Not knocking Fisher at all, was very sad when Fisher HAD to sell because they lost law suit. It was all because of Fisher's New CZ20 water machine a few years back that used several frequencies. When it was found out how they achieved their results. Now don't quote me here.... Minelab sued them for using their technology and patent for multi-frequencies. Fisher lost to the tune of 7.5 million, Fisher (in order to pay) had to sell out because they didn't have enough cash in the bank. I was sorry to see this happen. Fisher immediately called in all unsold CZ20's (water machines) and they were replaced with CZ21's which are NOT as hot on gold as the CZ20's were. Now, if you were lucky enough to get your hands on a CZ20 and you had to send it in for repairs, you recieved a newer CZ21 in return. I know this only because our club had one involved in a progressive raffle that ended in Nov. of that year. Fisher could not get that one back because it was purchased by our club before the law suit. So what it all boils down to is, If you were lucky enough to get your hands on a Fisher CZ20 water machine, hang on to it, try to have it fixed by anyone but the factory, or you'll get to be the proud owner of a new CZ21! BTW.... I have owned Fisher Metal Detectors for many years including ~ Aquanaut 1280-X, 1260-X, 1265-X, and still have my original 1266-X, now that is one heck of a relic machine and will never part with it. I own 3 machines right now....Minelab Explorer XS -II, Minelab E-trac, and the aforementioned FISHER 1266-X!..............NGE
