My, My, My, such problems, too many brands and models to choose from to settle down and get to know one real good before trading it off for a supposedly better one. I have metal detected for close to 40 yrs. and have observed the increase in new brands and models, and great claims of each brand claiming to be the best, the deepest, the easiest, the most accurate, the lightest, the best balanced, the prettiest, the cheapest, the oldest, etc. and I have read a lot of forums and I have used most of the major name brands and I have decided that most all of them are good capable detectors, each has a few little differences in features, but basically all are comparable so close to each other, the differences in performance is minimal. If a person is interested in only going out and finding coins or relics and don't care if the machine gives him a plethora of information or not, then one of the turn on and go detectors with auto ground balance and just knobs for sensitivity, and disc. and maybe freq. change is all you need. Forget the meters, belltones, tone id, VDI numbers, icons , 99 freq. those are just extras that are not really required for finding targets. Buy a good reputable detector,( I don;t care which brand ) and keep it long enough to learn it thoroughly and you will have success in your hunting. I don't believe " the best of the best" has been made yet. But there are some good ones out there that sure is an improvement over what I started with. I use a XLT Spectrum and have had it for 3 years and am very satisfied with its performance, and I still don't know all there is to know about this machine, I'm still just using the factory coin and factory coin/jewelry programs, I have experimented with some custom programs, but usually return to the factory settings which work very good. I'm not in a depth contest when detecting, I don't like to dig over 8 to 10 inches for a possible coin, not in this Missouri rocky ground here where I live. Just to mention my wife hunts also and on our excursions, she will find as much as I do in face value of the coins found, and she uses a Whites Classic II, I offered to get her a upgrade to a IDX or ID that has the target ID on them but she said "no" she is satisfied with the one she learned on and it does alright for her, which it does.
I hope you like the XLT, You didn't mention the 4 other kinds of detectors you had tried so I can give you no comparison there. The only important thing is, if you like it, your the one paying for it, and its your time and energy your using when out there hunting, and there hasn't been a detector made that can make no mistakes, it still comes down to the discriminator in your hand, namely your digging tool, and your thinking cap.
