automatically, select Auto Low.
Hiding Surface Noise
You can hide or display the sonar returns near the surface of the
water. Hiding surface noise helps reduce screen clutter.
NOTE: Setting the surface noise to show or hide on one screen
applies that setting to all screens.
This feature may not be available with all transducers.
From a sonar screen, select
Reject > Surface Noise.
Interference
The Interference setting adjusts sonar sensitivity to reduce the
effects of interference from nearby sources of noise.
When you adjust the interference setting from off
, medium
, and high
there is little effect on the strong target returns.
Use the lowest interference setting that achieves the desired
improvement to remove interference from the screen. Correcting
installation issues that cause noise is the best way to eliminate
interference.

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.

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.

Setting the Bottom Search Limit
You can set a maximum depth at which the auto range feature
searches for the bottom. A lower limit acquires data about the
bottom faster than a higher limit.

Sonar Frequencies
NOTE: The frequencies that are available depend on the
transducer being used.
Adjusting the frequency helps adapt the sonar for your particular
goals and the present depth of the water.
Selecting Frequencies
NOTE: You cannot adjust the frequency for all sonar views and
transducers.
You can indicate which frequencies appear on the sonar screen.

Setting the Scroll Speed
You can set the rate at which the sonar image moves across the
screen. A higher scroll speed shows more detail, especially
while moving or trolling. A lower scroll speed displays sonar
information on the screen longer. Setting the scroll speed on
one sonar view applies to all the sonar views.
