I received this as a Christmas present, after much begging!!! We live in San Diego's suburb Pacific Beach and Christmas Day was 70 degrees. We went to the beach about noon and within 1/2 hour I had picked up over $5 in various change. Then about an hour in, I found a ziplock bag that had a ladies metal hair clip, a brush and low and behold, in the bottom of the bag a pair of diamond earrings. Wednesday, after Christmas, we were so curious, we took them to our local jeweler and found them to be a very nicely matched 1/2 carat pair of earrings. What a find! My wife has now officially made this my new 2nd job! The unit is great. The only thing I would recommend is buying headphones because of outside noise influence, it's difficult to hear sometimes. Otherwise.. this thing is GREAT!
