How Sonar Works
Sonar innovation is based on sound waves. It utilizes finder to find and define structure, bottom shape and structure, and depth directly listed below the transducer. The transducer sends a sound wave signal and figure out distance by measuring the time between the transmission of the sound wave. When the sound wave is reflected off an item, it then utilizes the shown signal to translate location, size and structure of an object.

Ways to utilize Wireless Sonar Sensor
Just just connect the transducer to the end of your fishing line and case it into the water as you would usually drift or lure.
