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 L265 can handle many different jobs: · detect the presence of fish below the boat · trigger an alarm when fish are found · measure the depth of the water · set alarms for minimum and maximum depth · show the shape of the bottom · determine whether the seabed is hard or soft We are sure you will find the FishFinder L265 to be one of the most useful devices on your boat.

The transom-mount style, used most often, and in-hull types are shown in Fig. 2-1. All of these transducers measure the water depth. An optional transducer, the Sidelooker, detects objects by looking out to the sides of the boat. Since the transducer is very important to the operation of the FishFinder, it is vital that the transducer be mounted correctly. The transducer will give the most reliable readings if it looks into water which is smooth and undisturbed. If you place the transducer so bubbles or turbulence flow across the face of the unit, the system may give inaccurate readings. There are three important rules when mounting any type of transducer: · The transducer should be continuously covered by water when the boat is moving. (If the transducer is mounted near the side of the boat, it may be exposed when the boat is turning.) The transducer should be placed where turbulence or bubbles will not pass directly over the face of the unit. Don't place the transducer behind any running strakes, intakes, or thru-hull fittings which create turbulence. The transducer should be mounted where it will not be affected by the wash from the propeller(s). · · 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 4 Installation M78990 Transom-mount transducer M78921 Thru-hull transducer M99-141 Fairing for thru-hull transducer M78922 Low profile transducer M78946 In-hull transducer M78930 Sidelooker transducer M78928 Sidelooker transducer for trolling motor Fig. 2-1 Transducer Types particular type of use. In this manual we will include detailed mounting instructions for the transom-mount transducer. We will also include some general information on the other types. For detailed information on these other transducers, see the instructions which are packaged with the unit. Use a transom-mount transducer if ­ . . . your boat has an outboard or inboard-outboard engine(s), and if you're planning to use the Sidelooker option. This type of transducer must be mounted ahead of or beside the propeller(s). Do not use this type of transducer for a boat with a straight-shaft inboard engine. Use a thru-hull transducer if ­ . . . your boat has a straight-shaft inboard engine. This type of transducer is installed in a hole drilled through the hull. Installation 5 Use a low-profile transducer if ­ . . . you want minimum water resistance on a high-performance boat or sailboat. The bottom of the boat must be flat, or have a deadrise angle of no more than 10°. Use an in-hull transducer if ­ . . . you have a high-speed boat or if, for some reason, you cannot use a transom-mount or thru-hull transducer. The hull may be no more than 1" thick. 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. When the installation is complete, the parts snap together as shown. LIKE THIS! Attach the two parts NOT THIS! Bracket is installed upside down Lower the transducer and snap in the release clip Fig. 2-2 Assembling the Transducer Bracket 6 Installation Fig. 2-3 Transducer Mounted on Transom Allow a clearance of at least 10 inches (254 mm) 10" (254 mm) Transducer in released position Fig. 2-4 Transducer Bracket, Side View Positioning the Transom-Mount Transducer Begin by finding the best location for the mounting bracket. Here are the rules: · If your boat has one propeller (outboard or inboard-outboard), mount the transducer about 18" (455 mm) to the side of the centerline of the boat. See Fig. 2-3. Choose the side that is on the downstroke of the propeller. (This is usually the starboard side of the boat.) This will reduce any interference caused by air bubbles. Installation 7 Average transom angle­ no wedge necessary Vertical transom ­ place wedge this way Sloping transom­ place wedge this way 2 to 5 2 to 5 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! 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. The rear of the transducer is too high, creating cavitation. Fig. 2-5 Correct Mounting Position Insert screws 1 and 3 1/4" from the bottom of slots, and screw 2 1/4" from the top of the slot to allow room for adjustment. 1 2 3 Correct alignment If screws are inserted this way, it won't be possible to make the height adjustment. Incorrect alignment Fig. 2-6 Mounting the TransomMount Transducer 8 Installation · · · · · · If the propeller can be turned to steer the boat, allow at least 2" (50 mm) beyond the swing radius of the propeller. This will prevent the propeller from damaging the transducer when it is turned. After installation, check the clearance by turning the wheel so the propeller swings toward the transducer. There should always be a 2" (50 mm) clearance. 