Re: Question on 8" coil
I have two 8" concentric coils a Ferret and Excelerator model your get max 8" depth, I bought two to see if there was more depth, but it will pick through trash great, you raise it 2 inches above the ground and now your searching with the point of the detection cone. I'm amazed how many times coins come up with 2 or 3 nails mixed, but again your depth is only max 6" with this method. They should of made a 12" concentric coil.
