I was contacted by a couple this past weekend that had lost their engagement/wedding band set in their front yard. They had looked for it for several days themselves using a metal detector, but he admitted he didn’t know how to use it. Although he did manage to find one part of the ring, but not the other half. The ground there was literally saturated with metallic trash so I knew the search could be difficult. I was initially told the ring was silver, so I concentrated on the high tone that silver makes. I like to hear all the tones as well to make sure I don’t accidently discriminate out a good target that is close to junk. After searching a fairly small area for around 40 minutes, no ring, and I was running out of options. That’s when their jeweler called back, (he had the other half of the ring), and said the ring was not silver, it was white gold, (I had asked them to check). During my search I was ignoring the low tones that white gold makes since that is the same tone that foil makes. So I searched the same area again, and in around 5 minutes I got a 12.02 on my CTX. The ring was hiding in a bowl shaped depression totally covered under the grass.