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. This may reduce damage by allowing the transducer to flip up if it hits any debris or the bottom. See Fig. 2-4. Allow enough clearance above the transducer so that it can swing upward completely. This is about 10" (254 mm) 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 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 closer to the centerline of the hull. The lower surface of the transducer should tilt down toward the rear at a slight angle (2° to 5°). The mounting bracket includes a wedge. Depending on the angle of the transom on your boat, you may need this wedge to get the correct angle for the bottom of the transducer. Looking at the rear of the boat, be sure the bracket is vertical (perpendicular to the water line). Hold the bracket (and the wedge, if used) against the transom and trace the positions of the screw slots. 2. 3. 4. Installation 9 5. 6. 7. 8. Remove the bracket. See Fig. 2-6. The screws in the outer slots should be placed about 1/4" (6 mm) up from the bottom of each slot. The screw in the center slot should be placed 1/4" (6 mm) down from the top. (This will allow you to adjust the bracket up or down a bit.) Drill pilot holes 3/4" (19.1 mm) deep. Use a 9/64" (3.6 mm) drill bit. To prevent drilling too deeply, wrap masking tape around the drill bit about 7/8" (22 mm) from the tip. Drill in only as far as the tape marker. If you are attaching the bracket to a fiberglass hull, you can minimize any surface cracking of the gel coat. Before drilling each pilot hole, drill a shallow hole (chamfer) at each location about 1/16" (1.5 mm) deep. Use a 1/4" (6 mm) drill bit. Attach the bracket to the hull using the panhead screws with flat washers. Before you tighten the screws, apply a good-quality marine sealant to the pilot holes. This will protect the hull from water penetration. Do not tighten the screws completely yet. 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 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 river banks, or under docks or piers. The M78930 Sidelooker transducer is attached to the same mounting bracket used with the transom-mount transducer. See Fig. 2-7. Begin by installing the transom-mount bracket as described earlier. Remove the two screws and brackets covering the paddlewheel. Attach the Sidelooker transducer to the top of the transom mounting bracket. Use the four panhead screws supplied. The fit should be snug, but do not overtighten the screws. Run the Sidelooker cable beside the depth cable for the transommount transducer. 2. 3. 4. 5. 10 Installation Fig. 2-7 Installing the Sidelooker Transducer Installation Notes ­ Thru-Hull Transducer or Low-Profile Transducer The installation process for these two types is almost the same. Detailed instructions for this installation will be included with the transducer. 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 or low profile 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(s) and shaft(s). For small displacement hulls ­ Install near the centerline of the hull and 1/3 of the way forward from the stern. Always install forward of the propeller(s) and shaft(s). For large displacement hulls ­ Install near the centerline of the hull and 1/3 of the way aft from the bow. Always install forward of the propeller(s) and shaft(s). For sailboats ­ Install forward of the leading edge of the keel, to one side and near the centerline of the hull. Installation 11 2. 3. 4. 5. 6. 7. 8. Choose a location where you can easily reach the transducer from inside the boat. This will allow you to service the unit. Allow at least 6" (152 mm) of headroom above the transducer. When choosing a mounting location, drill a small pilot hole (1/8" or 3.2 mm) from the inside of the hull. Before you drill the hole, be sure you will be able to reach the large nut on the top of the unit, and that there will be enough clearance for the cable. If there is a strake or other feature on the hull, drill from the outside of the hull instead. (This small hole can be filled easily if the mounting location is not suitable.) The position of the transducer is especially critical on high speed boats (capable of more than 20 knots). Check the locations of the transducers on similar boats before installing the transducer in your own boat. Choose the location which will offer the best performance. If the bottom of the hull at the mounting location is flat, you can mount the transducer directly through the hull. If the hull rises at an angle (the "deadrise angle") of more than 10°, you must include a mounting block or "fairing." The transducer must be mounted in a vertical position. Attach the fairing block to the hull as firmly as possible. This fairing block must be able to resist the drag of the water against the hull, and must also be completely waterproof. 