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.

the starting depth is 5 m, the device displays a magnified area
from 5 to 20 m deep.
You also can allow the device to adjust the zoom automatically
by specifying a span. The device calculates the zoom area from
the bottom of the water. For example, if you select a span of
10 m, the device displays a magnified area from the bottom of
the water to 10 m above the bottom.

Troubleshooting
My device does not turn on
• Push the power cable all the way into the back of the device.
Even if the cable seems to be connected, you should push
firmly so that it is fully seated.
• Make sure the power source is generating power.
You can check this several ways. For example, you can
check whether other devices powered by the source are
functioning.
• Check the fuse in the power cable.
The fuse should be located in a holder that is part of the red
wire of the power cable. Check that the proper size fuse is
installed. Refer to the label on the cable or the installation
instructions for the exact fuse size needed. Check the fuse to
make sure there is still a connection inside of the fuse. You
can test the fuse using a multimeter. If the fuse is good, the
multimeter reads 0 ohm.
• Check to make sure the device is receiving at least 10 Vdc,
but 12 Vdc is recommended.
