Add a Waypoint Target or Trolling Grid
Add or Remove a Waypoint Target: From the
Waypoints submenu, select Target and press the
RIGHT Cursor key to display a list of waypoints. Select
the waypoint you want to target. A target consisting
of concentric circles centered on the selected
waypoint will appear on all of the navigation views;
the target shows various distance ranges from the
targeted waypoint. To remove the target, choose
Remove Target from the Navigation X-Press
TM menu.
Add or Remove a Trolling Grid: From the Waypoints
submenu, select Grid and press the RIGHT Cursor key
to display a list of waypoints. Select the waypoint to
which you want to add the grid. The trolling grid will
appear on all of the navigation views, and can be
used as a guide when trolling around a waypoint.
The grid can be rotated to any desired heading using
Grid Rotation from the Navigation Main menu. To
remove the trolling grid, choose Remove Grid from
the Navigation X-Press
TM menu.
NOTE: Only one waypoint can have either a target or a grid at one time. If you apply a target
or a grid to a new waypoint, the original waypoint will lose its target or grid.
NOTE: The spacing of the rings on the waypoint target and the spacing of the grid lines on the
trolling grid is the same as the length of the scale bar on the left edge of the display. Zooming
in or out will decrease or increase the spacing, respectively.
