Track Min Distance
(Advanced)
Track Min Distance allows you to set a minimum distance of travel before a

conditions must be met before a trackpoint is added to the current track.
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

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 Color Range

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).

you to track to 3000 feet.
