I had a guy stop by last summer (he actually grew up in the old farmhouse) and asked if he could swing for a while. Can't remember the detector (it was a White's), but he'd had it about 6 years, cost him $600, and had a display that showed different coins. The detector kept saying he found this coin and that coin, but there were NO coins.
What stands out in my mind is HOW he was swinging. It was rather fast and he skipped a LOT of ground.
Read an article some time back about the search shape of detectors - maybe it was on another gold/treasure site? Anyway, the illustration showed that some detectors view(?) a wide area near the surface, but taper off to a tiny point at maximum depth. That would certainly explain why sometimes you hit a target and sometimes you don't.
Add that to the speed of the swing - if too fast, then the electronics may not have time to sense an object, discriminate the surrounding earth, try to distinguish what the object is, and finally tell you that something is there.
What was funny about this guy is that his machine told him there was a large silver coin. ...Almost seemed like he was searching for a particular item, but... Anyway, he dug about 9" and pulled out a piece of copper tubing. He left it on the steps, and next time he stopped by, I reminded him not to forget his treasure!!
