Never really paid attention to them.. I think it was Tabdog showing that his detector would find a chain..Again, no attention. This morning ,a "gold diamond ring" pops up.No markings inside, so I don't think it is a real one.....BUT nice to find....Made up for the cold and that extra cup of coffee. Then I see a 24 inch thin rope type chain about three feet away.from the ring site..Didn't even realize it was metal until I picked it up..Vaquero did not register it..I told the machine, "You are supposed to find gold, and you can't even find a silly chain"..At that moment, The V gave me the Raspberry, and sounded off on a surface find ,1997 ten dollar, 1/4 oz coin in a pendant holder Nailed it at a good ten inches.. Was coming up to miss a stick.. I left...Wasn't pushing my luck with the cold, coffee, and 70 year old kidneys..I thanked the detector, and have to send Dave an e mail, thanking him for the excellent job of training that machine,,,,cordially NAD..That was seven hours ago, and I am still in orbit..Come on over, I'll take you for a spin around the Solar System......
