Is there really an electronic geomantic compass? What are its uses?

The landlord asked about the electronic geomantic compass. First of all, the electronic compass is really a good thing, without any additional resources. As long as it is powered on, it can indicate the direction, thus solving the problem of direction identification in rainy days, dark nights and strange places, and it may save people's lives at critical times.

As for the electronic geomantic compass, there is nothing more than an expert who has added the function of indicating geomantic direction on the basis of the electronic compass. In the final analysis, it has labeled ignorance as a scientific and technological label. It must be said that this is completely a deceptive tool.
