I bought Shen’s Xuankong Xue (Illustrated Edition) and want to learn some Feng Shui by myself. I don’t know what kind of compass to buy.

If you are a beginner, the automatic compass is of course more convenient, but what should I say? His sensitivity is not strong. In addition, if the indoor magnetic field changes, it will be all over... So I personally recommend using copper and setting the sitting direction when outdoors. Don't use a comprehensive disk. If you are learning Xuankong Feixing, then it is good to use a three-yuan disk, or Li Juming's eight-luck disk, which is easier to use. It’s available on Taobao, but it’s best to check it out after buying it. If you have a professional compass, it's best to compare it. In addition, check whether the scale on the outermost circle is accurate. Use a protractor to check...

Hope this will be helpful to you
