im leaning towards purchasing either the Minelab GP 3500 or the Minelab Explorer 2. I want to use the detector for locating gold as well as relics and coins etc.. I understand these are some of the top metal detectors on the market. I also want one that goes deep into the ground. Is the GP 3500 better for finding gold than the Explorer 2 and wich detector is better for finding relics and also which one will go deeper in the groung? If there is someone that has experience with either one can you please give me your opinion on the overall best one so that I know what im dealing with hear before I purchase one. Thank you very much.
