Fish Finder User's Manual

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.
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.
NOTE: Bottom Black View is not available on color
models.
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.
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.
NOTE: Inverse View is not available on color models.
