Hi folks, I am getting a new to me Fisher CZ-5 this comming Friday. I traded a Tesoro Tejon for it, the guy I am getting it from said that it was sent in to East Teaxas Detectors and a person named Keith Wills recalibrated it (whatever that means). I found a few tips on the CZ-5 and read through all the posts on this forum that I could find on it. I like to hunt school grounds,parks,ball fields & tot lots, my question is - can I expect to find jewelry with it like I did with my Tesoro's, especially in the tot lots. I just love finding jewelry even if it isn't worth anything. Thanks all. Steve.
