Sonar Page

The Sonar Page is where your GPSMAP 3006C/3010C becomes a powerful

shnder/asher. If a GSD 20, GSD 21, or GSD 22 Sounder Module is not

attached, the Sonar Page appears only when the GPSMAP 3006C/3010C is in

Simulator Mode or if the Sonar check box is selected on the System tab.

To view the Sonar Page:

PressPAGErepeatedlyuntiltheSonarPageappears.

The sonar function window contains a right-to-left moving sonar image of the

water beneath your boat. Items appear as they pass under the transducer. The most

recent data is shown on the right side of the screen. The right side of the screen

contains a scale reecting the depth of the area being shown. The top-left corner

shows the depth, water temperature, and speed through water (if equipped with a

temperature or speed sensor).

Use the Fish Symbols option to view the actual sonar data, sh symbols, or a

combination of both. Fish symbols appear as red.

You can set the sonar display to show a split screen view of a zoomed portion

of the sonar, split frequencies, bottom lock (display scaled from the bottom up),

or a combination of these options. For example, you can choose to show dual

frequency at a 2X zoom (Dual 2X) on one half and normal range dual frequency

(Dual) returns on the other half. The display mode appears at the bottom of each

sonar display.
