Whenever a sound wave hits some type of item, it rebounds itself; meaning, that when the sound waves echo hits the transducer, it will convert it back into an electrical signal, which is then amplified by the receiver and finally, it is sent to the display where you can see it.

On the display, you will see a history of the echoes, you are also able to customize your display, you can make it as sensitive as you want, you can change the depth range and also the chart speed.
