Your transducer sends a sonar signal outward through the water. When the signal hits a fish or an object, the signal bounces back to the transducer . Your transducer works with your chartplotter to interpret the signal and display an image.

If the transducer is not parallel to the water's surface, the transducer signal or beam can bounce away from the transducer . Without a consistent signal, the transducer and chartplotter cannot provide you with clear and correct images.

If your transducer is not yielding satisfactory results, you should check your installation instructions for more information about aiming the transducer beam and troubleshooting transducer placement. Even a slight adjustment to the beam angle can strengthen the signal to provide better images.
