Additional information

Regulator Type

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 First 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 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.

 

 

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.

 

 

Ventury Flow Adjustment

The Venturi Flow Adjustment allows for ease of breathing by controlling the direction of air through the mouthpiece.
