Using the Pointer on the Sonar Page
You can display the pointer (arrow) to reference sonar items and mark underwater
waypoints. This makes it easier to nd and use an object such as a stump as a
future shing 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. Discontinuity is possible from where the sonar
information stops and where it starts again.
