To Average a Waypoint

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. You can average a waypoint only at
your current GPS location.
Note: You can also use the Waypoint Detail Menu to begin averaging the selected waypoint. If the
waypoint has already been averaged, the Readings and Estimated Accuracy continue to update,
giving you historical information.
1. Mark a waypoint at your current GPS location but do not save it (for more information, see To
Mark a Waypoint on page 50).
2. Use the arrow keypad to highlight the Avg button and press ENTER. The GPS status,
coordinates, elevation, number of readings at the location, and estimated accuracy display. The
more readings you record, the greater the positional accuracy of the waypoint. A small
estimated accuracy number indicates that the waypoint is very close to its actual coordinates.
