Technology
Venturi Flow Adjustment:
Allows for ease of breathing by controlling the direction of air through the mouthpiece.
Environmentally 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.
Cold Water Ready:
This feature enables the diver to use the regulator in water temperatures below 50 degrees F/10 degrees C.
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.
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.
Ortho-Conscious Mouth Piece:
The ridges and flexible material allow the diver to have more control of the mouth piece and reduces tension in the jaw. It prevents jaw fatigue.
Click Spring Adjustment:
This is a feature exclusive to TUSA. It is a five position adjustment knob designed to better control breathing resistance.
