The other two methods provide a full range of navigation data and work
with both the Map Page and Navigation Page. The only difference be-
tween them is "navigating a trail" follows a trail forward (from start to
end) while "backtracking" follows a trail in reverse (from end to start.)
When hiking at walking speed with a hand-held GPS, we often just use
visual back trailing because it is a bit better at following each little
turn on a foot path. At faster speeds, such as the highway or on the wa-
ter, the Navigate Trail and Backtrack Trail commands are handy.
Visual Trailing
1. On the Map Page, zoom (
ZIN
or
ZOUT
) so your flashing trail is visible.
2. Begin moving and watch the Map Page. Simply walk or steer so that
your current position arrow traces along the trail you have just made.
Tip:
Generally, when using this method, the smaller the zoom range, the
more accurately you will be able to steer along the trail.
