Technology :

• 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.
• 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.
• Cold Water Ready : The Cold Water Ready feature enables the diver to use the regulator in water temperatures below 50° F / 10° C.
• 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.
• Ortho Conscious Mouthpiece : The Ortho-Conscious Mouth Piece feature prevents jaw fatigue. The ridges and flexible material allow the diver to have more control of the mouth piece and reduces tension in the jaw.
• 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.
• Venturi Flow Adjustment : The Venturi Flow Adjustment allows for ease of breathing by controlling the direction of air through the mouthpiece.
