How to choose feng shui compass?

In ancient China, people discovered the magnetism of matter, thus invented the compass, and on this basis, created a compass for geomantic exploration.

Compass plays a very important role in geomantic omen, which is indispensable for surveying the future of Long Mai and determining the orientation of geomantic omen bureau. But now, after nearly two thousand years of evolution and improvement of various schools, the compass has formed an extremely complex system, with more and more levels, richer meanings of geomantic omen and more and more categories, which has caused certain difficulties in the selection of compasses in modern geomantic omen.

Geomantic compass can be roughly divided into three types: ternary disk, triple disk and comprehensive disk.

The ternary disk, also known as the "Pan Jiang", is mainly characterized by sixty-four hexagrams, which are congenital and acquired. Most of these compasses are used by the rational style in geomantic omen.

Three-in-one disk, also known as "Yang Gong Pan", is characterized by three floors and twenty-four mountains. This kind of compass is mostly used by the situation school in Feng Shui.

Comprehensive plate is a composite plate made by combining the theory and situation of gas. In modern geomantic omen, the theories of qi and situation are mostly combined, so comprehensive boards are often used.

Compass has many dimensions (disc diameter), but in theory, its upper limit is 1 ft 2 inches, and its lower limit is 2 inches and 8 minutes. In practical use, you should try to choose a larger compass, because the bigger the compass, the more accurate it is, and the requirements of the other party in Feng Shui are extremely strict. The so-called "one line is born, one line is dead" and "one line is good or bad" refers to this change. Therefore, the more accurate the compass is, the less likely it is to make mistakes in the process of conditioning Feng Shui.

The compass itself is a very precise tool, so when choosing a compass, we must pay attention to several points: first, the pointer of the compass must be straight, and those pointers that are up and down and skewed must never be used, not only because these situations will cause visual errors, but also because these situations themselves indicate that there is a problem with the magnetic field of the compass, so it is naturally impossible to get a correct conclusion in use.

Second, the red line at the bottom of Tianchi must point directly to the north and south. When the magnetic needle is aimed at the red and black line, the south side should be opposite to the center of the heavenly stem "noon" and the back side should be opposite to the center of the heavenly stem "child", and there should be no difference.

Thirdly, the compass is made of wood, but it must be dry, otherwise the outer disk will be deformed, generally very small, which is difficult to observe with the naked eye, but it is enough to affect Feng Shui measurement. Try not to use metal compasses, especially steel compasses, which are easily magnetized and will inevitably cause problems after long-term use.

Fourth, the compass needle must rotate flexibly and unimpeded. If the magnetic needle does not rotate smoothly, it means that the magnetic field of the compass is disturbed and inaccurate.

These are just some suggestions for beginners of Feng Shui to choose compasses. In geomantic omen, the choice of compass itself is a science, which requires a lot of experience to accurately use and understand the subtlety of compass.
