Why is my Furuno FCV-587 Fish Finder sensitivity so low?
Low sensitivity on your Furuno Fish Finder can be caused by several factors. Check the gain setting. Ensure that air bubbles or marine life are not clinging to the transducer face, and that sediments are not present in the water. Also, the bottom may be too soft to return an echo.
