Only thing I might disagree on is in PP/Am, I have found the swing speed of slow does not bring out the deeps as well. Their is a too fast but then med, too slow, is not the best way. Try it, and this is with the smaller coils like the 1000 n 800..bigger coils I am not sure. Find a deep faint target and test your sweep speed. It's like a small speed bump......the faster you go over that speed bump the harder it hits (ramp up then ramp down), the slower you go the less it is going to stand out. It's all about coil control, not to fast, but not to slow. That's the beauty of the remote PP toggle, you know "all" of the targets under the coil if your hunting in PP/AM, overly trash areas turn down the sensitivity and you can single out targets by a flip of the switch. You get a quick Beep beep, in PP, wiggle wiggle over the one target in PP then a quick toggle to disc the machine does not have time to see the other target and it will give you a discriminate reading. Then to the next target a few inch's away, do the same. It's does take a little longer but your not missing anything. If you were hunting in discriminate and one of the targets was a good and the other was bad you might only get a chirp, or a null and you would keep on going possibly missing treasure. Now in Discriminate mode, slow is good that way you can hear the chirps of the good targets when near nonferrous targets.
