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 TM Menu: Bottom View for
details on how to set the bottom view.
