Displaying a Saved Trail
The trail is automatically displayed in Easy Mode by default. Trail display can
be selectively turned off and on only in Advanced Mode.
Navigating or Backtracking a Trail
There are two methods for following your back trail. The simplest requires no
menu commands at all, but provides no navigation information during the trip,
such as the time to your destination. The other requires only three key strokes
and provides a full range of navigation data. Try both methods and see which
you prefer. When hiking at walking speed, we often just use visual back trailing
because it is better at following each little turn on a foot path. At faster speeds,
such as the highway or on the water, the Navigate Trail command is handy.
Visual Back Trailing
1. On the Map Page, zoom (
ZIN
or
ZOUT
) so your flashing trail is visible.
2. Begin moving and watch the Map Page (or Navigation Page, if you prefer).
Simply walk or steer so that your current position arrow traces along the trail
you have just made.

NOTE:
If you are already located at or near the
beginning of your back trail, the arrival alarm will
go off as soon as you hit Enter. Just press
EXIT
to clear the alarm and proceed.
On the map, your original trail is visible as a flashing
solid line, along with a roughly parallel dotted line indicating the back trail to
follow. The map contains a steer arrow in the lower right corner. This arrow
shows you where to steer to reach the next waypoint on your back trail.
The Navigation Page will also show the trail line and a bearing arrow, which
points to the next waypoint on the trail.
As you travel, the arrival alarm will go off when you near a trail waypoint, and
the steer arrow (on the map) and bearing arrow (on the azimuth ring) will swing
around and point to the next trail waypoint. Press
EXIT
to clear the alarm.
