Installation Overview

INSTALLATION PREPARATION

display on the control head. It should be installed in contact with the surface of the water in an area that has smooth water flow - usually on the transom of the boat. There are several mounting options for the transducer. Review the following section to determine the method that works for you and your boat.

Determining How to Mount the Transducer

The 250DX includes a model XT-6-20 transducer. This transducer can be mounted on the transom of the boat, or bonded to the inside of a fiberglass hull boat.

The transom installation, which is the
most widely used, places the transducer
on the outside of the boat hull. This
technique produces the least signal loss,
and provides a way to adjust the
transducer after installation. The
mounting hardware included is designed
to protect both the boat and the
transducer should the boat strike debris	Transom Mounted Transducer

in the water or when trailering.

	As an alternative to transom
	mounting, it is possible on many
	fiberglass-hulled boats to glue the
	transducer on the inside of the boat
	hull. Since fiberglass has similar sonar
	characteristics as water, the sonar
	signal can pass through the boat hull
	with minimal loss. The hull of the
	boat must be single layer
	construction (not double-hulled).
	Also, any air trapped in the
	lamination of the fiberglass would
	prevent the sonar signal from passing
