Hi everyone. I'm writing to find out which brand and type of metal detector would be most suitable for me. I have always rented metal detectors in the past, and have had some success with them. I just recently rented a Whites Prizm 2 about a month ago, and went looking around up on a farm my uncle owns in Wisconsin. He has alot of large open plowed fields, but I was only there for 2 days so I stayed by 2 old homes he has on his land. I found mostly old jar lids, and rusty nails, but this I believe was mainly because of my experience with metal detectors (I'm still an amateur with them). But I did eventually get the hang of using it on my 2nd. day up there and I found an old "tootsie toy" truck, and a 1987 quarter, so in all it was'nt too shabby for me. But needless to say this really "hooked me" to the hobby. So I have decided that I would like to purchase a higher-end detector at this time. This is not because of any problems I had with the Whites Prizm 2. The Prizm 2 was a nice easy to use unit. I guess after all the reading I've done, and all the things I've heard from people and forums and all kinds of dealers, I feel I'd like to move up to a more sophisticated detector. I would really like to purchase a good "all-around" detector, with good depth. I have read alot on the forums that depth really isn't the most important thing. But I guess after reading stories about how other deeper seeking detectors have found things that other detectors hav'nt, this kinda' got me thinking in this way about depth. I will mainly be using the detector in large open plowed fields, like the ones my uncle owns in Wisconsin. So I'm assuming I will run in to highly mineralized soil there. So I would like to find a detector that automatically adjusts itself to the present soil conditions. I've narrowed my choices down to either the Garrett GTI 2500, the Whites MXT, or the Minelab quattro. I have heard "alot" of differeing views on all of these machines. I know the Minelab Quattro using multiple frequencies ranging from 1.5 all the way up to 100 khz. I was told that this offers a wider range of targets to seek "simultaneously" from small to large at "way deep" levels. But on the other hand, I've also been told that the multiple frequency "hype", (as I was told it was), is...and I quote this from the detectorist i spoke with..."a bunch of bunk!" So as you can guess I'm pretty lost in the whole thing. I know the models I mentioned have a large learnng curve to them, but I'm in this for the long haul. So I'm not scared off by that so much. I really just want that good "all-around" detector that will do well in, most likely, highly mineralized grounds, that adjusts to this automatically, with the ability to hunt old home sites every now and then. Thank's for any advice or info. anyone can send. Randy
