traditional transducers or the contrast for DownVü and SideVü/

DownVü transducers. This setting works best after you have

adjusted the level of detail shown on the screen using the gain

or brightness settings.

If you want to highlight smaller fish targets or create a higher

intensity display of a target, you can increase the color gain or

contrast setting. This causes a loss in the differentiation of the

high intensity returns at the bottom. If you want to reduce the

intensity of the return, you can reduce the color gain or contrast.

From a sonar view, select MENU.

Select an option:

• While in the DownVü or SideVü sonar view, select

Contrast.

• While in another sonar view, select Sonar Setup >

Advanced > Color Gain.

Select an option:

• To increase or decrease the color intensity manually,

select Up or Down.

• To use the default setting, select Default.

Adjusting the Range of the Depth or Width

Scale

You can adjust the range of the depth scale traditional and

DownVü sonar views and the range of the width scale for the

SideVü sonar view.

Allowing the device to adjust the range automatically keeps the

bottom within the lower or outer third of the sonar screen, and

can be useful for tracking a bottom that has minimal or

moderate terrain changes.

Manually adjusting the range enables you to view a specified

range, which can be useful for tracking a bottom that has large

terrain changes, such as a drop-offs or cliffs. The bottom can

appear on the screen as long as it appears within the range you

have set.

From a sonar view, select MENU > Range.

Select an option:

• To allow the chartplotter to adjust the range automatically,

select Auto.

• To increase or decrease the range manually, select Up or

Down.

TIP: From the sonar screen, you can select

manually adjust the range.

Setting the Zoom Level on the Sonar Screen

From a sonar view, select MENU > Zoom.

Select an option:

• To zoom in on the sonar data from the bottom depth,

select Bottom Lock.

• To set the depth range of the magnified area manually,

select Manual, select View Up or View Down to set the

depth range of the magnified area, and select Zoom In or

Zoom Out to increase or decrease the magnification of

the magnified area.

• To set the depth and zoom automatically, select Auto.

• To cancel the zoom, select No Zoom.

Sonar Frequencies

NOTE: The frequencies available depend on the chartplotter,

sounder modules, and transducer being used.

Adjusting the frequency helps adapt the sonar for your particular

goals and the present depth of the water.

Higher frequencies use narrow beam widths, and are better for

high-speed operation and rough sea conditions. Bottom

Sonar

definition and thermocline definition can be better when using a

higher frequency.

Lower frequencies use wider beam widths, which can let the

fisherman see more targets, but could also generate more

surface noise and reduce bottom signal continuity during rough

sea conditions. Wider beam widths generate larger arches for

fish target returns, making them ideal for locating fish. Wider

beam widths also perform better in deep water, because the

lower frequency has better deep water penetration

Chirp frequencies allow you to sweep each pulse through a

range of frequencies, resulting in better target separation in

deep water. Chirp can be used to distinctly identify targets, like

individual fish in a school, and for deep water applications.

Chirp generally performs better than single frequency

applications. Because some fish targets may show up better

using a fixed frequency, you should consider your goals and

water conditions when using Chirp.

Some sonar black boxes and transducers also provide the

ability to customize preset frequencies for each transducer

element, which enables you to change the frequency quickly

using the presets as the water and your goals change.

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.

From a sonar view, select MENU > Frequency.

Select a frequency suited to your needs and water depth.

For more information on frequencies, see

Frequencies.

Creating a Frequency Preset

NOTE: Not available with all transducers.

You can create a preset to save a specific sonar frequency,

which allows you to change frequencies quickly.

From a sonar view, select MENU > Frequency.

Select Add.

Enter a frequency.

Turning On the A-Scope

NOTE: This feature is not available in all sonar views.

The a-scope is a vertical flasher along the right side of the full-

screen sonar view. This feature expands the most recently

received sonar data so that it is easier to see. It can also be

helpful for detecting fish that are close to the bottom.

From a sonar view, select MENU > Sonar Setup >

Appearance > A-Scope.

Selecting the Transducer Type

Before you can select the transducer type, you must know what

kind of transducer you have.

If you are connecting a transducer that was not included with

the chartplotter, you may need to set the transducer type to

make the sonar function properly. If the device automatically

detected your transducer, this option does not appear.

From a sonar view, select MENU > Sonar Setup >

Installation > Transducer Type.

Select an option:

• If you have a 200/77 kHz, dual-beam transducer, select

Dual Beam.
