The Whiteline setting controls how the unit displays information about the bottom type (hard or soft). With Whiteline off, the bottom return displays as a solid color. With Whiteline on, the strongest area of bottom return becomes white and can be used to determine bottom hardness. A hard bottom returns a stronger signal and displays a thicker bottom layer. A soft bottom returns a weaker signal and displays a thinner bottom layer.
