I had the 8000 for................
a while. It was a good detector for sure. But, me being me, I decided to trade it off and try another detector. I am known for trading detectors. I have traded quite a few looking for the detector of all detectors. I think it is time I stop! I can say that the best detector in the universe is worthless if the operator doesn't know how to use it. The best detector is the one you know how to use the best. Once you have become one with the detector and know what it is telling you, then there is no reason to shop around any more. Good luck with the 8500. It is a darn good detector.
