A fish finder is an instrument used to locate fish underwater by detecting reflected pulses of sound energy. Today’s standards use a graphical display to locate schools of fish, temperature, debris and the bottom of a body of water, which can be integrated between a marine radar, compass and navigation systems. They are used in rivers, lakes and the ocean by anglers and commercial fisherman alike. You can get them with a high-resolution display or GPS and the list goes on, but its main function is to be a tool in finding fish. Anglers, however, can still misinterpret what a fish-finder is used for and how versatile it can be.
