1 1 – Intr oduction About the FishFinder L365 The FishFinder L365 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 displa y unit, connected by a cabl e. The tr ansducer sends high-frequency sound wa ves do wn into the water . These sounds strike fish, the b[...]

2 Introduction System Components The FishFinder L365 consists of a compact display unit connected to a transducer . The tr ansducer is attached to the boat and extends into the wa te r. Standard Equipment When you unpack your FishFinder L365, you should find the following standard equipment in the carton. If any items are missing, please notify y o[...]

9 • The brac ket has a quic k-release mechanism. This ma y reduce damage by allowing the transducer to flip up if it hits any debris or the bottom. See Fig. 2-4. Allow enough clear ance abov e the transducer so that it can swing upw ard completely . This is about 10" (254 mm) measured from the bottom of the transom. • If considering the Si[...]

10 Installation 6. Attach the brac ket to the hull using the panhead scre ws 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 penetr a- tion. Do not tighten the screws completely yet. 7. Move the bracket up or down so that the leading edge of the trans- d[...]

11 Installation 5. Run the Sidelook er cable beside the depth cable f or the transom- mount transducer . Installation Notes – Thr u-Hull T r ansducer Detailed instructions for this installation will be included with the trans- ducer . In this section, we will note just a few important points. 1. Earlier we listed three general rules for placing t[...]

12 f ai ring block must be ab le to resist the drag of the water against the hull, and must also be completely waterproof. 6. If the hull of the boat has a core-type hull, you will need to follow some special mounting procedures. The core mater ial must be protected from any water which may leak from the inside of the boat. (If the core material is[...]

During the installation, do not cut the transducer cab le or[...]

19 keep the tr ansducer cable aw ay from the antenna and po wer 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. 3. Be careful not to tear the cable jacket when passing it through bul[...]

20 Installing the T ransducer Cab le – Installation with Separate Speed and T emperature Sensors 1. Optional depth - only and speed - and temperature - only transducers are av ailable for the FishFinder L365. In this optional configuration the separate tr ansducers are connected via a “ Y ” type receptacle cable located on the optional speed-[...]

21 2. The 5-foot po wer cable (1.5 m) supplied with the displa y unit should reach the source of DC pow er. On a small boat, connect the power leads directly to the main battery isolation switch or breake r. On a larger boat, route the power leads to the DC power distribution panel. 3. It is ve r y impor tant that you connect the power leads correc[...]

22 in spite of the longer wire distance. F or runs of 20 to 35 feet (6 to 10.6 m), use #14 A WG. If you e xtend the power wiring, be sure all electrical connections are solid and durable. Soldering is the best way to make these connec- tions. Insulate all connections using heat-shrink tubing or electrical tape. Y ou ma y also use cr imp connectors [...]

23 3. If the display unit is reading high or low , you can correct f or this using the entry for “ Speed Cal. ” (T o reach Speed Cal, go to the System Setup display . This is descr ibed in Section 4.) The entr y for Speed Cal is a percentage. An entry of “ 100 ” equals 100%, meaning that there is no correction. If the display unit is produc[...]

24 3 – Operating Instr uctions In this section of the manual, w e will explain how to operate the unit. (Setup instructions are included in the next section.) Below is a drawing of the display unit.

26 This unit has a memory for some of the settings – range, sensitivity , zoom, and frequency . (W e will explain these in a moment.) When you tur n off the powe r , any changes y ou make to these settings will be sa ved. Y ou can return all of the settings to the factory default values, and reset the trip log to zero . T o reset the unit, tur n [...]

28 Adjust contrast Y ou can also adjust the “ contr ast ” of the displa y . This is a measure of how light or dark the display appears. Use the V control to mov e from the line f or “ Lamp On/Off ” to the line fo r “ Contrast. ” Use the < or > controls to adjust the contrast. (The FishFinder unit has a feature which adjusts the co[...]

29 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 “ char t ” or “ bottom graph ” display .) As time passes, this displa y scrolls from right to left.[...]

30 Some of these echoes indicate fish, and others show the bottom. As ne w echoes are receiv ed, the FishFinder “dra ws” a g raph of the bottom. The bottom g raph helps you to tell whether the bottom is rising or falling. It also allo ws you to identify the shape or “structure” of the bottom. This can indicate a reef or shipwreck. Notice th[...]

31 Auto z oom 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 displa y , 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 s[...]

32 W ater 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 par ticular 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[...]

33 Buzzer symbol This symbol shows whether any of the alarms will use the buzze r . 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 Buzz er symbol shows whether the alarms will also use the buzzer . If the Buzzer setting in the System Setup displ[...]

34 Before w e explain the other pages, there are some general things y ou should know about the operation of the FishFinder . Choosing a F requency W e said that the FishFinder uses sound wa ves to “ see ” through the water under the boat. The “ frequency ” is a measure of how f ast the sound w aves change or “ vibrate. ” The FishFinder[...]

35 Fish Indications Even using adv anced 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 wa ves to bounce off of. The FishFinder L365 is very good at telling the difference between a fish and the surro[...]

36 Operating Instructions A shallow arch or horizontal line is generated when the boat is moving slowly or stopped. An arch-shaped image indicates a fish. This indicates a group of small fish. This shows a fish detected in sidelooker mode. When the boat is moving very fast, a fish appears as a single vertical line. The same fish appears differently[...]

37 Hard (Sand) Rocks Soft (Mud) Fig. 3-6 Bottom Conditions Operating Instructions Notice that the low er layer of the bottom is sho wn 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 lay er, and ma y be reflected by a more solid la yer[...]
