I do not Tim although I know many others do,for me it is a matter of what I am used to I learned the Explorer using conducitivity and I am more comfortable with it. I usually run -10 to -13 depending on conditions. Other clues are how the target pinpoints iron will often ping one place but pinpoint somewhere else, just be carefull here because if there are two targets in the ground they will sometimes both show up in pinpoint. If in doubt turn over the plug and if you have the X-1 probe it will usually tell you what is giong on.
Just this afternoon I was trying something I read about on the forum. I went to a old but very trashy park. Put on the 8" coil and went very very slow. Within a couple of minutes I had a high pitched hit but very iffy. Only hit in one direction, changed tones and the curser was all over the place but, and this is the best advice I can give you, in one direction it repeated and most important it just sounded right. With the Explorer trust the sound above all else! It pinpointed ok except there were two pinpoints one where I thought it should be, and another at about 2 oclock from where I thought the target should be. I turned a big enough flap to cover both pinpointed targets and the X-1 nulled when I checked the hole. That is usually a good sign the target was a iron false but that upper right target produced a slight high on and off tinkle. I took more off above it and out fell a 1903 worn barber dime. It wasn't 4" deep but had been missed before by other hunters because of the iron in the center of the hole and the near by trash. I rembember very well the confusion you are experiencing but stay with it, concentrate on those sounds and how it pinpoints and how deep it appears to be. The explore is a super machine and has added alot to the hobby for me because the more you use it the more you learn what it is capable of and I find myself going back to places I have already hunted and making good finds as this machine makes me beter. Best of Luck Rick
