The most common types of compass errors include magnetic deviation, declination error, and inclination error. Magnetic deviation is a systematic error in which the needle of the compass deviates from true north due to local magnetic fields. Declination error is the difference between the direction of true north and the direction indicated by the compass needle. Inclination error refers to the angle at which the compass needle points relative to the horizontal plane.
