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 trail is visible.
2. Begin moving and watch the Map Page. Walk or steer so your cur-
rent 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.
