Well, I finally switched coils w/my Royal Sabre to consider the merits of getting a 5.75" coil and the short hunt settled the matter-gotta have it! The 4" coil is not very deep but sure hits. The find at the top left MAY be something like a roman coin-I'm debating how I'm gonna clean it. It looks like columns in the middle of the coin and was the deciding factor to get the 5.75 coil. The top right target gave a strange signal-turned out to be a magnet! The small fair was one of those traveling thingies, and lasted about. When I get the coil, I'll give it a second time over.
