The last 6 months I have spent using 2 other new detectors only to return to the CZ 70. I have been using CZ s since 1993. I have updated it with some Garrett wireless headphones!! I love the comfort I have with it. Great Audio, modulation, deep, pinpoints precise !! I wish Fisher would come out with a new CZ ..... ultra light version would be great !!! As newer detectors are released, I still will purchase and try to replicate the performance I get with the CZ , but as of now Cz is still the top dog in my arsenal !!! HH Tony
