Many present day compasses incorporate a baseplate and protractor Resource, and are referred to variously as "orienteering", "baseplate", "map compass" or "protractor" patterns. Such a compass utilizes a individual magnetized needle inside of a rotating capsule, an orienting "box" or gate for aligning the needle with magnetic north, a transparent foundation made up of map orienting strains, along with a bezel (outer dial) marked in levels or other models of angular measurement.

The orienting strains in the base with the compass dial are then rotated to align with actual or real north by aligning them that has a marked line of longitude (or perhaps the vertical margin on the map), ignoring the compass needle fully.

A gyrocompass is similar to a gyroscope. It is a non-magnetic compass that finds true sepatu compass north by making use of an (electrically run) speedy-spinning wheel and friction forces so as to exploit the rotation with the Earth. Gyrocompasses are commonly utilised on ships. They've got two principal positive aspects above magnetic compasses:
