I heard you on “Let’s Talk Metal Detecting and Treasure Hunting” with Jon Morgan, and the information you provided was so very helpful! . . .Been hitting old hydraulic areas west of Jacksonville. The coil (5 x 9 Folded Mono Coil) is amazing. Randy M.
Been using your new Miner John Designs 6 x 9 folded mono coil and I have to tell you that I’ve been very impressed. Been able to run at a higher gain and smoother threshold than the original factory coil. It can find the smallest piece of wire, it just surprised the heck out of me. It really has given me the confidence to know I will find gold or anything else if I get my coil over it. Tim M.
