Professional geomantic compass, according to the size, content and material, the price ranges from several hundred yuan to several thousand yuan. It's all different
I suggest you have a look at the Jiyitang compass, which is cost-effective, good in workmanship and accurate. I am using this brand of compass myself.
Don't say I am advertising. I still have great feelings for Wuhan. I lived there for many years. And the compass of Jiyitang is really good.
I hope I can help you.
