The fish finder was then modified from fathometer to obtain the reading from the reflection of sound signals below. The shape, size, and composition of any object such as a fish are reflected on the computer screen.

A transducer or what some may call hydrophone is used to send sound signal below the sea water – since the speed at which this sound travels down through water (sea water or fresh water) is known, the distance to the reflected object can be determined. With this, you can easily determine the location and the distance to the fish.
