort with venturi assistance. The regulator has a Sensitivity Control Knob allowing the diver to custom tune their breathing resistance for various diving depths and situations. It also has the added benefit of reducing spring pressure on the LP seat for storage allowing the regulator to maintain tune over a longer period of time.
The mouthpiece is ortho-ergonomically designed to enhance the comfort of bite and fit. Even with a light bite, a high level of stability and security is achieved so there is reduced fatigue during long periods of usage.
A universal swivel hose joint is fitted to the LP hose reducing pull on the diver?s jaw. This swivel is designed for TUSA regulators so it does not reduce air flow, it further enhances comfort and performance.

All RS-670 regulators are tested on TUSA?s ANSTI machine prior to despatch, this final check guarantees every regulator meets the factory designed performance specification.
