Structure ID represents weak returns in blue and strong returns in red (original palette). If
the Palette is changed, the Structure ID will display the strongest return as specified by the
palette.
WhiteLine highlights the strongest sonar returns in white. This has the benefit of clearly
defining the bottom on the display.
Select Bottom Fill to see the shaded bottom filled in with a solid color on the view. This has
the benefit of clearly defining the bottom location on the display.
Select Bottom Line to display the depth reading from the Depth Source as a line, either from
the selected transducer or another digital depth source. See Set up your Humminbird
Network for details about selecting sources.
