Chart Speed
The rate that echoes scroll across the screen is called the chart scroll
speed. The default for this unit is the maximum, 100 percent.
Chart Speed control bar.
NOTE:
When you are stationary or traveling slowly and using a higher
chart speed, a fish swimming through the sonar signal will be dis-
played as a long line instead of a fish arch. You can counteract this
by decreasing the chart speed to match the speed of your boat,
which will shorten the line, making it look more like a fish arch.
To adjust Chart Speed:
1. Press MENU until the CHART SPEED control bar appears. Press to in-
crease the speed of the chart. Press to decrease it.
2. Press
PWR to clear the menu.
Fish I.D.
The Fish I.D. feature displays fish symbols on the screen in place of the
actual fish echoes. There are three symbol sizes: small, medium and
large. These show the relative size between targets.
