You can see iron staining on the coins this site has had 100s and 100s of detectors on it and the coins are still there it was a very slow process of trying to find a coin signal here iron intense iron well have to run the ctx here next year and see what happens .
My friend did find 2 barber dimes here and a bunch of wheat's at another site he found a 1865 Indian in good shape 7 inches deep came in at a solid 17 my ctx read it out of the ground at 12.32 and the coin wasn't even rotten makes me wonder how many Indians I have left in the ground .Since the nox also read it as 17 out of the ground I did get 1 Indian I think it reads 19 on the nox and 12'35 on the ctx it has the full weight of a Indian but can't see anything on it coin is left of the picture I posted sube
