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.
