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.
Track Min Distance
(Advanced)
Track Min Distance allows you to set a minimum distance of travel before a trackpoint is added
to the track. The Track Min Distance menu choice is only available when User Mode is set to
Advanced (see Setup Menu Tab: User Mode).
NOTE: Track Min Distance works in conjunction with Trackpoint Interval. Both conditions must
be met before a trackpoint is added to the current track.
NOTE: See Setup Menu Tab: User Mode in your Fishing System Operations manual.
To change the Track Minimum Distance setting:
1. Make sure you are in Advanced User Mode, then highlight Track Min Distance on the
Navigation main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Track Min Distance
setting. (1 to 300 feet or 1 to 100 meters [International Units Only], Default = 16 ft, 5 m)
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.
