The family decides to hide the cache along a public trail approximately 10 miles from their home.

Before they can add the cache to geocaching.com, they must get a very accurate coordinate for

the location where they’re hiding the cache. To do so, they must mark a waypoint at the geocache

location and then use the Averaging function on the Earthmate GPS PN-20. When a waypoint is

averaged, a series of GPS readings for the waypoint’s location is recorded and averaged to increase

the positional accuracy of the waypoint.

1. Ensure you have a 3-D signal at the location of the geocache.
2. Press the Mark button. A waypoint is placed at the current GPS location.
3. Highlight the default waypoint symbol and press ENTER. Use the arrow keypad to select the

geocache hidden symbol and press ENTER.

4. Highlight the default label and press ENTER. Enter the new label “Our First Geocache” using

the keyboard, highlight OK, and press ENTER.

5. Highlight the Comment field and press ENTER. Enter the comment information (“Hid cache

under pile of sticks”) using the keyboard, highlight OK, and press ENTER.

6. Highlight the Avg button and press ENTER. The GPS status, coordinates, elevation, number

of readings at the location, and estimated accuracy display. The positional accuracy of the

way-point is increased by the number of recordings. A small estimated accuracy number

indicates that the waypoint is very close to its actual coordinates.

7. Highlight the OK button and press ENTER.
8. Use the arrow keypad to highlight the Save button and then press ENTER.

Once the geocache location point is averaged, they visit www.geocaching.com and create a new

geocache with the averaged coordinate.

Bird Watching

The Earthmate GPS PN-20 is a perfect companion for bird watching. With aerial imagery loaded on the

Earthmate GPS PN-20, bird watchers can see clearings, tree cover, geological features, and more. In

addition, they can use the waypoint function to mark waypoints on the map when they see particular

types of birds. They can also use the track functionality to create a breadcrumb trail while they’re travel-

ing to their bird watching spot and then follow that track back to their vehicle so they do not get lost.
