North Reference; Waypoint Proximity Flags (Advanced) - Humminbird 688ci HD DI Operation Manual

North Reference allows you to have bearings displayed with one of two
orientations: True North or Magnetic North.
Waypoint Proximity Flags allows you to display or hide waypoint flags for the
ten closest waypoints to the boat or active cursor. The flags show the distance
from the boat (or active cursor) to each waypoint.
Waypoint Proximity Flags are also influenced by the zoom level and boat speed.
The flags are only displayed if the chart range is less than .5 sm and the boat
is traveling less than 15 mph.
