Averaging still can reduce the some of the effect of a temporarily poor DOP.While averaging is going on you can move to the name field and enter the name you wish so that when you have achieved a stable FOM you want you can save the results.
While averaging is going on the unit will display a FOM, figure of merit, number to indicate the probable accuracy of the average to this point.
All units except the aviation models, the etrex, and emap have a man over board (MOB) capability.
This is accomplished by pressing the GOTO key (Nav key on the 76) twice in a row and then hitting enter.
For example naming a waypoint to 001 explicitly will cause the next automatic number to be 002 unless this is in use.
It will automatically increment until it finds an empty number.
