A compass is an instrument used to determine the direction or position of something, such as the magnetic field strength, relative to a fixed point or a defined position. A compass is usually a handheld instrument, but may be a fixed instrument attached to a support, such as a pipe.

This learning and free compass app explains everything you need to know about compasses (magnetic and gyro types). Variation, deviation, and gyro error are clearly explained in the theoretical section and practically applied in the calculator section.

The compass can be used to determine the position and direction of something, such as the north, south, east, and west directions, or the magnetic north and the geographic north.

A compass can be used as a tool for finding the direction of a destination or for finding the way to a starting point.

The compass can be used for finding the position of a device or object, such as a phone, a car, a house, a desk, a bed, or a tree.
