Grid Rotation
Settings: 0° to 89°, Default = 0°
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 Introduction to Navigation: Add a Waypoint Target or Trolling Grid for
information.
NOTE: This feature may appear as either Trolling Grid Rotation or Grid Rotation,
depending on your model.
Trackpoint Interval
Settings: 1 second, 5 seconds, 10 seconds, 15 seconds,
30 seconds, or 60 seconds; Default = 1 second
Trackpoint Interval allows you to select the time period between trackpoints.
The current track can only contain up to 20,000 trackpoints, so longer time
periods cause the track to extend back further in time, but will be less detailed.
Trackpoint Interval works in conjunction with Track Min Distance. Both
conditions must be met before a trackpoint is added to the current track. During
slow travel or drift, setting both Trackpoint Interval and Track Min Distance to
small values will allow you to increase the track resolution.
Track Min Distance
(Advanced)
Settings: 1 to 300 ft, or 1 to 100 m [International Units
only]; Default = 16 ft, 5 m
Track Min Distance allows you to set a minimum distance of travel before a
trackpoint is added to the track.
Track Min Distance works in conjunction with Trackpoint Interval. Both
conditions must be met before a trackpoint is added to the current track. During
slow travel or drift, setting both Trackpoint Interval and Track Min Distance to
small values will allow you to increase the track resolution.
