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.

Side Beam View
(QuadraBeam
TM
Only)
Side Beam View shows sonar information from both the left and right 90° 455 kHz beams
and the 200 kHz down-looking beam in one view. The top portion of the display presents a
historical log of sonar returns from the 200 kHz down-looking sonar. The bottom portion of
the display presents a historical log of sonar returns from the 455 kHz right- and left-looking
sonar. New information appears at the top, and scrolls down the display in the 455kHz
Windows. The sonar information from the side-looking beams reveal bottom contour,
structure and fish similar to the down-looking beam, but the area covered is to the left and
right of the area shown in the down-looking portion so you actually see more of the bottom.
The distance covered by the right and left 90° beams is based on the depth setting for the
down-looking beam, up to a maximum of 160 feet.
The digital readouts in the Side Beam View cannot be customized.
