• 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 pauses. The pointer does not move off the paused display and cannot
show an area that has scrolled off the screen. The depth is updated 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
discontinuity 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 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. The data window at the top of the screen displays the cursor’s depth, coordi-
nates, and bearing and distance from your current position.

3. Press ENTER/MARK. The New Waypoint page appears with the waypoint’s coordinates, default

three-digit name, and pointer depth automatically ﬁ lled in.

4. To change the name, symbol or depth, highlight the appropriate ﬁ eld and press ENTER. Make your

changes and press ENTER when done.

5. When done, move the ﬁ eld highlight back to the ‘OK’ prompt and press ENTER.

6. To return to the standard Sonar Page, press QUIT; or press MENU, then highlight ‘Hide Pointer’

and press ENTER.

• Show/Hide Numbers — toggles showing/hiding the data ﬁ elds on the sonar display.

• Change Numbers — allows you to specify the type of data displayed in each data ﬁ eld. For detailed

instructions on changing the data ﬁ elds on the Sonar Page, see pages 26-28.
