Using the Pointer on the Sonar Page
You can show the pointer (arrow) to reference sonar items and
mark underwater waypoints. This makes it easier to find and use
an object such as a stump for a future fishing location. When using
this feature, the Sonar Page pauses. The depth continues to update
while the display is paused, but the unit does not show any new
sonar data until the Sonar Page resumes scrolling. You might see a
discontinuity from where the sonar information stops and where it
starts again.
To
mark an underwater waypoint:
1. From the Sonar Page, press MENU, highlight Show Pointer,
and press ENTER.
2. Use the ROCKER to move the pointer to the location you
want to mark, and press ENTER. The New Map Waypoint
page appears.
3. To change the name, symbol or depth, highlight the
appropriate field and press ENTER. Make your changes, and
press ENTER.
4. When you are done making changes, highlight OK, and
press ENTER.
5. To return to the standard Sonar Page, press QUIT; or press
MENU, highlight Hide Pointer, and press ENTER.
Setting Up Sonar
Use the Sonar tab on the Main Menu to set up the Sonar Page.
To access the Sonar Tab:
1. Press MENU twice to open the Main Menu.

Main Menu—Sonar Tab
Fish Symbols—select how the Sonar Page shows underwater
targets and background information. Select Off to display all of the
available information about the underwater environment. Select a
fish symbol to show only the information related to that symbol.
Water Type
—select the proper water type you are boating in.
Because sound waves travel through fresh and salt water at different
rates, it is necessary to select the Water Type to ensure accurate
readings on the unit.
