In case the hiker has become following the right path, the compass' corrected (accurate) indicated bearing really should closely correspond to your genuine bearing Formerly obtained through the map.
Soldier utilizing a prismatic compass to receive an azimuth Compass navigation together with a map (terrain Affiliation) needs another technique.
