Sometimes, you may achieve better images as you decrease the chart speed to match the speed of your boat.
If you are at anchor, ice fishing or fishing from a dock, experiment with a chart speed of 25 percent. If you are drifting slowly, try a chart speed of 50 percent. When you are stationary and a fish swims through the sonar signal cone, the image appears on the screen as a long line in- stead of a fish arch. Reducing the chart speed may result in a shorter line that more closely resembles a regular fish return.
To adjust Chart Speed, repeatedly press MENU until the CHART SPEED scroll bar appears. Press ↑ to increase the speed of the chart. Press ↓ to decrease it. Press PWR to clear the menu.
To return to the original setting, repeat the steps above, but use the arrow keys to set the speed to 100% before clearing the menu.
