Eagle Electronics 242 manual Grayline control bar

ample, a soft, muddy or weedy bottom returns a weaker signal which is shown with a narrow line or no gray line at all. A hard bottom returns a strong signal which will be displayed as a wide gray line.

Grayline control bar.

If you have two signals of equal size, one with gray and the other with- out, then the target with gray is the stronger signal. This helps distin- guish weeds from trees on the bottom, or fish from structure.

Grayline is adjustable. Since Grayline shows the difference between strong and weak signals, adjusting the sensitivity may also require a different Grayline level. The level chosen by the sonar unit at power on is usually adequate for most conditions. Experiment with your unit to find the Grayline setting that's best for you.

To change the Grayline level, press MENU until the GRAYLINE control bar ap- pears.
