Dis., don't matter in this case. I push the pinpoint button on a target that reads 15, 12, on depth, which is target down 10"+ the threshold audio in pinpoint is so loud that it interferes with the pinpointing of the target. Now on a shallow target 5 and 6"s it detunes and the threshold audio will quieten down. At first it is loud but you can detune the target but not the real deep one. Go to All metal and everything works fine. This is with the new 5.75" coil and the 8" coil, both coils do it. Do your ID Edge's do that or is it just with mine. Also does your pinpoint button have a small delay between pushes. If I push it a couple of times trying to detune the target it just reverts to regular target mode not pinpoint even with the pinpoint button pushed. If I wait a 2 sec count it pinpoints OK but with the same results as before on deep targets. Just used to my CZ Fishers I guess. If I remember right my ID Excell did the same thing with the too quick of a push on the pinpoint button. I don't remember it doing the loud Threshold audio thing on a real deep target though. Anyway just something I need to find out. . HH Jerry aka Tinfoil
