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, while "back-
tracking" follows a trail in reverse.
When hiking at walking speed with a hand-held GPS, we often just use
visual back trailing because it is better following each little turn on a
foot path. At faster speeds — like traveling on the highway or on the
water — 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. Simply walk or steer so your
current position arrow moves 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.
