Humminbird 1157C Fish Finder User Manual


 
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.
