A fish finder sends sound waves through water. At the source, these sound waves are narrow and gradually widen to form a cone. This is whats referred to as a beam. When the beam encounters something different (a solid object like a fish or a lake bottom), it bounces back to the fish finders transducer which convert those minute echoes into an image you can interpret on the display. Some of the more advanced fish finders will have more than one beam so youll get a clearer image of whats happening below the surface of the water as well as a general direction of where the fish are (left, right, front, back). A wider cone will give you a wider coverage area and is therefore preferable over a narrow cone for shallower waters.

Fish finders use Sonar to locate objects, preferably fish, underwater. Sonar is an abbreviation for SOund, NAvigation, and Ranging. Sonar consists of 4 parts: the transmitter, transducer, receiver and display. Basically Sonar works by sending an electrical impulse from the transmitter, converting it into a sound wave by the transducer and then sending that sound wave into the water. When the wave strikes an object it rebounds off the object sending this echo back to the transducer. The transducer than converts the echo back into an electrical signal. The receiver amplifies this signal and sends it to the display for the fisherman to see. Now the fisherman knows where to drop a line.
