Fisherman’s Guide to Fish Finders

A fish finder consists of a main unit with a screen, and a transducer. The transducer must be mounted correctly on the bottom of the boat to effectively detect reflected waves. Improperly mounted transducers may fail to detect fish or show other defects. For this reason, it is essential to carefully inspect the transducer before purchase. Some fish finders even allow for manual calibration, allowing the user to adjust the unit’s settings accordingly. hummingbird ice fish finders
