The FishFinder 265 is a system that uses sound waves ("sonar") to detect
fish and show the bottom of a lake or sea. The system includes a trans-
ducer 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 265 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 265 to be one of the most useful
devices on your boat.

  • Page 9 can swing upward completely. This is about 10" (254 mm) measured from the bottom of the transom. • If the boat will be carried on a trailer, be sure the transducer will not hit any rollers, bunks or fittings on the trailer. On a boat with a fiberglass hull, the leading edge of the transducer should extend 1/8"...
  • Page 10 Move the bracket up or down so that the leading edge of the trans- ducer has the clearance shown in Fig. 2-5. Once the bracket is in the correct position, you can tighten the screws. The Sidelooker transducer allows the display unit to check the water to either side of the boat.
  • Page 11 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. 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.
  • Page 12 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.
  • Page 13 Detailed instructions for this installation will be included with the trans- ducer. This type of transducer is attached to the horizontal gear case of the trolling motor. The installation is simple, but is important to keep the transducer away from the wash from the propeller, and from turbulence caused by parts of the hull.

  • Page 15 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. In order to do this installation, you will need the optional flush mounting kit (part no.
  • Page 16 Remove the template and draw straight lines between the 1/2" holes. Cut along each of the lines with a small saw. Separate the display unit from the mounting bracket. (See Fig. 2-11.) Press the large button in the center of the bracket to separate the bracket arms.
  • Page 17 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.
  • Page 18 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.
  • Page 19 Plug the cable from the depth transducer into the open end of the “Y” connector. The display unit is designed for use on boats with 12V DC power systems. (The unit can operate as long as the actual voltage is between 11.0 and 16V DC.) The display unit can be wired to a negative-ground system, or both the negative and positive supply lines may be “floating”...
  • Page 20 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.

  • Page 27 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.
  • Page 28 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.
  • Page 29 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.
  • Page 30 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”...
  • Page 31 There is really nothing very solid for the sound waves to bounce off of. The FishFinder 265 is very good at telling the difference between a fish and the surrounding water. In fact, Apelco is the leader in this technology.
  • Page 32 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.
  • Page 33 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.
  • Page 34 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.
  • Page 35 Zoom display Normal (magnified) display Top of zoom area Line indicates zoom area Bottom of zoom area Zoom magnification 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.
  • Page 36 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.
  • Page 37 Normal A-Scope display display A-Scope image (real time image) Fish indication Bottom coverage A-Scope Mode Display On the FishFinder display the bottom graph is “drawn” after the FishFinder receives several echoes. This has the effect of showing a record of the bottom contour.
  • Page 38 A-Scope image This shows the beam of sound waves extending down from the boat, and spreading as it moves through the water. Any fish or objects which are positioned under the boat will appear on the display. This is a “real time” display, so you can see the fish symbols moving as the fish swim under the boat.
  • Page 39 Depth Digital Alarms Display The Digital page presents the depth in large numbers on the display. See Fig. 3-9. This display is useful when you are traveling, but not looking for fish or checking the appearance of the bottom. Depth The Digital display reports the depth of the bottom.
  • Page 40 The Sidelooker feature is very helpful for certain kinds of fishing. It allows you to check along the sides of a stream or river. You can also look under the edge of a bank or pier, or into a snag or shallow spot. The Sidelooker page, like the FishFinder page, displays a graph or chart.
  • Page 41 Boat symbol Side range Fish echo Rock Centerline Depth below boat Sidelooker Display the display moves is set by the entry for “chart speed” in the Setup Menu.) New information appears at the top of the display. The Sidelooker transducer transmits at the 200kHz frequency. If the Sidelooker detects fish and the fish symbol function is turned on, solid fish symbols will appear.
  • Page 42 noise or clutter when your boat travels at high speeds. For best results, use the Sidelooker at idle or slow trolling speeds. Here are the special items on this display: Boat symbol This shows that the bow of the boat is aiming forward, toward the top of the display.
  • Page 43 Press the Setup button to enter the Setup Menu. To move from one display to another, press the arrows on the Page control pad. To return to the normal display, press . See Fig. 4-1. This means that you can reach these displays quickly, make a change, then return to the normal display quickly.
  • Page 44 Range Settings If you press once, the first menu item allows you to set the range. SETUP See Fig. 4-2. The range sets the maximum depth the unit will be able to see. Use the < and > arrows on the Page control pad to select Auto or Manual range.
  • Page 45 Sensitivity Setting This adjusts the ability of the unit to tell the differences between echoes of different strengths. In general, the sensitivity should be as high as possible, to detect the fish and show the detail on the bottom. However, if the sensitivity is too high, the unit will begin to see bubbles in the water, debris, and other “background noise.”...
  • Page 46 background noise changes, the FishFinder will not adjust for this. If you choose Manual sensitivity, press the arrow on the Page control pad to go to the next line. Use the < and > arrows on the Page control pad to move the dark bar on the display.
  • Page 47 A faster chart speed setting shows more detail on the bottom. You will probably want to use a faster setting when you are looking for fish. A slower chart speed setting shows a longer record of the bottom you pass over. Any fish detected will stay on the display longer. From the display for the sensitivity setting, press the arrow on the Page control pad.
  • Page 48 Zoom Settings The “Zoom” feature allows you to enlarge or magnify a section of the normal display. This lets you see a “window” of the echo sounder view in detail. The Zoom window may be set for four different levels of magnifica- tion.
  • Page 49 display, and you are looking at the Zoom display itself. You can manually move the Zoom area up or down by pressing arrows on the Page control page. The location of the zoom area is shown by the dark vertical line at the very right-hand edge of the display.

If you are using one of the dual frequency choices, some of the fish may be revealed by one beam, but not the other.
  • Page 51 System Setup Display To change one of the items, use the arrows on 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 <...

  • Page 53 feature off, press the < control until the display indicates zero feet, fathoms or meters. When the deep alarm is set, the letter “D” will appear in the lower left-hand corner of the normal displays. If you move into deep water and trigger the alarm, the letter “D” will begin to flash, and the buzzer will sound.
  • Page 54 Once you do this, if a shallow alarm or deep alarm occurs, the “S” or “D” symbol will flash, but the buzzer will not sound. You can enable the buzzer again at any time by calling up the System Setup display, going to the line for Buzzer, and turning the item on again.
  • Page 55 Sidelooker feature. While the unit is displaying the Sidelooker page, press button once. The setup menu for the Sidelooker range will SETUP appear. Sidelooker Range Settings Once the Sidelooker feature is turned on, the FishFinder uses two range settings: one for the standard displays, and a second for just the Sidelooker feature.
  • Page 56 If you press the arrow on the Page control pad, the unit will move to the remaining menu items – zoom, frequency, and log reset. The zoom and frequency settings are for the normal displays – they will not change the Sidelooker feature.
  • Page 57 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. Always keep the display unit clean.
  • Page 58 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”).
  • Page 59 transducer and cable should be replaced as a unit. Contact Apelco for instructions. The display unit does not see the bottom or fish – Be sure the display unit is not using the Simulation mode. (If this is the case, the word “Simulation” will flash on the display.) On a unit with the transom-mount transducer, the transducer may have “kicked up”...
  • Page 60 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.
