I was using my CTX3030 with the 17 inch coil, running in fast, ferrous coin, and auto sensitivity +3.
Now I know that in ground signals are different to air tests, but my CTX never picked up the ear ring when waved across the coil in either open or closed? Although it did show a number on the screen in the closed position, but no sound at all
So what settings do you use for smaller non coin gold items.
