Plumb bobs are always calibrated,,,,,,,,unless it's windy,,,,,,,,unless you're hung over. 😉

Once the patent starts getting broken then it can get dicey. Also, the GLO plat may not line up with the patent. In that case an 80 acre parcel shown ...

@dave-o We have areas of volcanic rock here, it's usually magnetic and makes finding pins more challenging. Sometimes they really set the detector ...
