1 – Introduction About the FishFinder L470 The FishFinder L470 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 L470 can handle man

System Components The FishFinder L470 consists of a compact display unit connected to a transducer. The transducer is attached to the boat and extends into the water. Standard Equipment When you unpack your FishFinder L470, you should find the following standard equipment in the carton. If any items are missing, please notify your Raymarine dealer immediately, or contact the Customer Service Department at Raymarine at 1-800-539-5539, ext. 2333. Please provide the serial number of the FishFind

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 style, used most often, and in-hull types are shown in Fig. 2-1. Besides measuring depth, the transducers have two other sensors: a paddle wheel which detects the speed of the boat, and a s

Use a trolling motor transducer if – . . . you want to attach the transducer to a trolling motor. (Not recom- mended for deep water operations.) Use a Sidelooker transducer – . . . for searching for fish or structure on either side of the boat. This type of transducer is attached to the bracket of the transom-mount transducer, or to the shaft of the trolling motor.

Do not mount the transducer behind any hull fittings, intakes, or other parts which extend from the hull. These may cause turbulence or air bubbles. The bracket has a quick-release mechanism.

measured from the bottom of the transom. • If considering the Sidelooker option, look for a mounting location where the Sidelooker array will not be blocked by the engine housing or other mounted hardware. 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 bott

7. Move the bracket up or down so that the leading edge of the trans- ducer has the clearance shown in Fig. 2-5. 8. Once the bracket is in the correct position, you can tighten the screws. Mounting the Optional Sidelooker Transducer - Transom-Mount Installation 1. The Sidelooker transducer allows the display unit to check the water to either side of the boat. This is helpful when you are looking for fish or structure near banks, or under docks or piers. 2. The M78930 Sidelooker transducer is at

Installation Notes – Thru-Hull Transducer Detailed instructions for this installation will be included with the trans- ducer. In this section, we will note just a few important points. 1. Earlier we listed three general rules for placing transducers. All of these rules apply when you are mounting a thru-hull transducer. Here are some other rules for selecting the best mounting location: For planing hulls – Install in the flat planing area near the stern. Always install forward of the propeller

6. If the hull of the boat has a core-type hull, you will need to follow some special mounting procedures. The core material must be protected from any water which may leak from the inside of the boat. (If the core material is allowed to remain wet, it may rot and weaken the hull.) 7. When working with the transducer, support it by holding the body of the unit or the rings. Do not hang the transducer from the cable. 8. It is very important to seal the opening around the transducer using a high

Installation Notes – Trolling Motor Transducers Both Downlooker and Sidelooker transducers may be installed on a trolling motor. See Fig. 2-8. Fig. 2-8 Installing the Sidelooker Transducer on a Trolling Motor Detailed instructions for these installations will be included with the transducer(s). The Downlooker transducer is mounted on the horizontal gear case of the motor. The Sidelooker transducer is attached to the vertical support tube. These installations are simple, but it is important t

Installation Notes – Transducer for Speed and Temperature Only This type of transducer may be used with a thru-hull transducer which reads depth only. The speed/temperature transducer is attached to the transom of the boat. Detailed instructions for this installation will be included with the transducer. The cable for this transducer uses a “Y” connector. See the notes on “Installing the Transducer Cable.” EMC Installation Guidelines When different types of marine electronic equipment are mounte
