Hiding a Geocache

Mike and his family had so much fun on their first geocache outing, that they decide to create a
geocache of their own!
The family decides to hide the cache along a public trail near 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 PN-40. 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. Using the keyboard, enter the comment
information ("Hid cache under pile of sticks."), 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
waypoint 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.
