18K Gold earring recovered from front garden

I was asked by Kashif to try and find a small 18 K gold earring that his wife had lost recently, the earring was lost when his wife took off her jumper whilst gardening on the front lawn .

I scanned the other earring , so as to know what sound and numbers I was looking for , and began scanning the area of lawn that the earring was thought to lie in , after 20 minutes of searching I had a solid repeating signal and a corresponding number ( 15 ) on my manticore detector , showing the target was only 1 inch deep in the lawn thatch , after retrieving the small golden earring , I presented it to the very thankful and amazed owner , who had her doubts if something that so small could ever be found and recovered .
