You can also use a mild soap and water solution if necessary.

Be sure to avoid using any harsh chemicals or abrasives, as these can damage the screen.

3.  Check the Transducer

The transducer is part of the fish finder that emits and receives the sonar waves that are used to locate fish.

You should check the transducer regularly to make sure that it is clean and free of debris.
