MAGNETIC COMPASS
2-8
When not being used, the magnetic compass must be stored
in and upside-down position to prevent unnecessary wear on
the compass pivot and jewel.
NOTE
The arrow on the compass dial always points to magnetic
"NORTH."
Items which contain iron or steel, and other types of
compasses may cause the MC-1 magnetic compass to
give incorrect readings.
The type MC-1 pocket magnetic compass is a very important aid
in ascertaining your direction of travel. The compass is equipped
with a transparent plastic top, a long line (lubber line) for
determining the directional course reading, and two lanyard
attaching rings located on the bottom of the compass case for use
in attaching a retaining lanyard. To use
