Fisher CZ-3D Metal Detector
- Product Review (submitted on March 16, 2010):
I've been detecting since 1968 (BFO-type machine). I've used just about every brand machine out there and many -- if not most -- were good to excellent. However, I've now settled into a profitable comfort zone with my Fisher CZ-3D. For a newbie, this machine has all the median settings, i.e. factory settings, well marked. Just align the knobs with the highlighted orange settings and you're instantly in the swing of things. This detector has very good sensitivity on the factory settings -- and odds are good that a reading, however slight, is something well worth the dig.
Sidebar: Hey, even finding a used shotgun shell has a beneficial purpose in the way they indicate a detectorist is hearing readings properly and in a range that could easily lead to the likes of a half cent. It's always good to learn a machine through less-than-golden readings.
The sound ID is so good on the CZ-3D that even a beginner can quickly feel comfortable moving away from the factory DISC (riminate) setting "3" meant to find coins. I prefer the 1. Yes, that allows iron to be heard. However, iron readings come through the headphones as a distinct sound, easily differentiated from nonferrous metals. Nonferrous metals have their own distinct sound signatures, depending on the type material. Sidebar: The top treasure hunters feel it is often vital to run with a setting that reads iron, especially when exploring open stretches of woods or fields. Iron is almost always a sign of past activity and areas where prime items might then be found. Once into the iron zone, a quick switch back to a factory set 4 makes the search a breeze.
From a more professional angle, the CZ-3D is as good as it comes when the SENS(itivity) is cranked up beyond the orange FS 3. I go as high as 7 or even 8, depending on the degree of microwave or electric chatter in a given area. This move is not for newbies. It entails learning to listen through false signals. It then comes down to ferreting out repeatable readings.
