ADD A WAYPOINT TARGET OR TROLLING GRID
(987c SI Combo models only)
Add or Remove a Waypoint Target: From the Waypoints submenu (accessed from the
Navigation main menu), 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™ 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.
Add or Remove a Trolling Grid: From the Waypoints submenu (accessed from the
Navigation main menu), 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™ 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.
