Track Min Distance (Advanced); Track Color Range; Map Datum (Advanced); North-Up Indicator - Humminbird 598ci Operation Manual

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 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).
Map Datum allows you to change the map coordinate system used by the
Fishfinder to match those of a paper map.
North-Up allows you to display the North-Up icon on the screen to indicate the
direction of True North. The icon also displays the Chart Orientation, and it will
change as the orientation and the data source change. To set the Chart
Orientation, see Navigation Menu Tab. Also, see Views: View Orientation.
