Compass
The eTrex 30 has a 3-axis, electronic
compass.
You can use a bearing pointer or a
course pointer to navigate to your
destination.
TIP: When the device is using the
automotive profile, the compass
displays GPS heading, not magnetic
heading.
Calibrating the Compass
notice
Calibrate the electronic compass
outdoors. To improve heading
accuracy, do not stand near objects that
influence magnetic fields, such as cars,
buildings, or overhead power lines.
