Geomantic compass, square or round?

the geomantic compass should have an outer garden and an inner garden to be useful. Few people use the garden now, and it is not easy to stand upright. Square disk measurement is accurate. Beginners buy a medium compass for Feng Shui, and a seven-to-eight-inch comprehensive disk is the best, and ternary and triad can be used. Don't buy a unique compass yet. If you have the foundation of the Book of Changes, you can learn Sanyuan and Xuankong first. There are many mountains and waters in the south, and there are many geomancers who use the triad school. Those geomancers who have good knowledge have learned several methods and used them flexibly. Buying a small compass has a small capacity, and all the commonly used compasses for 3 ~ 4 floors are available. And the small compass is not easy to use and has a big error.
