If a magnetic north bearing or compass bearing is wanted, the compass must be altered by the amount of magnetic declination prior to utilizing the bearing to ensure each map and compass are in settlement.[40] During the presented example, the massive mountain in the next Image was chosen as the focus on location around the map. Some compasses enable the scale to become altered to compensate to the local magnetic declination; if modified properly, the compass will provide the accurate bearing in lieu of the magnetic bearing.
