The adjustable knob designed to better control breathing resistance.
The advanced flow system allows ease of air flow
and makes air delivery smoother due to the curved housing structure.
The Teflon Coated Plate prevents “dry mouth.” Condensation forms on the brass plate adding moisture to the dry air released from scuba cylinders.
The click spring adjustment feature is exclusive to TUSA. It is a 5 position adjustment knob designed to better control breathing resistance.
The cold water ready feature enables the diver to use the regulator in water temperatures below 50°F/10°C.
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.
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.
A balance chamber added to the regulator 2nd stage, providing equal pressure to both sides of the LP seat greatly reducing inhalation effort.
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.
The swivel hose gives maneuverability to the 2nd stage. The hose can rotate 360 degrees allowing it to move freely with the diver’s head motions.
The venturi flow adjustment allows for ease of breathing by controlling the direction of air through the mouthpiece.
The IR-3 is a second stage regulator and a power inflator combination.
