6 Use a trolling motor transducer if –. . . you want to attach the transducer to a trolling motor. (Not recom-mended for deep-water operations.) Use a Sidelooker transducer if –. . . you need a way of searching for fish on either side of the boat. Thistype of transducer is attached to the bracket of...

9 • The bracket has a quick-release mechanism. This may reducedamage by allowing the transducer to flip up if it hits any debris or thebottom. See Fig. 2-4. Allow enough clearance above the transducerso that it can swing upward completely. This is about 10" (254 mm)measured from the bottom of th...

10 Installation 6. Attach the bracket to the hull using the panhead screws with flatwashers. Before you tighten the screws, apply a good-quality marinesealant to the pilot holes. This will protect the hull from water penetra-tion. Do not tighten the screws completely yet. 7. Move the bracket up or d...

11 Installation 5. Run the Sidelooker cable beside the depth cable for the transom-mount transducer. Installation Notes – Thru-Hull Transducer Detailed instructions for this installation will be included with the trans-ducer. In this section, we will note just a few impor tant points. 1. Earlier we ...

21 2. The 5-foot power cable (1.5 m) supplied with the display unit shouldreach the source of DC power. On a small boat, connect the powerleads directly to the main battery isolation switch or breaker. On alarger boat, route the power leads to the DC power distribution panel. 3. It is very impor tan...

22 in spite of the longer wire distance. For runs of 20 to 35 feet (6 to10.6 m), use #14 AWG.If you extend the power wiring, be sure all electrical connections aresolid and durable. Soldering is the best way to make these connec-tions. Insulate all connections using heat-shrink tubing or electricalt...

23 3. If the display unit is reading high or low, you can correct for this usingthe entry for “Speed Cal.” (To reach Speed Cal, go to the SystemSetup display. This is described in Section 4.) The entry for SpeedCal is a percentage. An entry of “100” equals 100%, meaning thatthere is no correction. I...

35 Fish Indications Even using advanced sonar technology, it is sometimes hard to detect afish in the water. The body of a fish is just a little more dense than thesurrounding water. There is really nothing very solid for the sound wavesto bounce off of. The FishFinder L365 is very good at telling t...

36 Operating Instructions A shallow arch or horizontal line isgenerated when the boat is movingslowly or stopped. An arch-shaped image indicates a fish. This indicates a group of small fish.
