Grayline®

Grayline lets you distinguish between strong and weak echoes. It al- lows you to tell the difference between a hard and soft bottom. For ex- 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 surface returns a strong signal, which will be displayed as a wide gray line.
