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.

  1. TEFLON COATED PLATE TEST- The Teflon Coated Plate prevents “dry mouth.” Condensation forms on the brass plate adding moisture to the dry air released from scuba cylinders.

 

  1. CLICK SPRING ADJUSTMENT- The Click Spring Adjustment feature is exclusive to TUSA. It is a five (5)-position adjustment knob designed to better control breathing resistance.

 

  1. COLD WATER READY- The Cold-Water Ready feature enables the diver to use the regulator in water temperatures below 50° F / 10° C.

 

  1. ENVIROMENTALLY SEALED 1ST STAGE- The use of a secondary diaphragm and piston sealing the 1st stage preventing contamination or freezing when the regulator is submersed in contaminated or freezing water.

 

  1. ORTHO-CONSCIOUS MOUTHPIECE- The Ortho-Conscious Mouthpiece feature prevents jaw fatigue. The ridges and flexible material allow the diver to have more control of the mouthpiece and reduces tension in the jaw.

 

  1. SEQUENCE EXHAUST ASSIST SYSTEM- The Sequence Exhaust Assist System gives the diver less resistance when exhaling due to its unique double exhaust design. The diver experiences smooth breathing cycles reducing air consumption and fatigue.

 

  1. VENTURI FLOW ADJUSTMENT- The Venturi Flow Adjustment allows for ease of breathing by controlling the direction of air through the mouthpiece.
