Eagle Electronics Mapping GPS Receiver, 640c manual

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.
