There`s an old carnival ground that I have hunted for years and found more silver there than any one place I`ve ever hunted. I haven`t found any silver there in a long time. I purchased a 705 and a digger coil and did pull out four Wheaties and one nickel in a couple a trips. I have recently got an e-trac and want to go back to the field and hunt but have been trying to learn it a while before I go there because I don`t want to take it out and not find anything. I`ve been using just the factory coin mode and finding coins and jewelry, but nothing deep yet. Any suggestions on what to do with my limited knowledge of the e-trac. I`ve looked at the two tone ferrous set up and wondered if that`s what I should try. Thanks!
