Great another large coil, for me at least not sure about the rest..but I am done buying the next and up and coming " new " coil without real tests. I don't mind the manufacturer doing them neither, but to see words written on an advertisment means nothing to me. Make a coil, do some extensive depth tests with multi ounce nuggets at depth. Most of us have used many of the coils ou there...smalls and bigs, ..if its new and great, prove it. This coil sounds interesting but will it get the 1- 5 ounce nugget deeper than all the others...? If it does, than it will be a succeful coil for Detech and users in the field. I hope Detech and for that matter Nuggetfinder and Coiltek are listening..For now, I am waiting for reviews on 2 coils before I make a descion to buy, one is the X-Coils form Russia...for the GPX...and the other is the Detech 18" CC coil. Don't mean to rant but dang all the coils these days are comparable to the other...one does not have much over the other brand if going head to head for a particualr size...what we need is a coil that goes deeper than the others for the biggies.
