Today I was searching for a 1/2 karat diamond earring with what appears to be a white gold post/stud. Not an easy task, I know. However, it was made even more difficult by the massive power lines along the fence in the backyard. I was unable to turn up my Equinox enough to register anything. I don't know how to manage the EMI, if there is a way to do so. Any suggestions to assist would be appreciated.
