How does the sonar sensor work?
Sonar technology is based on sound waves. The system uses sonar to locate and define structure, composition, as well depth directly below the transducer of up to 45 degrees coverage. The transducer sends a sound wave signal and determines the distance by measuring the time between the transmission of the sound wave and when the sound wave is reflected off an object. It then uses the reflected signal to interpret the location, size, and composition of an object. This portable fishfinder is brought to you buy Intermart.
