Navigating Trails
There are three methods for following a trail: visual trailing, navigating
a trail (forward) and backtracking a trail (backward). Try each method
to see which you prefer.
Visual trailing is the simplest method. It uses only the Map Page and
requires no menu commands at all. The technique works the same if
you are running a trail forward (from start to end) or backward (from
end to start.) However, visual trailing provides no navigation informa-
tion during the trip, such as the time to your destination.
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 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 made.
Tip:
Generally, when using this method, the smaller the zoom range, the
more accurately you will be able to steer along the trail.
