What are the numbers on an At Pro for a lady's white gold class ring? I tried searching for threads, but it didn't come up with anything. I have a lady that lost her ring 40 something yrs ago in a flower bed and I said I would try and find it for her. I'll be searching in the front of the home, by the highway. The lady doesn't own the property anymore. But I think we can get permission...I just don't want to do more plugs than I have to...I think there want be a whole lot of trash? but being beside a rural road who knows. Thanks for any help...Resp. Donnie Johnson
