We are planning to purchase a brand new apartment, the building is still under construction. I have already tried all kind of compasses, including luopan, but have got all different results; it looks like like the compasses go crazy. Just for a record, I'm not a novice to using a compass. Mind you, most of the compass readings show NW more or less, but very inconsistent): sometimes it's NW1 (pearl string in period 8), then it's either NW2 or NW3. What's going on, please? What would be your advice in this case, please?
