Been away from the hobby for the past 15 years and decided that I wanted to get me another machine so I bought a used F70 yesterday. My last detector was a CZ7a and it was a great machine so I assume that the new detectors that are out now must be much more advanced than they were 15 years ago. Can't wait to get it out in the field and try it out. Hopefully it will turn out to be a good purchase. Be good to be back in the hobby again. Cheers!
