until the length reaches the maximum trail point setting (default is 2,000, but the unit can record trails 9,999 points long). When the point limit is reached, the unit begins recording the trail over itself.

With the default auto setting, this unit creates a trail by placing a dot (trail point) on the screen every time you change directions. The methods used for creating a trail and the trail update rate can both be adjusted or even turned off. See Sec. 5 for Trail Options.

To preserve a trail from point A to point B, you must "turn off" the trail by making it inactive before heading to point C or even back to point A. When the current trail is set inactive, the unit automatically creates and begins recording a new trail.