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. Do not hang the transducer from the cable. It is very important to seal the opening around the transducer using a high-quality marine sealant suitable for underwater use. After installation, do not leave your boat in the water for any amount of time without checking for leaks. 12 Installation Installation Notes ­ In-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. Choose the best mounting location: For outboard powerboats ­ Install as far aft as possible For inboard/outboard powerboats ­ Install close to the engine(s) For inboard powerboats ­ Install forward of the propeller(s) and shaft(s) For sailboats ­ Install near the centerline of the hull and forward of the leading edge of the keel An in-hull transducer may only be installed in a fiberglass hull which is no more than 1" (25 mm) thick. The in-hull transducer may not be installed in wood or aluminum hulls. Use the standard in-hull transducer if it will be installed in a flat part of the hull, or a section with no more than 10° of deadrise. Use the angled in-hull transducer if the mounting location has up to a 22° of deadrise. Do not try to compensate for the angle of the hull by fairing the epoxy adhesive on the face of the transducer. Use the epoxy supplied with the in-hull transducer, or an equivalent epoxy glue. Do not use any other type of adhesive, including silicone or RTV adhesive. 2. 3. 4. 5. Installation Notes ­ Trolling Motor Transducer Both Downlooker and Sidelooker transducers may be installed on a trolling motor. See Fig. 2-8. 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 to keep these points in mind: 1. 2. 3. Keep the Sidelooker transducer fully submerged. The transducer will only produce an image if it is immersed in water. Keep the Sidelooker transducer clear of weeds or debris. When the position of the trolling motor is changed, the field of view of the Sidelooker also changes. The Sidelooker can be aimed at interesting echoes, but can also be positioned so that it is looking back at the hull. Be aware of the position of the Sidelooker transducer. Installation 13 Fig. 2-8 Installing the Sidelooker Transducer on a Trolling Motor Mounting the Display Unit ­ Standard Mount You may mount the display unit on any flat surface using the bracket supplied. See Fig. 2-9. (There is also an optional kit which allows you to flush-mount the display in a flat panel or dashboard). Follow these instructions if you are using the standard mounting bracket: 1. The "LCD" type display used on this unit is easier to see from certain angles. Before selecting a permanent mounting location, make temporary power connections and turn on the unit. This will allow you to test the visibility of the display from several different angles. Remove the display unit from the bracket by pressing on the large button in the center of the bracket. See Fig. 2-9. Mount the base of the bracket using the supplied screws. Slide the display unit back into the bracket. Adjust the display unit for the best viewing angle. You can turn the display from side to side, and tilt it up or down. 2. 3. 4. 5. 14 Installation Raymarine PWR 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. The display can be turned from side to side. PAGE SETUP CLEAR FISHFIND 265 L265 ER The angle of the display can be changed. Fig. 2-9 Installation on Bracket Dismounting the Display Unit See Fig. 2-9. To release the display from the bracket, press and hold down the left and right sides. You will hear an audible "click," and the bracket will slide out. Mounting the Display Unit ­ Flush Mount In order to do this installation, you will need the optional flush mounting kit (part no. M78931). See Fig. 2-11. 1. Select a mounting location on the dashboard or control panel. Choose a clear, flat area at least 6" x 6" (152 mm x 152 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. Be sure there are no hidden electrical wires or other items behind the point where you plan to mount the display unit. A mounting template is supplied with the flush mounting kit. Tape this over the selected location on the panel and trace around the edges. Make the cutout for the display. Drill a series of 1/2" (13 mm) holes at the points shown around the edges of the cutout area. 2. 3.

