Grandkiddos are here this week so I did a seeded hunt yesterday in my back yard. They had a blast! This morning Annie & Logan were back at it cleaning up the last hidden coins when Annie says she has a good signal. I look up and she has wandered out of the hunt area...but she is right..it IS a strong signal even with the disc turned up. Up out of the dirt comes this item. Have no clue what it is....any ideas?
