Sonar 

You can set whether the sonar returns near the surface of the water appear. Hide surface noise to help reduce 

clutter.

From the Home screen, select Sonar > Sonar Setup > Surface Noise > Show.

You can set whether a quick-reference depth line appears.
1.  From the Home screen, select Sonar > Sonar Setup > Depth Line > Show.
2.  Touch and drag the reference line to set the depth of the line.
Showing the A-Scope

The A-Scope is a vertical flasher along the right side of the screen that shows instantaneously the range to 

targets along a scale. 

From the Home screen, select Sonar > Sonar Setup > A-Scope > on.

The picture advance setting allows the sonar picture to advance faster by drawing more than one column of 

data on the screen for each column of sounder data received. This is especially helpful when you are using 

the sounder in deep water, because the sonar signal takes longer to travel to the water bottom and back to the 

transducer.
The 1/1 setting draws one column of information on the screen per sounder return. The 2/1 setting draws two 

columns of information on the screen per sounder return, and so on for the 4/1 and 8/1 settings.
1.  From the Home screen, select Sonar > Sonar Setup > Pic. Advance.
2.  Select a picture advance setting.
Showing Overlay Numbers

You must have a water-speed sensor or a speed-capable transducer to show water-speed information, and 

you must have a water-temperature sensor or a temperature-capable transducer to show water-temperature 

information.
You can set water temperature, unit voltage, water speed (if your transducer is capable), and navigation 

information to appear automatically on the Sonar screens. The navigation information always includes GPS 

speed and GPS heading, and includes bearing and off-course information while navigating.
1.  From the Home screen, select Sonar > Sonar Setup > overlay Numbers.

  If you select Auto, and if the information is available, the data appears on the Sonar screen.
