I have only played with the F2 around the house. Took it to a local ball field today as wife wanted me to leave for an hour so she could clean. Was out for about an hour and a half. The F2 loves tabs and doesn't kindly place them in the tab segment. Many hit hard as nickels. But what also hit as a nickel was a 14K gold ring about 3" down. Silver is perfect on the segments. Now if I can just remember what number was displayed.
Very nice snag there man! That ring is about as hard as they get to find...right smack in the nickle/pulltabs! Hats off to you Sir! Well done!
