Echo Sounding How it Works ◆ Your eyes underwater An “echo sounder” or “sonar” unit sends high-frequency sound waves down into the water below a boat. These sounds hit the bottom of the lake or sea and bounce back. The display unit measures the time delay as the signal goes out and returns. The FishFinder uses this information to display a graphic image of the bottom conditions. The system also uses this same principle to detect fish or other objects in the water, and display their size and l

1 – Introduction About the FishFinder 465 The FishFinder 465 is a system that uses sound waves (“sonar”) to detect fish and show the bottom of a lake or sea. The system includes a transducer and a display unit, connected by a cable. The transducer sends high-frequency sound waves down into the water. These sounds strike fish, the bottom, or other objects in the water, and return as echoes. The FishFinder then interprets these echoes and presents a display. The FishFinder 465 can handle many

2 – Installation The installation process has four parts: • Mounting the transducer • Mounting the display unit • Connecting the cables for the transducer and power supply • Calibrating the display unit About the Transducer Several different kinds of transducers can be used with this unit. The transom-mount type is used most often. Other types are shown in Fig. 2- 1. Most transducer types can measure the water depth. Some of the transducers also have two other sensors: a paddle wheel which detec

Use a trolling motor transducer if – you want to attach the transducer to a trolling motor. Use a Sidelooker transducer if – you need a way of searching for fish on either side of the boat. This type of transducer is attached to the bracket of the transom-mount transducer. Assembling the Transducer Bracket Fit together the two parts of the transducer bracket as shown in Fig. 2-2.

• If the boat will be carried on a trailer, be sure the transducer will not hit any rollers, bunks or fittings on the trailer. Mounting the Transom-Mount Transducer 1. On a boat with a fiberglass hull, the leading edge of the transducer should extend 1/8" (3.2 mm) to 1/4" (6 mm) below the bottom edge of the hull. See Fig. 2-5. On an aluminum hull, the transducer should extend a bit more – 1/4" (6 mm) to 3/8" (9 mm). If the boat will be operated at high speeds, the transducer may be mounted close
