onto your locked bearing course.
the current bearing is 94°
your current bearing is 120°.

SET THE DECLINATION

Declination is the angle between where a compass needle
points (magnetic North Pole) and the true North Pole.
The declination angle can vary from 0-30 degrees East
(E) or West (W) and can be found on most maps or on
the Internet.
When you set the declination angle on the compass
you compensate for the difference between true north
and magnetic north. This makes the compass reading
more accurate.
