: Hi, had a quick question on the pinpointing. When I go to pinpointing a possible target, I keep the searchcoil approx. 1 to 1/12 inches off the ground as I move the coil over the area but when I raise it anything above that (from that position to say 2ft off the ground) it will sound off like it would if it had pinpointed the target(steady hum). Just wondering if this is normal? Also have the 10 x 14 DD coil that I have not yet used and was wondering if this would work better? The area that I hunt is in northern Illinois which to my understanding is not too mineralized. Thanks for your time, Dave
