Hi folks. I am glad to find a forum dedicated to Fisher users. I am 58, recently retired and returned to metal detecting after a twenty year absence. I live in Northeastern Oklahoma. After an unsatisfactory experience with a cheaper detector, I purchased a new CZ-3D about a month ago. Oldest coin to date is an extremely corroded 1900 Liberty V nickel. I reall like the quality of my CZ-3D, but I am still having some long learning curves. My biggest problem is pinpointing. If I am in a discrimination mode and I get a good signal in a trashy area and push the pinpointer button, often the detector will pinpoint on a nearby ferrous object and ignore the good target I am trying to get. This appears to be because when the pinpointer is pushed the detector goes into all metal mode and hones in on the strongest signal within the search coils range. You can "tune" the pinpointer by engaging it closer to the target, but if the trash is nearby even this doesn't usually work. Deep and weak signals often will not pinpoint al all. I have ordered a Fisher five inch coil that I hope will improve my pinpointing in the trashy areas I hunt by narrowing the field of the coil and I am trying to get better at not using the pinpointer at all. I also dig lots and lots of rusty nails that sound like good repeatable signals. Why doesn't the discrimination work on these? Any suggestions?