Separate the display unit from the mounting bracket. (See Fig. 2-12.) 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. Screw the threaded studs into the holes on the rear of the display unit. Set the display unit into place to be sure that it will fit correctly. Thread the wing-nuts onto the threaded studs to hold the display unit in place temporarily. Install the DC power wiring as described later in this section. Finally, finish the installation. Hold the gasket in place around the opening. Fit the display unit into the cutout. From the rear, screw the thumbscrews securely onto the threaded studs to hold the unit in place. Installing the Transducer Cable A 20 foot length of cable, with the connector attached, is supplied with the transducer. During the installation, do not cut the transducer cable or remove the connector. Do not try to shorten or splice the cable. The transducer cable includes several wires, along with shielding and insulation. If the cable is cut, it cannot be repaired. (Cutting the cable will also void the warranty.) During installation, if you need to drill any holes for the cable, they must be large enough to accept the connector. This will allow you to make the installation without cutting the wire. 1. Route the cable up and over the top edge of the transom. See Fig. 213. 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. (Remember ­ this hole must be large enough to accept the cable with the connector attached. Do not cut the cable!) To seal the opening, use a feed-thru cap where the cable passes through the transom. Run the cable through the interior of the boat. If the transducer cable runs near another electrical wire, it may pick up electrical interference or "noise." To reduce this, try to keep the transducer cable separated 2. 18 Installation 3. 4. 5. as far as possible from all other wires. This is especially important with wiring for the boat's ignition, alternator, or tachometer. Also try to keep the transducer cable away from the antenna and power cables for VHF or FM radios. 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. Be careful not to tear the cable jacket when passing it through bulkheads and other parts of your boat. Secure the cables in place using tywraps or lacing twine. Coil the extra cable and tie it out of the way. If the 20 foot (6 m) transducer cable is not long enough, a 15 foot (4.6 m) extension cable is available from your Raymarine dealer (part no. M99-140). 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. Note: To extend both depth and Sidelooker cables, use the M99-139 extension cable. At the rear of the display unit, plug in the transducer cable using the keyed connector.

If the installation includes the optional Sidelooker transducer, there will be two transducer cables. See Fig. 2-14. The cable from the Sidelooker includes a "Y" connector. Plug the cable from the depth transducer into the open end of the "Y" connector. 2. If extending this cable only, use the M99-140 cable. If adding an extension here, use the M99-139 cable. Sidelooker transducer Depth transducer Fig. 2-14 Cable for Sidelooker Transducer Making the DC Power Connections 1. The display unit is designed for use on boats with 12V DC power systems. (The unit can operate as long as the DC voltage is between 11.0 and 16V DC.) The display unit can be wired to a negativeground system, or both the negative and positive supply lines may be "floating" above ground. This unit is not intended for use on boats with positive ground. The 5-foot power cable (1.5 m) supplied with the display unit should reach the source of DC power. On a small boat, connect the power 2. 20 Installation 3. 4. 5. 6. leads directly to the main battery isolation switch or breaker. On a larger boat, route the power leads to the DC power distribution panel. It is very important that you connect the power leads correctly. See Fig. 2-15. At the power source, connect the red wire to the positive terminal (+), and the black wire to the negative terminal (-). 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. (In-line fuses are available at most marine supply stores.) To prevent any interference or electrical noise, separate the FishFinder power wiring as much as possible from other devices. Avoid running the FishFinder power wires near the power wiring for any radar, radio, or Loran-C units. If possible, wire the FishFinder power wires to a separate circuit breaker. If you need to extend the power wiring by more than 10 feet, use a larger wire size. This will allow the wires to deliver the correct voltage in spite of the longer wire distance. For runs of 20 to 35 feet, use #14 AWG. DC 12V connector to battery T/D connector to transducer RED BLACK DC 12V Fig. 2-15 DC Power Connections Installation 21 7. 8. If you extend the power wiring, be sure all electrical connections are solid and durable. Soldering is the best way to make these connections. Insulate all connections using heat-shrink tubing or electrical tape. You may also use crimp connectors or a terminal strip, but be sure to use good-quality marine-grade parts. At the rear of the display unit, plug in the power wires using the keyed connector. 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. Final note: After you finish the installation, please remember to fill out the Warranty Card included with this manual. 