Have the new 5 x 8 DD coil on my AT-Pro and took it hunting this weekend. 5 quarters, 7 dimes, 3 nickels, 57 pennies but one of those pennies was a 1905 Indian Head! Found it in the sandy soil of a park. Also hit a large sterling men's ring with a black onyx setting. Also found a Hot Wheels Sho Stopper and my required quota of junk. The IH flat took me by surprise given the setting and it's in great shape. I have to think it's a recent drop but who knows? One of these days I'll learn enough about our camera to post some pics...
