Each chartplotter on the network can display sonar data from

every compatible sonar module and transducer on the network,

no matter where the chartplotters and transducers are mounted

on your boat. For example, from one GPSMAP 8417 device

mounted at the back of the boat, you can view the sonar data

from another GPSMAP device and Garmin ClearVü transducer

mounted at the front of your boat.

When sharing sonar data, the values of some sonar settings,

such as Range and Gain, are synchronized across the devices

on the network. The values of other sonar settings, such as the

Appearance settings, are not synchronized and should be

configured on each individual device. In addition, the scroll rates

of the various traditional and Garmin ClearVü sonar views are

synchronized to make the split views more cohesive.

NOTE: Using multiple transducers simultaneously can create

cross talk, which can be removed by adjusting the Interference

sonar setting.

Adjusting the Level of Detail

You can control the level of detail and noise shown on the sonar

screen either by adjusting the gain for traditional transducers or

by adjusting the brightness for Garmin ClearVü transducers.

If you want to see the highest intensity signal returns on the

screen, you can lower the gain or brightness to remove lower

intensity returns and noise. If you want to see all return

information, you can increase the gain or brightness to see more

information on the screen. This also increases noise, and can

make it more difficult to recognize actual returns.

From a sonar view, select Menu.

Select Gain or Brightness.

Select an option:

• To increase or decrease the gain or brightness manually,

select Up or Down.

• To allow the chartplotter to adjust the gain or brightness

automatically, select an automatic option.

Adjusting the Color Intensity

You can adjust the intensity of colors and highlight areas of

interest on the sonar screen by adjusting the color gain for

traditional transducers or the contrast for Garmin ClearVü and

SideVü/ClearVü 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 Garmin ClearVü or SideVü sonar view, select

Contrast.

• While in a Panoptix LiveVü sonar view, select Color Gain.

• While in another sonar view, select Sonar Setup >

Appearance > Color Gain.

Select an option:

• To increase or decrease the color intensity manually,

select Up or Down.

• To use the default setting, select Default.

Sonar Recordings

Recording the Sonar Display

Insert a memory card into the card slot.

From a sonar view, select Menu > Sonar Setup > Sonar

Recording > Record Sonar.

15 minutes of sonar recording uses approximately 200 MB of

space of the inserted memory card. An individual recording

automatically ends after it reaches 4 GB in size. You can

record sonar data until the card reaches capacity.

Stopping the Sonar Recording

Before you can stop recording sonar, you must begin recording

it (Recording the Sonar Display, page 28).

From a sonar view, select Menu > Sonar Setup > Sonar

Recording > Stop Recording.

Deleting a Sonar Recording

Insert a memory card into the card slot.

From a sonar view, select Menu > Sonar Setup > Sonar

Recordings > View Recordings.

Select a recording.

Select Review > Delete.

Playing Sonar Recordings

Before you can play back the sonar recordings, you must

download and install the HomePort

™

application and record

sonar data onto a memory card.

Remove the memory card from the device.

Insert the memory card into a card reader attached to a

computer.

Open the HomePort application.

Select a sonar recording from your device list.

Right-click the sonar recording in the lower pane.

Select Playback.

Traditional, Garmin ClearVü, and SideVü

Sonar Setup

NOTE: Not all options and settings apply to all models, sounder

modules, and transducers.

NOTE: These settings do not apply to Panoptix transducers.

From a sonar view, select Menu > Sonar Setup.

Scroll Speed: Sets the rate at which the sonar scrolls from right

to left (Setting the Scroll Speed, page 29).

In shallow water, you can select a slower scroll speed to

extend the length of time the information is displayed on

screen. In deeper water, you can select a faster scroll speed.

Automatic scroll speed adjusts the scrolling speed to the

speed the boat is traveling.

Noise Reject: Reduces the interference and the amount of

clutter shown on the sonar screen (Sonar Noise Rejection

Settings, page 29).

Appearance: Configures the appearance of the sonar screen

(Sonar Appearance Settings, page 29).

Alarms: Sets sonar alarms (Sonar Alarms, page 30).

Advanced: Configures various sonar display and data source

settings (Advanced Sonar Settings, page 30). Not

applicable to Garmin ClearVü or SideVü sonar views.

Installation: Configures the transducer (Traditional, Garmin

ClearVü, and SideVü Transducer Installation Settings,

page 30).

Setting the Zoom Level on the Sonar Screen

From a sonar view, select Menu > Zoom > > Mode.

Select an option:

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

If necessary, select Set Zoom to modify the zoom setting.

Select View Up or View Down to set the depth range of

the magnified area, and select Zoom In or Zoom Out to
