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.
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.
Description Sidelooker transom-mount transducer Sidelooker transducer for trolling motor mounting. Companion with M78928 downlooker depth/temp transducer, with 12 ft. (3.6 m) cable and hardware Part No. M78930 M78929 Extension cable, 5 pin (15 ft., 4.5 m) Extension cable, 9 pin (15 ft., 4.
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 transommount style, used most often, and in-hull types are shown in Fig. 2-1.
M78898 Transom-mount transducer M78946 In-hull transducer M78923 Thru-hull transducer M78930 Sidelooker transducer for transom mount M99-142 Fairing for thru-hull transducer M78929 Sidelooker transducer for trolling motor Fig. 2-1 Transducer Types Selecting the Correct Type of Transducer Before you begin the installation, double-check to be sure you have the correct type of transducer. Each kind of transducer is designed for a particular type of use.
Use a trolling motor transducer if – . . . you want to attach the transducer to a trolling motor. (Not recommended 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. Assembling the Transducer Bracket Fit together the two parts of the transducer bracket as shown in Fig. 2-2.
Fig. 2-3 Transducer Mounted on Transom Allow a clearance of at least 10 inches (254 mm) Transducer in released position 10" (254 mm) Fig. 2-4 Transducer Bracket, Side View • • • If your boat has twin propellers (outboard or inboard-outboard), place the transducer near the centerline of the boat. 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.
Average transom angle– no wedge necessary Vertical transom – place wedge this way 2 to 5 2 to 5 Sloping transom– place wedge this way 2 to 5 For fiberglass hull – 1/8" to 1/4" (3.2 to 6 mm) For aluminum hull – 1/4" to 3/8" (6 to 9 mm) No! No! The bow of the transducer is above the bottom of the transom, creating cavitation. Rivets on the hull are creating bubbles. Lower the transducer a bit. No! The rear of the transducer is too high, creating cavitation. Fig.
• • 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. 2. 3. 4. 5. 6. On a boat with a fiberglass hull, the leading edge of the transducer should extend 1/8" (3.
7. 8. Move the bracket up or down so that the leading edge of the transducer has the clearance shown in Fig. 2-5. Once the bracket is in the correct position, you can tighten the screws. Mounting the Optional Sidelooker Transducer Transom-Mount Installation 1. 2. 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.
Installation Notes – Thru-Hull Transducer Detailed instructions for this installation will be included with the transducer. In this section, we will note just a few important points. 1. 2. 3. 4. 5. 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.
6. 7. 8. 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.) 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.
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.
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.
• • transducer cable separated as far as possible from all other wires. This is especially important with wiring for the boat’s ignition, alternator, or tachometer. It is also helpful to keep the transducer cable away from the FishFinder power cable. If it is necessary to run the transducer cable across any wires, make the crossing at a right angle. Use only genuine Raymarine cables. During the installation, do not cut the transducer cable or remove the connector.
To release the display from the base, press on the right and left sides until you hear the clicks. Slide the display out of the bracket.

Mounting the Display Unit – Flush Mount In order to do this installation, you will need the optional flush mounting kit (part no. M99-138). See Fig. 2-12. 1. 2. 3. 4. 5. Select a mounting location on the dashboard or control panel. Choose a clear, flat area at least 7" x 7" (180 mm x 180 mm). Be sure you will also have at least 6" (152 mm) of clearance behind the area where the display unit will be mounted. It is a good idea to drill a small pilot hole in the center of the mounting area.
6. Separate the display unit from the mounting bracket. (See Fig. 2-13.) Press the large button in the center of the bracket to separate the bracket arms. The display unit is attached to the arms by two screws. Each screw is covered by a cap. Locate the small slot beside each cap and pry upward using a small screwdriver. Remove the caps, then the two screws and the two wave washers. Save these parts in case you ever want to use the mounting bracket.

