Sonar Page Options
The GPSMAP 168 Sounder’s Sonar Page features a menu page that provides access to additional
functions and to layout and data fi eld options.
To display the Sonar Page options:
1. Press MENU.
To select a menu option:
1. Use the ARROW KEYPAD to highlight the desired option and press ENTER/MARK.
The following options are available:
• Show/Hide Pointer— allows you to reference sonar items and mark underwater waypoints. This
makes it easier to fi nd and use an object such as a stump for a future fi shing location. When using this
feature, the Sonar Page will pause. The pointer will not move off the paused display and cannot show
an area that has scrolled off the screen. The depth will continue to update while the display is paused,
but the unit will not show any new sonar data until the standard Sonar Page is resumed. You may see a
dicontinuity from where the sonar information stops to where it starts again.
To mark an underwater waypoint:
1. From the Sonar Page, press MENU, highlight ‘Show Pointer’ and press ENTER/MARK to pause
the screen movement.
2. Use the ARROW KEYPAD to move the cursor onto the target (underwater drop off, stump, etc.)
you want to mark. A data fi eld will appear with the cursor’s depth, coordinates, and bearing and
distance from your current position.
3. Press ENTER/MARK. The New Map Waypoint page will appear with the waypoint’s coordinates,
default three-digit name, and depth automatically fi lled in.
4. To change the name, symbol or depth, highlight the appropriate fi eld and press ENTER/MARK.
Make your changes and press ENTER/MARK when done.
5. When done, move the fi eld highlight back to the ‘OK’ prompt and press ENTER/MARK.
6. To return to the standard Sonar Page, press QUIT or press MENU, highlight ‘Hide Pointer’ and
press ENTER/MARK.
Use the ARROW KEYPAD to point to
an underwater target.
