I never thought that I would be without a fisher CZ of some kind. The E-trac has done great. Every time out I have found silver and or indian heads. I went to places that I was familiar with and have hunted very hard over the years. I have found barber dimes and 1887 indian head being the oldest coin so far. Also just received Andy's book yesterday and will read it. I have the E-trac and a Whites XL pro, which I probably should sell the xl pro as I can't imagine when I will use it. Even though it is a GREAT detector. I have never owned an Explorer as always heard about the difficult learning curve. I think the E- trac is fairly simple, even though I have much to learn. The other day I found 6 silver dimes and 18 wheat pennies. Have not done that well in one day since don't know when...For some of the negative reports I do not understand??? HH
