Points of the compass "X "al" Y" (X to Y) or "X "per" Y" (X by Y). There are no irregularities to trip over; the closest principal wind always comes first, the more distant one second, for example: north-by-east is ""Quarto di Tramontana verso Greco""; and northeast-by-north is ""Quarto di Greco verso Tramontana"". The table below shows how the 32 compass points are named. Each point has an angular range of 11.250 degrees where: middle azimuth is the horizontal angular direction (from north) of the given compass bearing; minimum is the lower angular limit of the compass point; and maximum is the upper angular
Compass secular variation. The effect of this means a map with the latest declination information should be used. Some magnetic compasses include means to manually compensate for the magnetic declination, so that the compass shows true directions. There are other ways to find north than the use of magnetism, and from a navigational point of view a total of seven possible ways exist (where magnetism is one of the seven). Two sensors that utilize two of the remaining six principles are often also called compasses, i.e. gyrocompass and GPS-compass. A "gyrocompass" is similar to a gyroscope. It is a non-magnetic compass
