How to Install a Fish Finder

Besides the fishing rod and tackle, the fish finder is probably the most essential piece in any fisherman's arsenal. The fish finder is essentially a sonar that uses sound waves to bounce off fish and also to find depth and obstructions on the bottom of the lake or sea. Depending on the model, the fish finder can show the size of fish, the depth that it is at, as well as the actual depth to the floor. In order for a fish finder to work properly, it needs to get installed correctly. Follow these steps to ensure a great set-up.

1. First: Determine the optimal place for the transducer

   The transducer is either mounted through suction or is attached to the boat. The recommended place to mount the transducer is on the hull, in a space free of ribs and at least a foot from the prop. Make sure that the transducer does not get touched when loading or unloading the boat from a trailer.

2. Second: Mount the transducer

   Use the mounting bracket that most likely came with the transducer, and mark using a pen or marker the area in which the screws to mount the transducer to the boat are. In addition, mark the area in which a hole needs to get drilled for wiring. Make sure everything is level, and use a small drill bit to make a starter hole before drilling the larger hole. Run the wire through the hole, and seal the hole with silicone caulk. Finish by attaching the transducer to the hull with the mounting bracket.

3. Third: Install the fish finder

   Mount the main fish finder unit on a sturdy and accessible spot. Drill starter holes followed by larger holes to mount the bracket. Attach the bracket with the screwdriver, and then attach the finder to the mounting bracket.

4. Fourth: Wire the fish finder

   Connect the electrical wire from the fish finder to either the battery or fuse box. Instructions on wiring are provided with the fish finder unit.

5. Fifth: Connect the fish finder to the transducer, and test

   Connect the wire that you ran from the transducer up to the inside of the boat, and connect with the fish finder, making sure that the wire is out of the way. Once connected, turn on the fish finder. If in the water, determine if the signal is working by moving around the water to see if the depth is changing and is able to recognize signal.
