Ok, first post. I'm am a newbie and have been reading a lot about different detectors. I was kind of set on an Ace 250/350 then started looking at used mid range detectors. Just when I think I have decided on a used Whites XLT the DFX starts looking good. Then an X-Terra 705, then an AT PRO.....etc. etc. I live in Civil War country so fields, woods and maybe even shallow water would all be on my list. I don't want to start at the bottom and not be happy with my purchase. I would like to keep it under $600 or so. Any suggestions or advise would be greatly appreciated. Please help me make up my mind!
