Chart Speed
The rate echoes scroll across the screen is called chart speed. The de-
fault is maximum. We recommend you keep the default setting for most
all fishing conditions.
You may consider experimenting with chart speed when you are sta-
tionary or drifting slowly. Sometimes the unit will display better im-
ages when chart speed is adjusted to match the speed of your boat.
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.

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.
