4.2 Transducer Installation

The transducer is crucial for sonar operation. It should be mounted in a location that provides an unobstructed view of the water beneath your boat, free from turbulence or air bubbles. Common mounting locations include the transom, inside the hull, or on a trolling motor.

• Transom Mount: This is the most common method. Ensure the transducer face is submerged and parallel to the waterline.
• Inside-Hull Mount: Suitable for solid fiberglass hulls. The transducer is epoxied to the inside of the hull, shooting through the fiberglass.
• Trolling Motor Mount: Specific brackets are available for mounting on a trolling motor.

Refer to the separate transducer installation guide for detailed instructions specific to your transducer type and boat.

4.3 Power Connection

The HELIX 5 SONAR G2 is battery-powered. Connect the power cable to a 12V DC power source. Ensure the connection is fused and protected from moisture.

1. Connect the red wire to the positive (+) terminal of your 12V battery.
2. Connect the black wire to the negative (-) terminal of your 12V battery.
3. Plug the power cable into the corresponding port on the back of the control head.
