Some of you may have read my field test of the new F2. In there I said that it classified tabs as coins if they were 2 inches or deeper. Other than that the detector worked great. Well Andy,NM of fisherf75.com contacted me and thought my detector needed an adjustment. He said he talked to Fisher and they said my numbers were out of normal range. He suggested I send it in. So that's what I did. From the time I put it in the mail it only took 6 days to get it back to me. I have to say that the target ID and numbers are spot on! This thing is a real nice detector. With 2 coils and an extra lower shaft for $199.00 it's great! Many thanks to Andy, NM and Fisher!
