Chart Speed
The rate echoes scroll across the screen is called the chart speed. The
default is maximum. We recommend you leave the setting there for
virtually all fishing conditions.
You, however, might consider experimenting with chart speed when
you are stationary or drifting very slowly. You may sometimes achieve
better images as you slow the chart speed to match how fast you are
moving across the bottom.
If you are at anchor, ice fishing or fishing from a dock, experiment with
a chart speed around 50 percent. If you are drifting slowly, try a chart
speed around 75 percent. When you are stationary and a fish swims
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
maximum when you resume trolling or moving across the water at
higher speed. To change chart speed:
1. From the Sonar Page, press
MENU|↓ to CHART SPEED|ENT.
2. The Chart Speed Control Bar appears. Press ↓ to decrease chart
speed. Press ↑ to increase chart speed.
3. When it's set at the desired level, press

ColorLine
ColorLine lets you distinguish between strong and weak echoes. It
"paints" a brighter color on targets that return a stronger signal. This
allows you to tell the difference between a hard and soft bottom. For
