Description:

Sonar Technology
Sonar is a technology based on sound propagation to locate and define structure, bottom contour and composition by using the transducer.
To determinate the distance of an object, the time interval between transmission of a sound wave signal by the transducer and reception of the object is measured. Then the fish finder uses the received signal to interpret the location, size and composition of the detected object.
