You, however, might consider experimenting with chart speed when you are stationary or drifting very slowly. You sometimes may achieve better images if you slow the chart speed to match how fast you are moving across the water.
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.
Sonar Page menu with Chart Speed command selected (left).
The Chart Speed Control Bar (right).
If you 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 SPEEDENT.
2.The Chart Speed Control Bar appears. Press ↓ to decrease chart speed or ↑ to increase chart speed.
3.When it's set at the desired level, press EXIT.
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 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 little 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 displayed as a wide, brightly colored line (reddish yellow to bright yellow.)
