It does sound like you have a detector issue and not a search coil problem. We'll check it out when we get together this coming Saturday. I'll take a look at it, and you can also get a scenic tour in to a gold mining era ghost town to check out some other detectors as well. Have a chance to see what kind of "Iron contaminated sites" we typically encounter.

It will be easy to figure out why I love smaller-than-stock coil and have fine-tuned my Regular-Use Detector Outfit and search coil assignments.

See you soon.
