How to learn to use a compass

The use of the compass is as follows:

1. First, open the compass table, loosen the brake screw, and let the magnetic needle rotate freely.

2. Then put the compass on your chest and aim the upper level of the compass at the measured object. Then, rotate the mirror so that both the object and hyperopia are reflected in the mirror, and the object, the nearsighted tip of hyperopia and the center line of the mirror are located on a straight line.

3. When the magnetic needle stops swinging, you can directly read the numbers on the circular dial pointed by the magnetic needle, or press the brake screw to read them again.

The compass has four basic directions: southeast, northwest and northwest. The pointer of the compass generally points to the south, and then turn the inner disk of the compass to make the pointer coincide with the red line below Tianchi, so that the degree to which the fishing line on the surface of the compass is pressed is the degree to be measured.

Next, keep the compass level to determine whether the compass is level. You can observe the bubble height of the compass. When you see the bubble in the middle of the compass, it is horizontal.

Geomantic omen is to find the most suitable position or time for a specific person or thing through the rotation of a magnetic needle.
