The detector I use is the XP Deus II with a 9" coil. For ghost town hunting I use the Deus Fast program and modify it to how much trash is present at a ghost town site. For tones I use the pitch option and set that tone to its highest setting. Still experimenting with different settings and programs the detector has to offer.

I have the XP Deus also with both the 9" round coil and the 5"x9" elliptical coil, so the transition to the XP Deus II was easier. Both detectors are very capable for handling iron infested sites.
