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 maxi-
mum when you resume trolling or moving across the water at higher
speed. To change chart speed:

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 lit-
tle 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