See Fig. 2-14. Secure the cable using cable clamps. (These clamps are available from your local marine equipment supplier.) If you do not want to expose the cable on the deck, you may drill a new hole (3/4" or 19 mm) through the transom for the cable.
5. When you attach the extension cable, be sure that the connections are tight and watertight. Use Dow Corning DC-4 or an equivalent sealing compound to protect the connector assemblies. At the rear of the display unit, plug in the transducer cable using the keyed connector. Installing the Transducer Cable – Sidelooker Option 1. 2. If the installation includes the optional Sidelooker transducer, there will be two transducer cables. See Fig. 2-15.
2. Plug the cable from the depth-only transducer into the receptacle connector on the optional speed- and temperature-only transducer. The speed- and temperature-only transducer then connects at the transducer receptacle of the FishFinder L470. This is shown below in Fig. 2-16. Sensor for speed and temperature Sensor for depth only Fig. 2-16 Cable for Speed and Temperature Sensor Making the DC Power Connections 1. 2. 3. 22 The display unit is designed for use on boats with 12V DC power systems.

The negative terminal may also be called “ground” or “earth.” (The display unit is internally protected if you accidentally reverse the polarity of the power wires.) Attach the red or positive wire to a 5 amp circuit breaker. If the unit is connected directly to the boat’s battery, include a 2 amp in-line fuse.
Note – Press firmly when inserting the power cable and transducer cable to ensure a tight seal. 8. When you press the PWR button, the display unit should turn on. If the unit will not turn on and you suspect that you may have reversed the power connections, check the DC power lines all the way back to the battery. If the polarity is not correct, reconnect the leads properly and try again.
4. higher value for Speed Cal. If the display unit is reading high, use a smaller number for Speed Cal. You may enter any value between 75 and 125. The temperature sensor is usually very accurate, but you can adjust the calibration using the entry for “Temp Cal.” Final note: After you finish the installation, please remember to fill out the Warranty Card included with this manual.

“chart speed.” You can adjust this using the “Setup Menu.” (See Section 4.) Many of the items on this display appear in the other display pages. Since you are likely to use the FishFinder Page most often, we will explain all of these items here. Top of display Buzzer symbol This symbol shows whether any of the alarms will use the buzzer. There are three kinds of alarms: shallow, deep, and fish. If one of these alarms is triggered, the unit will present a flashing symbol on the display.
Fish alarm set The FishFinder also has an alarm which will sound whenever it detects a fish. When this alarm is set, the fish symbol appears at the top of the display. If the alarm is triggered and the buzzer has been turned on (in the System Setup Menu), the buzzer will sound for a moment. Auto features on (AUTO) If any of the automatic features are turned on, the “Auto” indication will appear here. (These include the automatic range, auto sensitivity, and auto zoom features.
the unit to use both frequencies at the same time (“dual frequency”), or even display both frequencies at once (“split screen”). Auto frequency on (A) An “A” indication here shows that the unit is choosing the frequency automatically. (For more on this, see “Choosing the Frequency.”) Boat symbol This symbol is always turned on. It indicates that the new information appears at the right edge of the display, and the older information moves toward the left.
From the System Setup Menu, you can turn this item off or change the units used for this display. Fish symbol This indicates that the FishFinder sees a fish. Generally, the larger the fish symbol appears, the larger the fish. (The size of the fish symbol actually depends on a number of factors. See the section on “Fish Indications.”) If the fish is detected using the narrow 200 kHz beam, the display will show a filled-in symbol.
Choosing a Frequency We said that the FishFinder uses sound waves to “see” through the water under the boat. The “frequency” is a measure of how fast the sound waves change or “vibrate.” The FishFinder uses sound waves with two different frequencies – 50 kHz and 200 kHz.
Fish Indications Even using advanced sonar technology, it is sometimes hard to detect a fish in the water. The body of a fish is just a little more dense than the surrounding water. There is really nothing very solid for the sound waves to bounce off of. The FishFinder L470 is very good at telling the difference between a fish and the surrounding water. In fact, Raymarine is the leader in this technology. When the FishFinder detects a fish, it can be indicated by a fish symbol on the display.
fish symbols on the display. A fish with a large air sac will produce a large fish symbol, while a fish with a small sac will produce a small symbol. The symbol also indicates which of the two frequencies was used to locate the fish. If the fish was spotted by the wide 50 kHz beam, the symbol will appear to be hollow. If the fish was detected by the narrow 200 kHz beam, the symbol will be solid. If the fish symbol feature is turned off, the FishFinder indicates fish in a different way. See Fig. 3-5.
Hard (Sand) Soft (Mud) Rocks Fig. 3-6 Bottom Conditions reach through this layer, and may be reflected by a more solid layer below. It is also possible that the sound waves are making two complete trips – hitting the seabed, bouncing off of the bottom of the boat, then reflecting off the seabed again. This can happen if the water is shallow, the seabed is hard, or the sensitivity is set to a high value.
Window Page Fig. 3-7 Window Page The Window Page is a flexible feature which allows you to combine several different kinds of information on the display of the unit. See Fig. 3-7. The right side of the Window Page is a half-screen version of the FishFinder Page. All of the features of the full-screen FishFinder Page are available, including Zoom, A-Scope, and Bottom Lock. The fishfinder features of the Window page operate identically to those in the FishFinder Page.

