Who has used the electronic geomantic compass of metaphysics?

I used two, one was taken away by the owner and the other was bought by myself. The measurement accuracy is relatively accurate, and the laser positioning is much better than the general compass. After all, it is a fully automatic electronic compass, which is a strange door with eight characters and six hexagrams. Name analysis software, such as my Xuanxuetong, contains hundreds of Feng Shui cases and hundreds of strange eight-character cases, which can be discussed by experts. What I like best is that it has the functions of locking the compass after sitting down, flying stars automatically and so on, all of which are good. Unfortunately, the battery can only be recharged in a few days. If you go up the mountain to find a dragon to find a hole, you still need to bring an extra battery. Once I accidentally fell into the water and the LCD screen broke. They helped me change it for free, and the service attitude was first-class.
