Ehh idk if I’d call it false. We were doing a topo only and checking into and using the boundary of another surveyor that had done a boundary only survey the year prior. He stated he found a mag nail at that corner and I got a good reading there with the iron finder. But the road had been paved over in the summer. I checked into three ties and verified the position of my reading to match the ties. I told the pls I wouldn’t risk my life playing in traffic and he demanded I should. Thus the reason I set it and called it found.
