I'm new to the Etrac. Two weeks. Ive done fairly well with 8 silver and various old coins. I hunt very trashy areas. I hunt with sound and confirm with ID. Settings for me that have worked best are: manual sensitivity as high as i can without chatter, deep off, fast on, high trash, multi tone, CO, and normal response. My question is: I have tried long and smooth response because I have read that it works great, but when I try it, it seems that the signals blend together. Again, I generally hunt trashy areas. Is this something normal or do I need to change some other setting so i can differentiate between hits? As i have said I'm doing better with the Etrac than i have with any other machine that I have used in over 40 years of detecting but if I can get even a little better performance then of course that's what I want. I'm looking for some of you Etrac veterans to give me some tips. Thanks!
