Had a successful early morning hunt at a local park in a town that I work in. Found the usual clad that one would expect to find. What was unexpected was finding two James Avery rings within 15 minutes of each other, 30 minutes after starting. After that 1 little wheat to end the day. I was using the Coiltek 15" coil, the big ring was giving a VDI of 38, the smaller ring hit at 31, both were shallow. For a big coil, this thing pinpoints extremely good and will hit coins on edge with no problem.
