? I went with my Dad once.. if he actually read the manual I would have been surprised!!! I dug a nice little Union eagle button while he dug a US plate and two VA one piece buttons... feet from me!!!! Great machine.. plently of reading up on it.. research. all of that... still boils down to it has to be your coil passing over the object over everything else... soo.. keep swinging!!! The ironic thing is.. the day my Dad did so well.. his knee was bothering him so bad.. I dug the US plate for him!!!! Talk about humbling.. "Yah, got another beer can... what you get... "oh, another VA btton!!! ;-)
