Well I know there are a lot of people knew to the machine who get on here looking for direction, and I know there have been a lot of posts about different settings to maximize the abilities of the machine, so I just thought I would share what I use and what has worked well for me. First of all the standard advice is right, stick to factory presets with conductive tones until you really get comfortable with the machine, then you can start to dance around with it a little. A good indicator of when you are ready to move on to other settings is if you are really starting to enjoy the machine, you know you can find good stuff with it, and your anxiety about using it is gone. Once you reach that point the first thing I would try out is switching over to iron mask at preset levels. It is convenient that while you are getting comfortable with this you can toggle back and forth between iron mask and factory presets just by hitting the iron mask button. If pulling silver is your thing there is no doubt you can pull a ton of it in factory presets and I often still do, in fact if I am feeling particularly lazy and only interested in cherry picking silver I will even go beyond that and add more discrimination to tune out other unwanteds such as pull tabs. Trust me the machine still works great that way and I have a cigar box full of silver to prove it. Now, if you are really really comfortable with the machine, and wanting to get the most out of it (be one of those explorer vultures that goes around pounded parks behind other guys pulling those deep hidden signals) there is in my opinion only one way to go and that is to hunt with the screen opened wide up and sounds set to ferrous. The reason for opening the screen wide up is that will help the machine process and recover a little quicker and help you find those tough targets that remain hidden to other machines. The reason for the ferrous sounds is that with the screen opened wide up in conductive sounds nails and silver sound exactly the same and I for one want to make certain that the silver signals absolutely jump out at me so that there is no chance of my missing them because I wasnt paying attention or looking at my screen. With the machine set to ferrous sounds now your nails are a low tone, but silver keeps that same beautiful high warble pied piper flutey sound. While I respect the opinions and input of others, and I am more than willing to try anything new, I personally have not found the value in using the "2 tone" set up with the explorer as it only limits the input you receive from the machine and will not increase its performance. In fact that set up is really designed to correct what many see as a short fall in the E-Tracs and bring them on a level with the Explorers. I have found most of the other setting options inconsequential with negligible impact on performance if any at all with the exception or certain rare situations that require tailored tweaks. I think that set up is a must if you are relic hunting or in a non trashy area, or if you really wanna find those sneaky ones in the pounded out parks, but like I said before, its tough to use and its going to be an absolute information overload if you are not already extremely comfortable with the machine. On a side note my degree is in archeology and while I did not pursue it as my profession it is sort of a part time business of mine. As a result I often find myself in situations where I am running my explorer over gridded out areas of a historic sight that have already had every inch of ground covered by other guys with other machines. I can tell you based on the number of items I pull coming in right behind those guys that the Minelab is really a cut above the rest, and the archeological community knows it as well as they always want me to come in behind the other folks and see what I can pull out before they will call the dig done. The settings I have given are just my opinion on how to get the most from an already awesome machine. I hope they will work for you as well as they have worked for me. I hope this post is helpful for folks looking for ways to get the most out of their gear and I invite everyones feedback be it positive or negative. Feel free to post any other settings you folks have found to work as well along with your thoughts on them. Thanks for reading, and happy hunting, Bell
