Using the ‘Average Location’ Option
You can average location calculations to create a more accurate
waypoint by reducing the effects of GPS location errors. It is important
to remember that when you average a waypoint from the Waypoint
List or create a new waypoint without actually being at the site of
the waypoint, the location for that waypoint will be changed to your
current GPS location.
To Average a Location:
1. With the waypoint page displayed, press the MENU key to display the
Waypoint Option Menu.
2. With ‘Average Location’ highlighted, press the ENTER key to display the
‘Average Location’ Page.
3. Observe the ‘Estimated Accuracy’ fi eld and press the ENTER key with
‘Save’ highlighted when the estimated accuracy reaches the desired
value.
4. Press the CLEAR key to cancel ‘Average Location’ and leave the
waypoint
unchanged.
