GRAYLINE®

GRAYLINE® lets you distin- guish between strong and weak echoes. It “paints” gray on targets that are stronger than a preset value. This al- lows you to tell the difference between a hard and soft bot- tom. For example, a soft, muddy or weedy bottom re- turns a weaker signal which is

shown with a narrow or no gray line. A hard bottom returns a strong signal which causes a wide gray line.

If you have two signals of equal size, one with gray and the other without, then the target with gray is the stronger signal.This helps distinguish weeds from trees on the bottom, or fish from structure.

GRAYLINE® is adjustable. Since GRAYLINE® shows the difference be- tween strong and weak signals, adjusting the sensitivity may require a

GRAYLINE® ON
