DeLorme PN-20 - Manual (Page 15)

14
In the scenario below, Tom, a bird watcher, uses the Earthmate GPS PN-20, aerial imagery, and the
Earthmate GPS PN-20 Online Map Center to prepare for his expedition.
Before Tom leaves for his trip, he uses the Earthmate GPS PN-20 Online Map Center to download
additional map data so he can get satellite and aerial views of the area where he’ll be. This is helpful
to Tom because he has heard that the bird population is greater near the swamp land. With the aerial
and satellite data available from the Online Map Center, Tom can see the geological formations in his
bird watching area before he leaves, giving him a greater idea of where he should spend his day.
1. Visit http://data.delorme.com to download the area where you will be bird watching.
Once the map of the location is saved on the Earthmate GPS PN-20, Tom leaves for his bird watch-
ing trip. When he arrives at the location, he parks his truck, turns on the Earthmate GPS PN-20,
waits until he gets a 2-D or 3-D fix, places a waypoint to represent the parking lot, modifies his
tracking settings, and then turns on Track recording.
2. Press and hold the Power button to turn on the Earthmate GPS PN-20.
3. Press the Mark button on the device to place a waypoint at the parking lot location and press
ENTER.

a map and compass with you

batteries in your Earthmate
GPS PN-20 are low.

you want to record a lot of
detail. Use the Distance option
if you are going to make many
steps along the way.
