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 there
for most all fishing conditions. You, however, might consider experi-
menting with chart speed when you are stationary or drifting very
slowly. You may sometimes achieve better images as you slow down 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 experiment with chart speed, remember to reset it to maximum
when you resume trolling or moving across the water at higher speed.
