I took my Tejon to a tot lot at a school the other night and I can't get over how small of items it will hit on it is a fantastic jewelry hunter. I would be willing to bet that it could find a needle in a haystack. I can't speak highly enough for the Tejon, the more I use it the better I like it, it is so much fun to use, I am sure that all you Tejon swingers can relate. .
