Was out last night hunting in All Metal mode and got a signal said 75. Of course i thought it was a zinc and I don't like digging them. I call them "stinkin' zincoln". I only dig if they sound different or deep. Anyway, this signal would not go up to the 76-77 that I always get so I decided to dig. It was an ear ring. So I wondered if the other one was nearby and began an intensive search. About six feet away I got another signal just about the same number and found another ear ring about the same size and shape but this one was different. So my first two ear rings about five minutes apart but not matching. I thought maybe someone spilled their purse but I found no other jewelry. Can't help but wonder why two different ones so close together.