The digital displays in Window options A, B, C, D, and E all behave identically to the corresponding ones in the full-screen Digital Page (see page 47). The sidelooker displays in Window options F, G, and H all behave identically to those in the full-screen Sidelooker Page (see page 44). These options will only be displayed if the Sidelooker feature is enabled. Sidelooker Page Transducer mounted on trolling motor Rock 31° beam Fish Boat Rock Fish Sidelooker transducer Fig.
The optional Sidelooker transducer transmits two acoustic beams—one to the port side of the boat, and one to the starboard. These are displayed on the left and right halves of the Sidelooker Page. See Fig. 3-9. Once the Sidelooker feature has been turned on, you can reach the Sidelooker page easily. Press the < or > buttons on the Page Control Pad until the Sidelooker Page appears. The unit will present a display similar to Fig. 3-10.
Underwater objects such as submerged tree stumps or rocks can also be detected by the Sidelooker transducer. These objects usually appear as thicker vertical targets. The Sidelooker sounding beam is transmitted very close to the surface of the water. In rough or choppy water this turbulence may appear on the Sidelooker display as “noise” or “clutter.” The Sidelooker will also display noise or clutter when your boat travels at high speeds or in very shallow water.

If you have selected feet (FT) or fathoms (FA), the distance shown here will be measured in feet. If you have selected meters (M), the distance shown here will be in meters. Fish indication An arch-shaped mark shows that the unit has detected a fish. In general, a larger arch indicates a larger fish. If the fish symbols are turned on, the unit will indicate fish using these instead.
Digital Page Fig. 3-11 Digital Page The Digital Page presents several measurements at the same time using large, easy-to-read digital numbers.

