It was a beautiful day in Pittsburgh today and it was my first day with my new 505, I needed to see if I made a good choice?.quite simply, I think I had a GREAT DAY. My machine went beyond my expectations and I ended a three hour outing with $1.54. I found 5 quarters, 1 dime, two nickles and 9 pennies (one wheatie).There were a thousand beeps that occurred and since I knew not the chase them all, I would start doing notch discrimination to get better reads. If I kept getting good sound, down on one knee I went. Of the 12 or so deep holes I dug, damn if there wasn't a coin in there most every time. I marveled at each one, even the penny digs. My day at the sled hill could have been better if the find area made better sense to me? Almost every coin was at the very bottom of the hill. Not at the end of the sled run, where I thought they would be?? I can not wait to get to a tot-lot. Can someone also help me with what to clean these quarters with. Two of my find are so dirty that I can't tell if they're silver or clad?
