Paul, I can understand you being concerned about the Quatro considering all the different posts there are on it. I know there's everything from "boy this is great" to "gee, I wonder if it's OK", but as far as I'm concerned, and I own one, it's by far the best detectro I've ever owned and I've had a few other ones. I used to have a Garrett Master Hunter 7 and an old bounty hunter plus, before I traded it in on the Quatro, I bought a Minelab Muskateer. I liked the Musketeer for the price but seemed to have trouble with it near the salt water and black sand. I never could get it to keep from falsing, and the only "guess" on that one is it only has one frequency. I don't think you can lose with multiple frequencies, especially with Minelab. I very seldom have any problems with it at the beach or anywhere else except possibley near huge power lines, but I used the ground cancel and it helped a lot. Very few problems with those things and I can tell you, you don't want that problem. It can ruin a good time if you have to constantly deal with false signals at the beach or anywhere else. When I first got the Quatro, I had some problems trying to sort out all the different tones and chirps and stuff. For a bout a week, I had trouble telling what's what, but it ended up just being the learning curve for me and after about 2 weeks, I felt comfortable with it and it all seems to make sense now. Sure, now and then your gonna have a weird signal or something, but it seems to give very good and accurate information for me and I consider myself pretty critical in that area. I know it's not a perfect world yet, and if you don't believe me just ask Mike from Virginia beach how many differnt numbers gold can come up with, but for the most part, it nails down most of the coins and gives you great depth and good information with almost zilch on the mineralization problems. I'd say 99% of the time I can hunt at the beach in 4" deep salt water with black sand and there's no problem. I guarantee you I havn't had much nulling except when it's set to discriminate a particular metal, which is what it's supposed to do. The only guys I'm hearin crying the blues on that stuff is in Extremely bad ground with tons of iron. I've doug pennys at 1 foot deep, and if that ain't deep, I'd like to see what is. Let us know how it works out for you either way. I, for one, am always interested in what other guys are feeling about a particular unit, especially the Quatro. Remember too that it has notichable discrimintation you can set any way you want. You can also set the audio to ferrous or conductive through cross saving.