Performance Modes This unit has three “performance” modes which can be used to add to the standard FishFinder Page. These are the Zoom, A-Scope and Bottom Lock Modes. Each mode presents the raw information from the transducers in a special way. To reach one of these modes, press the corresponding button on the unit. See Fig. 3-12. Zoom Mode Zoom display (magnified) Normal display Top of zoom area Bottom of zoom area Zoom magnification Line indicates zoom area Fig.
Many of the items presented by the Zoom Mode are the same as those on the FishFinder Page. There are a few additional items: Zoom magnification This indicates the amount of “zoom” or magnification. You always set the amount of zoom manually. While the Zoom screen is visible, press SETUP . This will bring you to the Zoom Menu, shown in Fig. 4-10. You can choose an x2 view (double the normal display size), x4, x6 or x8. See Section 4 for details.
A-Scope (Bottom Coverage) Mode Normal display A-Scope display A-Scope image (real time image) Fig. 3-14 Fish indication A-Scope Mode (half screen) Bottom coverage On the FishFinder Page the bottom graph is “drawn” after the FishFinder receives several echoes. This has the effect of showing a record of the bottom contour. The A-scope Mode shows raw sonar data directly from the transducer beam. This gives you a “real time” image of fish and bottom structure directly below the transducer.
create wider lines. Unlike the scrolling FishFinder Page, the A-Scope does not show a history of scans; instead, it is a “real-time” display. The shape of the A-Scope display shows the result as the sonar beam spreads as it penetrates deeper into the water. Bottom coverage The digital number at the bottom of the A-Scope image indicates the bottom coverage. This is the diameter of the sonar beam where it meets the bottom.
Bottom Lock Mode Top and bottom of Bottom Lock range Bottom indication Bottom depth below surface Bar indicates area being displayed Fig. 3-15 Bottom Lock Mode The normal display on the FishFinder is a “top-down” view, as if it was seen from the surface of the water. The Bottom Lock Mode shows a “bottom-up” view. The bottom is used as a reference, and all depths are measured up from the bottom. BOT You can reach the Bottom Lock Mode at any time by pressing the LOCK button.
the selected range, then Bottom Lock will not display the bottom image. Bottom Lock Range The range for the Bottom Lock image is set independently from the master range setting for the FishFinder. This “Bottom Lock Range” is measured up from the bottom, rather than down from the surface. The Bottom Lock Range may be adjusted using the Setup Menu when the Bottom Lock feature is enabled. (See page 73). The current setting for the Bottom Lock Range is shown in the upper right corner of the Bottom Lock image.
4 – Setup Instructions The Setup Menu Press the SETUP button to enter the Setup Menu. The menu items available will change, depending on the display or combinations of displays the unit is presenting when you press SETUP . Figure 4-1 shows the order of the menu items if you start from the normal FishFinder Page.

there is no number next to the bar graph, this tells you that the Sidelooker is being adjusted. From the menu item for the range setting, press the V arrow of the Page Control Pad. The next menu item will allow you to set the sensitivity. See Fig. 4-3. Use the < and > arrows of the Page Control Pad to select Auto or Manual sensitivity. Auto sensitivity The FishFinder can be set to select the sensitivity by itself, automatically.
Chart Speed Setting Most of the displays on the FishFinder show a record of the signals the unit has received. The new information appears at the right (or top) edge of the display. The older information moves toward the left (or bottom) of the display. The “chart speed” adjustment sets the speed at which the display moves. (Notice that the scrolling speed of the display is not related to the speed of the boat over the bottom. The speed of the display is controlled only by the chart speed setting.
Fig. 4-5 Chart Speed Menu Item Chart speed This adjusts the speed at which the information moves across the display. Use the < and > arrows of the Page Control Pad to change the chart speed. Making the bar longer increases the chart speed. If you move the bar all of the way to the left, the FishFinder will “freeze” and hold the current display. (The depth indicator will continue to update.) If you are done with your setup changes, press the CLEAR button to go back to the normal display.
AUTO frequency If the frequency is set to AUTO, one of the two single frequencies (200 or 50 kHz) will be automatically selected, depending on the depth of the bottom. If the bottom is deeper than 350 feet (or 60 fathoms or 100 meters), the unit will use the 50kHz frequency. In shallower water, the unit will use the 200 kHz frequency. MAN (Manual) frequency You can also set the frequency manually.
If you are using one of the dual frequency (or split) selections, some of the fish may appear in the wide 50 kHz beam, but not in the narrower 200 kHz beam. Fish which appear in the narrow 200 kHz beam are located more directly under the transducer, and the symbol will be solid black. Fish which appear in the wider 50 kHz beam are less precisely located, and the symbol will be hollow. If you are done with your setup changes, press the CLEAR button to go back to the normal display.
System Setup Menu Note - The “System Setup Menu” is not the same as the “Setup Menu” described earlier. The “Setup Menu” includes a series of small screens, shown in Fig. 4-1. The “System Setup Menu” is a single display, which includes several different items. See Fig. 4-8 and 4-9. FishFinder Page Setup Menus System Setup Menu Fig.4-8 Reaching the System Setup Menu You can reach the System Setup Menu at any time by pressing SETUP twice. See Fig. 4-8.
< To change one of the items, use the and V arrows of the Page Control Pad to move up or down in the display. This will highlight an area on the display where the unit is ready to make a change. (This is like the “cursor” on a computer.) Once you have moved to the correct line, press the < or > arrows of the Page Control Pad to change the entry. Make your change, then press the CLEAR button to leave the display. The unit will store any changes you have made. Simulator This unit has a built-in simulator.

