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
WhiteLine®
or
Structure ID®
. See
Sonar Menu Tab: Bottom View
for
details on how to set the bottom view.
