I have found that tiny things such as very, very small pieces of can slaw, have to be almost touching also. I could be missing out on a stud earring here and there. On average, I have only counted on 1.5 inches for the Pro in the past, but this new one stretches out a bit further. Three inches would be a reliable stretch though, yet I do get chirps near 3 in air, at least on a dime. I think I've found my answer. The older Pro Pointer diminished a little over time of use, but still makes a find backup. I can't imagine a different hand held PP keeping up with either of the two. Maybe the Pistol, but not overall. martin
