The difference between compass and compass

Compasses and compasses are two different navigation instruments, with significant differences in function and structure.

A compass is mainly used to indicate the geomagnetic direction and is usually designed in the form of a compass. Its structure is relatively simple, and its main parts include a magnetic needle and a dial. The pointing ability of the magnetic needle can indicate the direction, while the dial can show the specific angle. Compasses are widely used in navigation, geodesy, travel and military fields.

A compass, also known as a compass, is a precision instrument used to measure directions and angles. Its main function is to measure the projection direction and angle of ground objects and celestial objects on the ground, thereby determining the direction and height of the target. The structure of a compass consists of a telescope, a reticle and a degree device. When using it, you need to fix it on a horizontal surface, observe celestial objects through a telescope, and read the degrees on the reticle to determine the direction. Compasses have also been widely used in navigation, geodesy, and military fields.

In general, the main difference between a compass and a compass lies in their construction and use. The compass is mainly used to indicate directions and has a relatively simple structure; while the compass is mainly used to measure directions and angles and has a more sophisticated structure.
