Trails

A trail, or plot trail, is a string of position points plotted by the M52 as
you travel. It's a travel history, a record of the path you have taken.
Trails are useful for repeating a journey along the same track. They are
particularly handy when you are trying to retrace your trip and go back
the way you came. On the screen, trails are represented by a flashing
line extending from the back of the current position arrow.

Creating and Saving a Trail

The M52 is set at the factory to automatically create and record a trail
while the unit is turned on. The unit will continue recording the trail
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 M52 begins recording the trail over itself.
By default, the trail flashes once a second, making it easier to see against
the plotter's background. With the default auto setting, the M52 creates a
trail by placing a dot (trail point) on the screen every time you change di-
rections. (The methods used for creating a trail and the trail update rate
can both be adjusted or even turned off. See Sec. 8 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 M52 automatically creates
and begins recording a new trail.
