Chart Speed
The rate that echoes scroll across the screen is called the chart speed.
The default is maximum. We recommend you leave the speed set at de-
fault for virtually all fishing conditions.
However, you might consider experimenting with chart speed when you
are stationary or drifting very slowly. You may sometimes achieve bet-
ter images as you slow down the chart speed to match how fast you are
moving.
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 experiment with chart speed remember to reset it to maximum
when you resume trolling or moving across the water at higher speeds.