The image shown in Fig. 3-4 is presented with the White Line feature turned on. “VRM” means “Variable Range Marker.” On this unit, the VRM feature offers a way of finding the depth of an object on the display. When used with the FishFinder Page, the VRM feature creates a horizontal line across the display.
unit says that you are moving faster than you really are, you can adjust the Speed Cal figure to a smaller number. If the unit says that you are moving slower than your actual speed, use a larger number for Speed Cal. The setting can range between 75 and 125. Use the < and > controls to change the value. For more information, see the section on “Calibrating the Sensors.” Temp Cal This unit can display the water temperature.
To turn this feature off, press the < control until the display indicates zero feet, fathoms or meters. When these values are displayed in the Shallow Alarm “pop up” window, you will notice that the menu item in the System Setup Menu will read “Off.” Deep Alarm < An alarm can be set to trigger whenever the boat moves into water which is deeper than a preset limit. Use the and V controls to move to the line for Deep Alarm and use the > control to turn this item on.
operating with dual frequencies, the buzzer will produce two tones—one right after the other. If a fish has been detected by the 200 kHz beam, a high tone will be followed by a lower tone.

5 – Maintenance and Troubleshooting Periodically check the display unit, cable, and transducer. Be sure all components are free of corrosion and are securely mounted. Check all cables for signs of chafing or abrasion. Be sure all of the connections to the boat’s DC power and ground system are clean and tight. Cleaning Instructions Always keep the display unit clean. Use a soft, clean cloth to wipe off the display panel. Do not use abrasive cleansers, chemical cleaners or solvents.
2. 3. 4. will change to the factory defaults. See the default settings on page 82. If the power wiring includes a fuse, it may be blown. Also check the circuit breaker or main battery switch. You may have reversed the power connections. Follow the DC power lines all the way back to the battery. The red wire should connect to the positive terminal (+) on the battery or power source, and the black wire should connect to the negative terminal (-) (also called “ground” or “earth”).
4. The transducer cable may be damaged. Check for any point where the wiring may be pinched or bent. Look for signs that water has gotten into the cable. If the transducer cable is damaged, the transducer and cable should be replaced as a unit. Contact Raymarine for instructions. The display unit does not see the bottom or fish – 1. Be sure the display unit is not using the Simulation mode (If this is the case, the word “Simulation” will flash on the display.) 2.

The transducer may not be aimed straight down. In order to display complete arches, the transducer must be vertical. The sensitivity setting may not be high enough. Go to the Setup Menu, choose Manual Sensitivity, and increase the sensitivity. The display disappears or is unreliable when the boat is moving at high speeds – 1.
The speed or log readings are wrong – 1. The paddle wheel on the transducer may be fouled. Clean the parts as described in the section on “Cleaning Instructions.” 2. Check the speed calibration. Use the item for “Speed Cal” on the System Setup Menu. See the instructions in Section 2. Servicing a Thru-Hull Transducer If your boat has a thru-hull transducer, you can service it without removing the boat from the water. The sensor(s) are mounted in a cylindrical plug in the center of the transducer assembly.
