Yet again, if a single is utilizing "legitimate" or map bearings, plus the compass does not have preset, pre-adjusted declination, just one must On top of that incorporate or subtract magnetic declination to convert the magnetic bearing into a genuine bearing. The exact value of the magnetic declination is position-dependent and differs as time passes, even though declination is frequently offered over the map by itself or obtainable on-line from a variety of websites. When the hiker is following the right route, the compass' corrected (correct) indicated bearing should really carefully correspond into the real bearing Earlier obtained within the map.
