ColorLine helps you distinguish between strong and weak sonar re-
turns. A soft, muddy or weedy bottom returns a weaker signal dis-
played as a narrow, colored line (dark blue tinged with red or a little

signal which causes a wider brightly colored line (reddish yellow to
bright yellow.) Fish are shown mostly as blue arches.
