I have had my etrac out a dozen times and getting pretty used to it's sounds, numbers and I must say it's rather addicting too . I already have about a coffee cup full of clad, a few silver jewelry pieces............but haven't picked a single nickel yet I am using the factory settings as of now. Love the machine and can't wait to get into some better sites to hunt. If it is the settings masking andit means not many pull tabs, then I guess it is worth the trade off. Am I missing something(besides nickels)?
