Use Bottom View to select the method used to represent bottom and structure on the display. See Sonar Menu Tab to set the Bottom View.

Structure ID® represents weak returns in blue and strong returns in red when Sonar Colors is set to Original. If the Sonar Colors palette is changed, the Structure ID® will display the strongest return as specified by the palette. See Sonar Menu Tab: Sonar Colors for more information.

WhiteLine™ highlights the strongest sonar returns in white, resulting in a distinctive outline. This has the benefit of clearly defining the bottom on the display.
