To those of you who have used the Minelab X-T 70 with the 6" DD HF coil on very fine gold, could you give me the readings that you received on that kind of gold. A relative bought a very small vial of gold at a show and when I later took a reading on it, it only read "2" which goes against everything I've read and heard on what fine gold should read when using the above combination. Thanks, Mtnmn
