    Tusa RS-680 Scuba Regulator

    Tusa RS-680 Scuba Regulator Description:

    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.

    Tusa RS-680 Scuba Regulator Features:

    S.E.A. - Sequential Exhaust AssistThe 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.

    Exhalation resistance directly affects the diver’s natural breathing cycle. By reducing this resistance or increasing exhalation performance, the diver breathes more naturally and comfortably reducing respiration rate and air consumption. Paired with the R-600 first stage, the S-80 offers a seemingly effortless underwater experience regardless of the workload.

    Venturi AdjustmentThe addition of a venturi adjustment lever on the S-80 allows the regulator to power assist the diver when underwater utilizing the natural venturi effect. The diver can also adjust the lever to prevent free flow such as on a surface swim.

    Moisture Exchange PlateThe S-80 second stage incorporates a moisture exchange plate that captures condensation produced by inhalation and exhalation efforts. This condensation increases the humidity of the air breathed and helps to reduce that “dry mouth” sensation often experienced while diving.

    Breathing Resistance Adjustment ControlThe Breathing Resistance Adjustment Control on the S-80 allows the diver to simply adjust the flow of air according to their needs. The easy-adjust multiple click knob allows you to quickly and finely tune resistance.
