I have used my stock coil for several years. I just recently purchased a whites 6 by 9 elliptical coil. I think it is an older whites coil, it is white, and the newer 6 by 10 is black. I will recieve the the coil in a week. Could you give me any advice this type of coil, I have read many different comments, like the depth is not accurate, it is hard to zero in on targets. Is their a better way to sweep the coil, slow or fast. Please any comments would help. I have only detected with the 950 and have found many coins and jewlery. I hope the 6 by 9 will helpful in trashy areas.
