While going through my park hunt finds, I found this button which is copper that is backed with iron. I will try to find the video of the find.

This is a great example of the "language" that TNSS speaks of.

The copper gave one tone and the iron another. In the end the way the machine reacted gave me enough info to dig.

I would have not dug this with the AT Pro because of the iron audio

If you want to do well with the AT PRO in dense iron, put it in standard coin mode, iron disc at 30, iron audio on. Listen for any non ferrous tone besides the iron grunt. For some reason these same settings do not work in the Pro Modes.
