The RS-681 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-81 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-81 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-81 elliptical case, works in conjunction 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-81 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.

Miflex® Hose
The Miflex hose is light weight and extremely flexible. The multi-layer construction shows excellent abrasion resistance and allows for a longer lifespan found in traditional hoses. This kink resistant hose offers a burst resistance twice that of traditional hoses. The Miflex hose is certified to EN250 standards.

TECNOLOGÍA

Placa recubierta de teflón
La placa recubierta de teflón previene la “boca seca”. Se forma condensación en la placa cerámica añadiendo humedad al aire seco liberado por los cilindros scuba.

Ajustador de Resorte con Click
La función de ajustador de resorte con clic es exclusivo de TUSA. Es una perilla ajustable de 5 posiciones diseñada para un mejor control de la resistencia a la respiración.

Capacidad para Agua Fría
La característica de capacidad para agua fría permite que el buceador utilice el regulador en temperaturas del agua por debajo de 50°F/10°C

Primera Etapa con Sello Ambiental
Incluye un diafragma y pistón secundarios que sellan la primera etapa evitando así la contaminación o congelación cuando el regulador se sumerge en el agua contaminada o helada.

Boquilla con Diseño Ortodóncico
La característica de boquilla con diseño ortodóncico evita fatiga en las mandíbulas. Las crestas y materiales flexibles permiten al buceador un mayor control de la boquilla y reduce la tensión en la mandíbula.

Sistema de Escape Secuencial Asistido
El sistema de escape secuencial asistido le otorga al buceador menos resistencia al exhalar debido a su diseño único de escape doble. El buceador experimentara ciclos de respiración más suave reduciendo el consumo de aire y la fatiga.

Ajustador del Flujo Venturi
El ajustador de flujo venturi facilita la respiración al controlar la dirección del aire que circula a través de la boquilla.
