Viewing two frequencies concurrently using the split-frequency
view allows you to see deeper with the lower frequency return
and, at the same time, see more detail from the higher
frequency return.
Selecting Frequencies
NOTE: You cannot adjust the frequency for all sonar views and
transducers.
You can indicate which frequencies appear on the sonar screen.

Adjusting the Zoom
You can adjust the zoom manually by specifying the span and a
fixed starting depth. For example, when the depth is 15 m and
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 an magnified area from the bottom of
the water to 10 m above the bottom.

Locking the Screen to the Water Bottom
You can lock the screen to the water bottom. For example, if you
select a span of 20 meters, the device shows an area from the
water bottom to 20 meters above the bottom. The span appears
on the right side.

Sonar Gain
The gain setting controls the sensitivity of the sonar receiver to
compensate for water depth and water clarity. Increasing the
gain shows more detail, and decreasing the gain reduces screen
clutter.
NOTE: Setting the gain on one sonar view applies the setting to
all the views.

Adjusting the Range of the Depth Scale
You can adjust the range of the depth scale that appears on the
right side of the screen. Automatic ranging keeps the bottom
within the lower third of the sonar screen, and can be useful for
tracking the bottom where there are slow or moderate terrain
changes.
When the depth changes dramatically, like a drop off or cliff,
manually adjusting the range allows a view of a specified depth
range. The bottom is shown on the screen as long as the bottom
is anywhere within the manual range established.

You can set the rate at which the sonar image moves across the

information on the screen longer. Setting the scroll speed on
