now that I am starting to get used to my new etrac , I am going back to old sites that I Hammered to death years ago with my Garret grandmaster , with 4 different coils .At that time 20-30 years ago I found lots of coins . I stopped going , when I could not find anymore . Also told members of my detecting club to go there and see what they could find . No one could find anything . UPDATE - I just went there again 25 years later with new etrac ,and Im finding coins again , mostly 5,and 10 cent silver that the Garret would not detect . Its nice - no research just visit old sites wow . - mike
