The FishFinder 365 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 365 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
•
measure the speed of the boat and the distance traveled
•
show the water temperature
We are sure you will find the FishFinder 365 to be one of the most useful
devices on your boat.

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 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. This is helpful when you are looking for fish near river banks, or under docks or piers. The Sidelooker transducer is attached to the same mounting bracket used with the transom-mount transducer.
- Page 11 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(s) and shaft(s).
- Page 12 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. 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.
- Page 13 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.

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 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. 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.
- Page 17 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.
- Page 18 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.
- Page 19 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 365. This is shown below in Fig. 2-14. Sensor for...
- Page 20 use on boats with positive ground. The 6-foot power cable supplied with the display unit should reach the source of DC power. On a small boat, connect the power leads directly to the main battery isolation switch or breaker. On a larger boat, route the power leads to the DC power distribution panel.
- Page 21 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. If you extend the power wiring, be sure all electrical connections are solid and durable.
- Page 22 over ground” or “speed over the bottom.” Tides, currents, or winds can create a difference between the FishFinder’s “speed through water” measurement and the boat’s “speed over ground.” Before calibrating using a G.P.S. or Loran unit, wait for still water or slack tide conditions.

- Page 29 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 30 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 31 Water temperature This entry shows the current water temperature at the surface of the water. (The reading for water temperature can be helpful for finding fish. A particular type of fish will often prefer water in a narrow temperature range.) From the System Setup display, you can turn this item off or change the units used for this display.
- Page 32 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.
- Page 33 Before we explain the other pages, there are some general things you should know about the operation of the FishFinder. 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.”...
- Page 34 There is really nothing very solid for the sound waves to bounce off of. The FishFinder 365 is very good at telling the difference between a fish and the surrounding water. In fact, Apelco is the leader in this technology.
- Page 35 An arch-shaped image indicates a fish. The same fish appears differently when shown by the 50 kHz or 200 kHz 50 kHz transducer beams. 200 kHz This indicates a group of small fish. This shows a fish detected in sidelooker mode. A shallow arch or horizontal line is generated when the boat is moving slowly or stopped.
- Page 36 Hard (Sand) Soft Rocks (Mud) Bottom Conditions 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.
- Page 37 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 38 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 39 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 40 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 41 This is the speed of the boat through the water. This entry shows the distance traveled, determined by the speed through the water. The 365 remembers this value after it is turned off. You may reset the log using the Setup Menu.
- Page 42 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.

This means that you can reach these displays quickly, make a change, then return to the normal display quickly.
- Page 46 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 of the Page control pad to select Auto or Manual range.
- Page 47 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 48 background noise changes, the FishFinder will not adjust for this. If you choose Manual sensitivity, press the arrow of the Page control pad to go to the next line. Use the < and > arrows of the Page control pad to move the dark bar on the display.
- Page 49 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 of the Page control pad.
- Page 50 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 echosounder view in detail. The Zoom window may be set for four different levels of magnifica- tion.

- Page 56 When the shallow alarm is set, the letter “S” will appear in the lower left-hand corner of the normal displays. If you move into shallow water and trigger the alarm, the letter “S” will begin to flash, and the buzzer will sound. Press the button to silence the buzzer.
- Page 57 silence the buzzer for the current alarm condition . The “S” or “D” symbol will continue to flash as long as the alarm condition is still present. If the alarm condition occurs again, the buzzer will sound again. (For example, this would happen if, after a shallow alarm you move into deep water, then return to shallow water.) You can silence the buzzer again by pressing the button.
- Page 58 You can choose Fahrenheit degrees (°F) or Celsius degrees (°C). Use the < and > controls to make your choice. Speed A speed indication appears on all of the normal displays. If you do not want to see this item, you can turn it off using this line of the System Setup display.

- Page 62 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 63 the factory defaults. See the default settings on page 61. 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.
- Page 64 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 Apelco for instructions.
- Page 65 the System Setup display. The FishFinder will not display arches unless the boat is moving. If the boat is stopped, fish will appear on the display as straight lines. The transducer may not be aimed straight down. In order to display complete arches, the transducer must be vertical.
