Sonar Bottom Presentation
As the boat moves, the unit charts the changes in depth on the display to create a profile of the
Bottom Contour. The type of bottom can be determined from the return charted on the display.
A Hard Bottom such as compacted sediment or flat rock appears as a thinner line across the
display. A Soft Bottom such as mud or sand appears as a thicker line across the display. Rocky
Bottoms have a broken, random appearance.
