Show/Hide Pointer —allows you 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 map pointer does not move
off the paused screen and cannot show an area that has scrolled off
the screen. The depth is updated while the screen is paused, but
the unit does not show any new sonar data until the standard Sonar
Page is resumed. You can see a discontinuity from where the sonar
information stops to where it starts again.
