TRANSDUCER INSTALLATION

There are two different installation methods for your transducer:

•Transom Transducer

•Trolling Motor Transducer.

Find the section that describes the method of installation you will be using.

The Side Imaging transducer has some special requirements because of its side viewing capabilities:

•The Side Imaging transducer must NOT have anything obstructing the ‘view’ of the side looking beams, i.e. nothing can be in the line of sight of these beams (not a hull, motor, or other transducer, etc).

NOTE: You may need to tilt the motor up and out of the way when using the side looking beams.

•In order for the side beams to be displayed accurately, the transducer must be mounted so that it is looking straight down in the water when the boat is in the water.

		Transducer Position
	Correct transducer position	Incorrect transducer position,
	Correct transducer position	interfering with the side beams
		interfering with the side beams

Motor Position

	Motor is far enough forward	Motor is not far enough forward,
	Motor is far enough forward	interfering with the side beams
		interfering with the side beams
