Key Benefits

Advanced Flow System - The Advanced Flow System allows ease of air flow and makes air delivery smoother due to the curved housing structure.

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

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.

Ortho-Concious Mouth Piece - 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.

Pneumatically Balanced 2ND Stage - A balance chamber added to the regulator 2nd stage, providing equal pressure to both sides of the LP seat greatly reducing inhalation effort.
