9X12 Conc. Coil
- Thread starter Allan
- Start date
I have only been using it. It is great for coin & jewellery hunting, both on land and in the water. Because of its large footprint, it covers a large area in less time. And because it's a concentric coil, it doesn't have such an affinity to bottle caps as a DD coil. It works great in my soil. however, as a rule, a DD punches deeper in mineralized soil, and the smaller search area can isolate targets better. I tend to pinpoint off the front inner toe of the coil.
