What compass do you use to see Feng Shui?
There are many schools of compass, including three methods, three methods, mysterious method, eight houses method, Gankun national treasure, Longmen Eighth Bureau water method and so on.
Most of the differences between schools are in the scope of use.
As for the number of layers of the compass, the difference mainly lies in whether the disk surface is rich or not.
A compass with fewer layers must have less content, while a compass with more layers must have more content.
If beginners suggest you buy a comprehensive compass, the size can be about 7.5 inches, depending on your needs.
You can have a look at the compass of Taipei Jiyitang, which is an old brand for more than 20 years. The cost performance is very good. The compass made of diamond plate is exquisite, and the price is always the same. It is said that it was made by Taiwan Province Province in Chinese mainland, but I'm not sure about the details. I just think the product is very good. I bought one of their six-pie comprehensive discs and a 7.5-inch comprehensive disc myself.
You can go to their online shop to have a look. I don't quite remember the address.
You can search for "Taipei Jiyitang" in Baidu.
