Add a Waypoint Target or Trolling Grid
The Waypoint Target shows a target consisting of concentric circles in various distance ranges
centered on the waypoint you choose. The Trolling Grid shows various distance ranges in grid
format from the waypoint you choose. The trolling grid can be used as a guide when trolling
around a waypoint.
Add a Waypoint Target: From the Waypoints submenu, select Target, and press the RIGHT Cursor
key to display the saved waypoints list. Select a waypoint and press the RIGHT Cursor key.
Add a Trolling Grid: From the Waypoints submenu, select Grid, and press the RIGHT Cursor key to
display the saved waypoints list. Select a waypoint and press the RIGHT Cursor key. The grid can
also be rotated to any heading by adjusting the Grid Rotation setting on the Navigation Menu Tab.
Remove Target or Trolling Grid: Press the MENU key once, and choose Remove Target or Remove
Grid from the Navigation X-Press™ Menu.
NOTE: Only one waypoint can have either a target or a grid applied to it 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 are 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.
