Lot of questions about how to get the most out of your E-Trac. This is the forum to ask those questions and get very good answers. I myself have benifited from questions from me as well as others but have you noticed Ray Mo., Dr. Bob, Andy, and Bryce Brown don't ask questions but provide answers. Now that being said everyone knows my settings here in TN. will be of little use for Del in Oregon. So here is a suggestion that helped me tremendously. I took some golf tees and when I found a penny I put a golf tee there, same with nickle, dime, quarter and pull-tab. Don't dig first leave ground alone. Now check these targets with different settings gain, sensitivity, target tones, noise cancel and try different channels. Some have done a test like this and if you have'nt, try it. You will get some interesting results in YOUR ground. Try pitch and hold in a trashy park now that is an experience. Try new settings and before long you will be amazed at what this machine is capable of and the aggrivation it can cause.
