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.
The sonar returns from the bottom, structure and fish can be represented as
either Inverse (default), WhiteLine®, Structure ID®, or Bottom Black. See
Sonar X-Press™ Menu: Bottom View for details on how to set the bottom
view.
