Humminbird 405SX manual Installation Overview, Determining How to Mount the Transducer

Transom Mounted Transducer

INSTALLATION PREPARATION

INSTALLATION OVERVIEW

The transducer converts electrical energy from the transmitter into mechanical pulses or sound waves. The transducer also receives the reflected sound waves and converts them back into electrical signals for 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 405SX includes a model XT-6-24 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 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