22 Installation 3 ­ Operating Instructions In this section of the manual, we will explain how to operate the unit. (Setup instructions are included in the next section.) Below is a drawing of the display unit. Raymarine PWR Power button Page control pad PAGE Display area Set-up button SETUP Clear button CLEAR FISHFINDER L265 Fig. 3-1 Display Panel Controls on Display Unit The FishFinder is designed to be easy to use while the boat is moving. You can steady your hand by gripping the right side of the display with the fingers of your right hand. This will allow you to use your right thumb to press the buttons on the display. Notice that some of the buttons can be used in two ways. They do one job during a normal display, and a different job when you are setting up the unit. In this section, we will use the symbols PWR , SETUP and CLEAR to indicate the power, setup and clear buttons. PWR This button turns the power on and off. To turn on the power ­ Press once to turn the power on. To enter the Lamp/Contrast menu ­ Press PWR quickly at any time to enter the "Lamp/Contrast" menu. To turn off the power ­ If you press and hold the button, Operating Instructions 23 the display will say "Powering Off." If you hold the button for more than 3 seconds, the display unit will switch off. Page control pad Up and down arrows ­ ( and ) During setup ­ Use these controls to call up a choice or move to the next line on a menu. If the Zoom display is turned on ­ If the manual zoom feature is turned on, these will move the zoom display up or down. < Left and right arrows ­ (< and >) During normal display ­ Use these buttons to go to the next display. During setup ­ Use these arrows to make a choice within a line on the menu. SETUP To enter the Setup Menu ­ Press SETUP at any time. To go to the System Setup display ­ Press this button twice. During normal display ­ When an alarm is triggered, use CLR to turn off the buzzer. (The alarm will continue). During setup ­ Once you make a change, press CLEAR to save the change and go back to the normal display. < CLEAR Turning the Power On and Off Press the PWR button once to turn on the power. For a few seconds, the Lamp/Contrast Menu will appear and the panel light will flash on and off. The light will help you to set up the display in the dark. To turn the power off, press and hold the seconds. PWR button for more than 3 Setup Memory When you first turn on the power, the unit will be prepared to operate using a number of preset values. These "default" values are stored in the unit at the factory. (The default values are listed in Section 4.) 24 Operating Instructions This unit has a memory for some of the settings ­ range, sensitivity, zoom, and frequency. (We will explain these in a moment.) When you turn off the power, any changes you make to these settings will be saved. You can return all of the settings to the factory default values, and reset the trip log to zero. To reset the unit, turn it on by pressing the PWR and CLEAR buttons at the same time. Lamp/Contrast Menu Turn lamp on or off Adjust contrast Fig. 3-2 Lamp/Contrast Menu Press PWR The Lamp/Contrast Menu appears when you first press the PWR button and turn on the power. (You will be able to see part of the main FishFinder display behind the Lamp/ Contrast menu.) You can press the PWR button a second time to exit from the Lamp/Contrast menu and go directly to the FishFinder mode. (If you do not make any changes to the settings within 7 seconds, the unit automatically exits from the Lamp/Contrast menu anyway.) You can also enter the Lamp/Contrast menu from any of the other displays by pressing the PWR button for a moment. Turn on lamp The display unit includes a backlight which allows you to read it at night. If you want to turn on the lamp, use either the < or > arrows on the Page control pad. Operating Instructions 25 Fig. 3-3 Selecting Display Pages Lamp/Contrast menu FishFinder page Zoom page A-Scope page Digital page Sidelooker page Note: This will appear only if the Sidelooker feature is turned on. Return to FishFinder page 26 Operating Instructions Adjust contrast You can also adjust the "contrast" of the display. This is a measure of how light or dark the display appears. Use the control to move from the line for "Lamp On/Off" to the line for "Contrast." Use the < or > controls to adjust the contrast. (The FishFinder unit has a feature which adjusts the contrast automatically to compensate for changes in air temperature.) Save settings When the settings on this display are correct, press the CLEAR button to save the settings and go to the FishFinder page. < Operating Pages This unit has 5 "pages" or normal displays. These can be used to show different kinds of information. Here is a list of the modes: Mode FishFinder page Zoom page A-Scope page Digital page Sidelooker page (using optional