I have been looking for a good used AT Gold to compliment my Etrac as a waterproof detector.....this isn't my first rodeo...with that being said, I went into a Pawn Shop /Garrett /prospecting dealer today and inquired if they had a used Gold, he said he only had a couple of new ones and then he proceeded to tell me how he took a small gold nugget, buried it 18 inches, and then buried a piece of sheet metal over the top of the nugget and it hit the nugget every time. I should have took him to task but I just shook my head and left. I feel sorry for the Newb that comes walking through the door with his hard earned $799.00 and believes what the salesman says as gospel...so to all the people who are looking into getting into this hobby, do your research, even your local dealer may try and take advantage of you.
