so you can see that the destination is to your west. Your current facing is
north (a 294º heading) toward an address 355º (bearing) away. If you were
navigating to a waypoint, the waypoint's icon would appear on the edge of
the compass rose, indicating the proper direction. An information box on
this screen indicates the destination is 0.67 miles away.
Calibrate Compass
To find your heading, the iFINDER uses a sensor that detects the mag-
netic field in the area. This field can be affected by any large object, par-
ticularly by metallic items such as your car or the barrel of your rifle.
Over time, all these variations gradually interfere with the iFINDER's
measurements, and will result in poor performance by the compass.
In order to keep your iFINDER reporting accurate compass headings, all
you have to do is calibrate it when you begin to notice this deterioration. To
do this, use the
C ALIBRATE C OMPASS
command on the Compass Page menu.
