through the sonar signal cone, the image appears on the screen as a
long line instead of a fish arch. Reducing the chart speed may result in
a shorter line that more closely resembles a regular fish return.

If you do experiment with chart speed, remember to reset it to maxi-
mum when you resume trolling or moving across the water at higher

ColorLine
ColorLine lets you distinguish between strong and weak echoes. It
paints a brighter color on targets that are stronger than a preset value.
This allows you to tell the difference between a hard and soft bottom.
For example, a soft, muddy or weedy bottom returns a weaker signal
which is shown with a narrow, colored line (dark blue tinged with red
or a little yellow.) Since fish are among the weakest echoes, they show
up mostly as blue arches. A hard bottom or other relatively hard target
returns a strong signal which causes a wider brightly colored line (red-
dish yellow to bright yellow.)
If you have two signals of equal size, one with red to yellow color and
the other without, then the target with brighter color (yellow) is the
stronger signal. This helps distinguish weeds from trees on the bottom,
or fish from structure. ColorLine is adjustable. Experiment with your
unit to find the ColorLine setting that's best for you.