Sidelooker transducer) Function Standard operating mode, good general coverage of bottom. Magnified view of smaller section of bottom. Detailed view of area under transducer. See page page 28 page 37 page 39 Numerical display of depth page 41 View of either side of centerline of boat, (used only with Sidelooker transducer) page 42 You can step from one of these pages or displays to another using the < and > arrows on the Page control pad. See Fig. 3-3. There are two other kinds of displays you can see here: · · The system includes several setup displays which can be used to change some of the controls used by the unit. See Section 4. When the Simulator Mode is switched on, the unit generates its own display without receiving signals from the transducer. This mode is used for sales and training. Operating Instructions 27 FishFinder Page Auto sensitivity on Auto features on Transducer frequency Auto range on Auto zoom on Fish symbol on Boat symbol Water surface Depth markers Bottom indication Fish depth Fish symbol Range Buzzer symbol Fish alarm set Deep alarm set Shallow alarm set Bottom depth Fig. 3-4 FishFinder Page A moment after you first turn on the display unit, the Lamp/Contrast menu disappears. The unit then automatically switches to the FishFinder page. Figure 3-4 shows a typical display. (The FishFinder page is also called the "chart" or "bottom graph" display.) As time passes, this display scrolls from right to left. The scrolling image becomes a record of the echoes and the bottom seen by the FishFinder as your boat moves. The images at the right side of the display show the most recent echoes. 28 Operating Instructions Some of these echoes indicate fish, and others show the bottom. As new echoes are received, the FishFinder "draws" a graph of the bottom. The bottom graph helps you to tell whether the bottom is rising or falling. It also allows you to identify the shape or "structure" of the bottom. This can indicate a reef or shipwreck. Notice that the scrolling speed of the display does not necessarily match the speed of the boat. The scrolling speed of the display is called the "chart speed." You can adjust this using the "System Setup Display." (See Section 4.) Many of the items on this display appear in the other modes. Since you are likely to use the FishFinder page most often, we will explain all of these items here. Top of display 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.) Auto range on (R) The "range" is the maximum depth the unit is set to measure. When the auto range feature is on, the FishFinder chooses the correct range setting automatically. Transducer frequency The transducer can use two frequencies - 50 kHz for wide coverage, or 200 kHz for a detailed view. You can also set the unit to use both frequencies at the same time ("dual frequency"). (For more on this, see "Choosing the Frequency.") Auto sensitivity on (S) The "sensitivity" controls the ability of the unit to tell the difference between echoes of different strengths. A higher sensitivity setting makes it easier to see smaller fish, but also may pick up background noise. When auto sensitivity is on, the FishFinder chooses the correct sensitivity setting automatically. Operating Instructions 29 Auto zoom on (Z) The "zoom" can be used to magnify the image from a small section of the water below the boat. (This is used with the Zoom display, which we will describe in a moment.) When the auto zoom feature is on, the FishFinder automatically moves the zoom window up or down to track the bottom. Fish symbol on When the FishFinder sees a fish, it can show this by displaying a fish symbol. When the fish symbol feature is turned off, the FishFinder indicates a fish as an archshaped line on the display. For more information, see the section on "Fish Indications." 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. Center of display Water surface This symbol ("0") shows the depth indicated by the top of the display. Usually, this is the level of the surface of the water. (If the Zoom feature is turned on, this will show the depth of the top of the zoom area.) The depth is shown using the same units as the rest of the display. This could be feet (FT), fathoms (FA), or meters (M), depending on the setting you make in the System Setup display. Depth markers These markers show depths between the surface and the full depth range. In this example, the unit is set for a depth range of 100 feet. This means that each of the depth markers shows an interval of 20 feet. 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.") 