fishfinder

Underwater detection device

A fishfinder is an electronic device that uses sonar to locate fish underwater.

Mounted on boats, it displays depth, bottom contours, and fish as distinct marks on a screen: The fishfinder showed a school of bass hovering near the drop-off.

Modern units combine GPS, mapping, and fish-locating functions.
