Trolling Grid Rotation
Settings: 0° to 89°, Default = 0°
Trolling 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.
Track Color Range
Settings: 50 to 3000* feet or 20 to 1000 meters
[International Units only], Default = 50 ft, 20 m
Track Color Range
allows you to set the depth range that will be displayed
as black, the deepest depth, when Color By Depth is selected as the style for
the current track (see
Navigation Menu Tab: Current Track
).
*NOTE:
Only an optional-purchase transducer with a 50 kHz frequency will allow
you to track to 3000 feet.
