More views:

The RS-680 is TUSA's latest regulator that delivers superior performance and build quality in a compact lightweight design. Improving upon the R-670 released in 2009, the R-600 mated with a newly developed S-80 second stage further pushes the engineering and performance envelope.

The ultra-compact balanced diaphragm R-600 first stage is incredibly small and weighs only 630g. The R-600 is configured with 2 HP and 4 LP ports allowing for versatile hose placement. A DIN conversion kit (DIN-R600) and an environmental kit (EK-600) is also available.

The newly designed S-80 second stage offers the following features:

S.E.A. - Sequential Exhaust Assist
The Sequential Exhaust Assist (S.E.A.) is a revolutionary new second stage design featuring a dual exhaust system. The S.E.A. system consists of an enlarged primary and an auxiliary exhaust. The auxiliary exhaust, located on top of the S-80 elliptical case, works in union with the primary to significantly decrease exhalation resistance.
