NOTE: To receive Garmin ClearVü scanning sonar, you need a
compatible transducer.
Garmin ClearVü high-frequency sonar provides a detailed
picture of the fishing environment around the boat in a detailed
representation of structures the boat is passing over.

Bottom echo
Traditional transducers emit a conical beam. The Garmin
ClearVü scanning sonar technology emits two narrow beams,
similar to the shape of the beam in a copying machine. These
beams provide a clearer, picture-like image of what is around
the boat.
Split-Screen Frequency
You can view two frequencies from the split frequency screen.
Shift-Zoom View
On the sonar screen, you can see a full-view graph of sonar
readings on the right side of the screen, and a magnified portion
of that graph on the left side of the screen.
Shift allows you to set the depth range on which the sonar is
focused. This allows you to zoom in a higher resolution in the
focused depth.
When using shift, bottom tracking may not work effectively,
because the sonar looks for data within the depth range of the
focused area, which may not include the bottom. Using shift also
can impact the scroll speed, because data outside the depth
range of the focused area is not processed, which reduces the
time required to receive and display the data. You can zoom in
to the focused area, which enables you to evaluate target
returns more closely at a higher resolution than just zooming
alone.
The shift-zoom view is not available on all sonar screens.
From a sonar screen, select
ZOOM > Shift Zoom .
