Online shopping! There is no need to be obsessed with looking at the real thing. Find an online shop with a big brand and ask if it will be returned within 7 days after sale. Basically, the problem is not big. After receiving the compass, check whether there is any problem, whether the rotation is flexible, and whether the meridian coincides with the seabed. Will this be seen? Let's see if the font on the disc is clear and if the four sides of the compass square are at right angles to each other. In fact, when you look at the compass in the store, you are also reading these contents.
I suggest you take a look at the compass of Jiyitang, which is very cost-effective. At first, several other disciples introduced me to buy Jiyitang, and the more I used it, the more I liked it. Now someone asks me where to buy a compass, and I refer to Jiyitang. Their compass is made by hand, and the quality is exquisite, which is worth seeing. Just search for Jiyitang compass directly in Taobao or Baidu.
