My yard is a veritable graveyard for nails. For instance, recently I thought I found a repeatable good tone in the midst of all of it but after digging 6-7 nails and such out of a 6" sq. area, the tone was gone. Most places I go in the yard I just hear iron silence, no matter how slow I go. I'd try a concentric coil if I had one--I only have an 8" BBS--but since I don't, I'm at a bit of a loss as to what to do w/o turning the yard into a moonscape. I've tried auto, I've tried extremely low sensitivity, I've tried going very slow but I'm not having much luck. What would you do?
[Note that I seem to have problems with iron in general (I get awful tired of hearing that 180 tone on the edges of iron in a lot of the areas I detect. I can recognize the unidirectional aspect of the sounds, the moving location in all-metal, lack of repeatability from different directions, etc., but it still tends to drive me a bit batty in areas where about all I seem to get is the iron tone. (Doesn't help that at times you can x from different directions and get a repeatable good tone, only to find the edge of the coil happens to be going over the iron object.) Then there's the concern of missing good objects near iron.]
