Inverse is a method where weak returns are shown with
dark pixels and strong returns with lighter pixels. This has
the benefit of ensuring that weak signals will be clearly
visible on the display.
Structure ID® represents weak returns as light pixels and
strong returns as dark pixels. This has the benefit of
ensuring that strong returns will be clearly visible on the
display.
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.
Black (Bottom Black) displays all pixels below the bottom
contour as black, regardless of signal strength. This has
the benefit of providing a high contrast between the
bottom and other sonar returns on the display.
