Tusa RS680 Regulator
The RS-680 is TUSA’s latest regulator that delivers superior performance and build quality in a compact lightweight design. The R-600 paired with the newly developed S-80 second stage further pushes the regulator 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.
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 Adjustment The 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 Plate The 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 Control The 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.

Tusa RS860 Regulator
The balanced piston R-800 first stage is compact and lightweight. It has a full complement of four low-pressure and two high-pressure ports and is fine- tuned for optimum performance.
The S-60 second stage features a diver adjustable sensitivity control to deliver air smoothly with each breath. The surface position decreases the likelihood of a free flow and also is recommended for cold water diving. In the dive position the control allows the regulator to power assist the diver as they breathe using the venturi effect. The S-60 is also equipped with an ortho-consciously designed mouthpiece to increase comfort and reduce jaw fatigue.
The RS-860 is available in both INT (yoke) and DIN versions.

Tusa RS460 Mk II Regulator
The R-400 First stage features a balanced diaphragm system and upgraded HP poppet assembly for enhanced reliability. This balanced diaphragm system maintains minimum variation in intermediate pressure in relation to changes in residual tank pressure. The first stage features two high flow low-pressure ports to optimize second stage performance for easier breathing.
The S-60 second stage features a diver adjustable sensitivity control to deliver air smoothly with each breath. The exhaust valve features a large and flexible design for extremely low exhaust resistance.
Scubapro Mk25/S600 Titanium Regulator
