A fellow Ringfinder received a call to look for the Diamond stud earring. He didn’t find it. I told him I could hunt with my XP Deus 1 with my HF coil at 74 kHz . He gave me the map as to where it was lost. I notched out every signal that could not be the item and found it shortly. The earring had just been given as an anniversary present 2 days before. I told her to get it insured.
