Kyle, skypilot02 here. Other than being sure your unit is properly ground balanced, the only quirk that comes to mind is if you have a signal that reads well one way but pops the other way, then you probably have deep iron... Although, that is not always the case! Sometimes a coin on edge will do this, the way I try to tell the difference, is to raise my coil higher than a coin would produce a "good" sound, if the target disappears, then it could be a coin, if not, probably a nail, or other iron trash. Listen very closely and you can hear what I can only describe as a whine at the end of some signals, and this seems to indicate a nail in conjunction with the above noted conditions. Also, there are times when you notch out iron on the Pro, and the unit seems to lump portions of this into the coin icon. I don't know why, but it happens here in East TN. Best advise is to practice over and over! Find a place where you can feasibly dig say, the first 15-20 targets you encounter, and pay close attention to the sound, maybe write down what the detector reading is, and then you may have an idea about how your machine operates. I would suggest doing this with no metal notched out, and dig every signal you come across, until you feel confident in what the SOUND as well as the icons are telling you!! I love my machine, but, like any other manufactured product, each one has a different "feel" to it. Get to know yours well, NEVER give up, and look for treasure where folks are, or were, and I'm sure you'll have great success

If you have any particular questions, feel free to ask, that is how most of us learned! Great hunting and good luck!! Regards, Richard
