The Tusa RS-790 Regulator Set delivers outstanding performance, durability, and comfort, making it the ideal choice for discerning divers. This package includes the R-700 first stage, the S-90 second stage, the SS0001 safe-second, and the RCB-1 regulator carry bag. Designed to perform exceptionally well in cold-water conditions, this combo ensures a safe and comfortable diving experience even in the most extreme environments.

The R-700 first stage is a balanced diaphragm system designed specifically for cold-water use. It features a dry ambient pressure chamber and an external rib section to enhance thermal exchange, significantly reducing the risk of ice formation and freeze-up in temperatures below 50°F/10°C. With two high pressure (H.P.) ports and four low pressure (L.P.) ports, including two high flow ports that offer up to a 15% increase in air flow, the R-700 ensures maximum performance and reliability.

The S-90 second stage is a compact, pneumatically balanced system designed with a composite housing that provides excellent insulation and protection in extreme cold-water conditions. It includes a built-in venturi adjustment lever that allows divers to select between a surface setting to reduce free flow and a dive setting for maximum air flow during the dive.

The SS0001 Octopus is a versatile backup regulator with a lightweight and compact composite case design. It allows for both left and right hand configuration, making it adaptable for any diver. The safe-second also features a venturi adjustment lever for easier breathing and an ortho-conscious mouthpiece for enhanced comfort.

The Tusa Gauge is a heavy-duty pressure gauge ideal for divers using a wrist-type dive computer like the IQ-650, IQ-750 and IQ-900. The console provides continuous air pressure and temperature in a low-profile rubberized boot. The pressure gauge features a luminescent light storage dial that is highly legible in dark or low visibility conditions. The entire face glows bright enough to make it ideal for night diving or diving in dark areas but contains no radioactive materials.

The RCB-1 regulator carry bag is designed to protect your regulator with its fully-lined thick padding. It features a durable zipper with pull tabs, an internal pocket for log and manuals, and an included shoulder strap for easy carrying.