30 Operating Instructions If the fish is detected using the narrow 200 kHz beam, the display will show a filled-in symbol. If the fish is detected by the wide 50 kHz beam, the display will use a hollow symbol. (For more on this, see "Choosing the Frequency.") Fish depth This indicates the depth of the fish shown by the fish symbol. This number will be shown using the same depth units (feet, fathoms, or meters) you have selected on the System Setup display. The fish depth indicator is turned off when the fish symbol function is off. Bottom of display Bottom indication This shows the bottom of the lake or sea. You can compare this to the range depth shown in the lower right-hand corner. (In this example, the checkered pattern shows the unit is getting a strong echo return from the bottom. See the information on the White Line feature in the Setup Instructions.) Range The "range" is the maximum depth the unit is set to measure. In this example, this is 100 feet. You can set the range manually, or the FishFinder can do it automatically. Bottom depth This is the depth of the bottom shown on the display. You can select FT (feet), FA (fathoms), or M (meters) using the System Setup display. If the FishFinder can't tell how deep the water is, the last known depth flashes on the display. This will continue until the unit can see the bottom again. 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 set, it will always present a flashing symbol on the display. The Buzzer symbol shows whether the alarms will also use the buzzer. If the Buzzer setting in the System Setup display is on (indicating that the buzzer is enabled for all of the alarms), this symbol will appear filled. Operating Instructions 31 If the Buzzer setting is off (indicating that the buzzer is disabled for all of the alarms), this symbol will be open. Shallow alarm set You can set an alarm to go off if the boat moves into water which is shallower than a certain depth. If you set this type of alarm, the "S" indicator will appear on the display. If the alarm is triggered, the "S" symbol will flash. If the buzzer has been turned on (in the System Setup display), the buzzer will also sound. To stop the buzzer, press the CLEAR button. The "S" symbol will continue to flash until you move into deeper water. Deep alarm set You can set a different alarm to go off if the boat moves into water which is deeper than a certain depth. When this alarm is set, the "D" symbol will appear. If the alarm is triggered, the "D" symbol will flash. If the buzzer has been turned on (in the System Setup display), the buzzer will also sound. To stop the buzzer, press the CLEAR button. The "D" symbol will continue to flash until you move into shallower water. 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 bottom of the display. If the alarm is triggered and the buzzer has been turned on (in the System Setup display), the buzzer will sound for a moment. Before we explain the other pages, there are some general things you should know about the operation of the FishFinder. 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. Raymarine uses these two frequencies because each is better for a particular purpose. 32 Operating Instructions 50 kHz frequency · Scans a wide area · Penetrates water well, good for deep water 200 · · · kHz frequency Scans a narrower area, but produces a more detailed view Good for seeing fish near the bottom or fish close together Better for use in very shallow water "Dual" frequency (both 50 kHz and 200 kHz at once) · Has the advantages of both frequencies · Good depth penetration · Good detail in display · Using the "Dual 50 kHz" setting, the display is produced using the signal from the 50 kHz beam, with additional information from the 200 kHz beam. · Using the "Dual 200 kHz" setting, the display is produced using the signal from the 200 kHz beam, with additional information from the 50 kHz beam. If you are using one of the dual frequency settings, you can get some useful information from the fish symbols. If the fish is spotted by the narrow 200 kHz beam, the fish symbol will be black or filled-in. If a fish is detected by the wide 50 kHz beam, the symbol will be hollow. 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 L265 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 finds a fish, it can be indicated by a fish symbol on the display. In general, a larger symbol means a larger fish. This rule is not always true, though. Let's say that there are two fish of the same size: one is close to the surface, and the other is near the bottom. The fish which is close to the surface will have a larger symbol. This is because the fish which is closer returns more of the sound waves back to the FishFinder. Operating Instructions 33 Actually, the sound waves are usually reflected by the air sac near the center of the fish, and not by the body of the fish. The size of this air sac is different for different kinds of fish. This can also affect the size of the 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. An arch-shaped mark on the display usually indicates a fish. Again, a larger arch usually indicates a larger fish. Several arches together show a school of fish. The return from a fish will have a different appearance, depending on the frequency used. If a fish is spotted by the wide 50 kHZ beam, the arch will An arch-shaped image indicates a fish. The same fish appears differently when shown by the 50 kHz or 200 kHz transducer beams. 