tion changes as you move around the earth. Magnetic North is the direction in which a
compass needle points.
The Geko 201 bearings will correspond to the compass if the Geko 201 is set to
magnetic north. Due to errors introduced when map makers fl atten the earth’s sphere onto
paper, not all of the grid lines drawn on the map point exactly to the north pole, so the
north indicated by the grid lines is called ‘Grid North’. The difference, however, is usually
small enough that ‘Grid’ north can be considered the same as True North for traveling on
land. If necessary, manually correct for the difference between Grid North and True North. If
you select ‘User’ for North Reference, the
‘VARIATION’
fi eld is highlighted for you to edit the
declination.
