Unnecessary echoes

Sea surface reflections

To reduce sea surface reflections, set the tilt angle to 4° or higher, so the upper edge
of the sonar beam does not hit the sea surface, or adjust near gain. When a decreased
tilt is used, sea surface reflections cover a large area as illustrated below.

Wake

A wake produced by own ship or another ship can be a strong reflecting object when
a decreased tilt angle is used. As the wake appears as a thick continuous line, it can
be easily distinguished from a school of fish. A wake contains many air bubbles which
attenuate ultrasonic energy, making it difficult to sound beyond the wake.
