How Sonar Works: Sonar technology is based on sound waves. The Tracer uses sonar to locate and define structure, bottom contour and composition, as well depth directly below the transducer. The transducer sends a sound wave signal and determines distance by measuring the time between the transmission of the sound wave and when the sound wave is reflected off an object and it uses the reflected signal to interpret location, size, and composition of an object.
