I generally will MD with my sensitivity pretty high (provided the mineralization isn't too high) and discard only nails. Here's my issue. When I hit the tot lots that have metal playground equipment, I can't come any closer than about 14 to 16 inches from any "pole" without getting a false signal. The Prizm V will tell me that I have a good nickel / ring target at about 2 to 4 inches every time I get that close to a "pole" on the slide, swing, whatever it is. Also, it only does this when the coil is exactly perpendicular to the "pole." It doesn't matter if it is to the side, in front of, or behind the coil. I will get the false signal every time. I feel like I'm missing a lot of potential targets close to and under some of this playground equipment because of this. Anybody out there run into a similar issue? Any thoughts on a solution would be helpful.
