of two orientations: True North or Magnetic North.

Grid Rotation
Grid Rotation allows you to set the orientation of the trolling grid
in degrees, where a setting of 0° displays a standard North, South, East, West alignment. See
Waypoints for information on how to set a Grid.

2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Grid Rotation setting. (0°
to 89°, Default = 0°)
Trackpoint Interval
Trackpoint Interval allows you to select the time period between
trackpoints. The current track can only contain up to 2000 trackpoints, so longer time periods cause
the track to extend back further in time, but will be less detailed.
NOTE: Trackpoint Interval works in conjunction with Track Min Distance. Both conditions must be met
before a trackpoint is added to the current track.
To change the Trackpoint Interval setting:
1. Highlight Trackpoint Interval on the Navigation main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Trackpoint Interval setting.
(1 second, 5 seconds, 10 seconds, 15 seconds, 30 seconds or 60 seconds, Default = 15
seconds)
NOTE: During slow travel or drift, setting both Trackpoint Interval and Track Min Distance to small
values will allow you to increase the track resolution.
