It uses sound and navigation ranging (sonar) in water depths up to one hundred meters to locate the fish and relay the information back to the screen that is usually in the hands of the person using it. Sonar works by sending out a sound wave and measuring the time it takes for the sound to return. The sound wave always projects back when it hits an object either the bottom, a fish, weeds or any other. The sound waves vary in frequency, the higher the rate, the more detailed the results will be. From this information, one can calculate the depth or height. They are also known as fish finders.