200 kHz This indicates a group of small fish. 50 kHz This shows a fish detected in sidelooker mode. A shallow arch or horizontal line is generated when the boat is moving slowly or stopped. When the boat is moving very fast, a fish appears as a single vertical line. Fig. 3-5 Fish Indications 34 Operating Instructions be broad. When using the narrower 200 kHz beam, the same fish will produce a narrower arch. The shape of the arch is also affected by the speed of the boat. If you are moving slowly, the arches tend to be longer. If the boat is moving more quickly, the arches are short and peaked. If the boat is moving very fast, a fish may be indicated by a single vertical line. Bottom Indications The bottom usually produces a strong echo, so it is easy for the FishFinder to see a lot of detail. The FishFinder can indicate many different kinds of bottom conditions. See Fig. 3-6. A hard bottom appears as a thin line. A softer bottom or a bottom covered with seaweed will produce a wide line, as the sound waves reflect from different layers of the bottom. An uneven bottom which is covered with rocks or coral produces a complex display like that shown in the last part of the Figure. The bottom image is irregular, with long "tails" pointing upward. A wreck produces a similar image. When the White Line feature is turned on, the unit can display even more information about the bottom. In Fig. 3-4, the FishFinder is getting a good Hard (Sand) Soft (Mud) Rocks Fig. 3-6 Bottom Conditions Operating Instructions 35 echo from the bottom, so the upper layer of the bottom is shown in a checkerboard pattern. Notice that the lower layer of the bottom is shown as a solid display. This indicates a weaker echo. Sometimes this means that the upper layer of the bottom is soft. Some of the sound waves may 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 bottom, bouncing off of the bottom of the boat, then reflecting off the bottom again. This can happen if the water is shallow, the bottom is hard, or the sensitivity is set to a high value. Performance Modes This unit has two "performance" modes which can be used to add to the standard FishFinder Page. These are the Zoom and the A-Scope Modes. Each presents the raw information from the transducers in a special way. To display one of these modes, press the Page key on the unit. See Fig. 3-3. 36 Operating Instructions Zoom Page Press Zoom display (magnified) Normal display Top of zoom area Line indicates zoom area Zoom magnification Bottom of zoom area Fig. 3-7 Zoom Page The Zoom page gives you a way of enlarging or magnifying a part of the display area. See Fig. 3-7. (The "zoomed" display is actually larger only in the vertical direction.) The right side of the display shows the same information as the FishFinder page. The left side shows the magnified view. In each case, the new information appears at the right edge of the display, and moves to the left. Many of the items on the Zoom page are the same as those on the FishFinder page. There are a few new items. Operating Instructions 37 Zoom magnification This indicates the amount of "zoom" or magnification. You always set the amount of zoom manually, using one of the functions on the Setup display. You can choose an x2 view (double the normal display size), x4, x6 or x8 in the series of setup screens. See Section 4. You must also select the area or "window" of the water you want to zoom. See the next item. Zoom area When you turn on the zoom feature, it can only enlarge a part of the FishFinder display. You must decide which part you want to enlarge. As we said, the right side of the display shows the normal FishFinder display. The vertical line at the right edge of this display shows the area or "window" of the water being enlarged. When the FishFinder is set for auto zoom, it will choose the zoom area automatically. The unit always chooses an area of the water which includes the bottom. The unit then moves this area up or down to keep the bottom in the picture. The auto zoom feature is great for bottom fishing. You may also set the zoom area manually. In the series of setup screens, select manual zoom. (See Section 4.) Once you are back to the zoom display, you can move the zoom area up or down (using the and arrows on the Page control pad) to enlarge any selected "window." To move to the next display, press the > arrow on the Page control pad. < < 38 Operating Instructions A-Scope (Bottom Coverage) Page Press Normal display A-Scope display A-Scope image (real time image) Fish indication Bottom coverage Fig. 3-8 A-Scope Page
