A compass is a commonly used navigation tool that helps people find directions. Here are the steps to use the compass:
Take out the compass and place the compass horizontally so that the pointer is still.
Facing the red hand of the compass, the north pointer, stand up straight.
Find the point of the north end of the magnetic needle, which is where the red needle is pointing, which is north.
Then find the point of the south end of the magnetic needle, which is where the black pointer is pointing, which is the south.
Then find the point of the west end of the magnetic needle, which is where the white needle is pointing, which is the west.
Finally, find the point of the east end of the magnetic needle, which is where the blue needle is pointing, which is the east.
Here are a few things to keep in mind when using a compass:
Before using a compass, it is necessary to check whether the compass is accurate, which can be calibrated by comparing it with other reliable compasses or by using modern navigation tools such as GPS.
The compass needs to be placed horizontally to keep the needle still, and if it is tilted or shaken, it will affect the accuracy of the compass.
When using the compass, it is necessary to stay away from magnetic field interference, such as high-voltage lines, railroad tracks, etc., which can affect the accuracy of the compass.
When using a compass, you need to pay attention to safety and do not use the compass on a moving vehicle or boat to avoid accidents.
In general, using a compass requires a certain amount of skill and experience, but as long as you master the correct method and precautions, you can easily discern the direction. At the same time, it is also necessary to continue to practice and summarize experience in order to better master the skills of using the compass.
