It uses sonar to locate and define structure, bottom contour and composition, and depth directly below the transducer. The transducer sends a sound wave signal and determine distance by measuring the time between the transmission of the sound wave. When the sound wave is reflected off an object, it then uses the reflected signal to interpret location, size and composition of an object  How to use Wireless Sonar Sensor Just simply attach the transducer to the end of your fishing line and case it into the water as you would normally float or lure.Attention 1.The product can show you how big the fish are, and the Sensitivity settings adjustable.
