The Nokta/Makro Anfibio and the 7" concentric coil make a score.

I was able to get out for a short time and learned another valuable lesson. The 7" concentric coil from Nokta/Makro is awesome on their detectors. I used the 7" on the Anfibio in a local yard and found a well worn standing liberty quarter, and a 1920 mercury dime. The lesson learned is that the Anfibio separates good target just as well as separating iron from non-ferrous targets. What I mean is that in the 99 tone mode, both coins that were in the same hole gave two distinct ultra sweet high tones.
