Fisher CZ-3D Metal Detector

If it's in the Ground or in the Water a Fisher Metal Detector will Find it!

cz3d combo The CZ-3D is Fisher's Top-of-the-Line metal detector using the latest "hottest" technology known as Multiple Frequency Detection. CZ-3D is an outstanding coin, ring and jewelry detector locating more targets deeper than many other comparable detectors. CZ-3D is also rated "Best" for relics and artifacts, especially those in the brass, bronze and copper categories. From all CZ-Series detectors it can easily double as a gold detector making the CZ-3D an EASY-TO-TUNE, EASY-TO-USE TOP OF THE LINE "All-Purpose" Metal Detector. THE CZ-3D CAN DO IT ALL!

The CZ-3D is Fisher's Newest Multi-Frequency metal detector that all other detectors will be measured against. Maximized with the NEW ENHANCED MODE, the CZ-3D is the ONLY metal detector designed to find VERY old and more valuable coins, rings, and artifacts. The CZ-3D does exactly what all coin and treasure hunters want... to find large amounts of coins and other treasures. At older sites and locations (even those that have been heavily hunted by other metal detectors) the CZ-3D with the NEW ENHANCED MODE finds more of the older, valuable coins where other detectors have passed them by.

Take the CZ-3D challenge today and find what you've been missing! CZ-3D features the new enhanced mode for the very best performance when hunting older sites, It's that simple! The CZ-3D looks like, and nearly sounds and operates like, a standard CZ but delivers exceptional performance on older more valuable coins. Specifically designed to find more good metals such as silver and gold (coins) as well as coins made from copper, copper and silver, and brass. The CZ-3D accomplishes this by using the new ENHANCED MODE which reports theses hard to find coins as a high-tone (good), rather than a mid-tone (bad) object which would NOT be dug by a detector user. The CZ-3D is engineered to provide maximum success on old coins while retaining the best possible ratio of good targets vs. trash targets. In older sites, where aluminum trash is minimum, the CZ-3D will give exceptional performance on older coins. Simply select the "Enhanced" mode switch. No special or lengthy programming required, just flip the switch and see what you've been missing.

During the CZ-3D Field Test, Tom Dankowski's detecting buddy Porter found an 1885 "V" Nickel that read "hi-tone" (good) on the CZ-3D but read "mid-tone" (junk) on other detectors tested. P.S. Value of 1885 "V" Nickel is from $300 to $900

The CZ-3D is designed to better distinguishing old coins from Trash Objects

CZ-3D more easily finds older coins such as nickels, Indian head pennies, gold coins, older silver coins, etc. CZ-3D pulls these older coins out of the Pull-tab audio range where they are normally located due to older coins having a longer different matrix rate of decay. Without the CZ-3D ENHANCED MODE, these older coins would sound the same as a pull-tab. With the ENHANCED MODE, Pull-tabs are kept in pull-tab range. YOU CAN NOW TELL THE DIFFERENCE BETWEEN AN OLDER MORE VALUABLE COIN AND A PULL-TAB!

cz3d enhanced Another new feature of the CZ-3D. As expected, a mid-tone sound is heard on the "foil, round pull-tab, and square pull-tab" icons. However, the audio reporting system has been ENHANCED so as to present a slightly lower audio tone on the "foil" icon ONLY. The "foil" audio is still a mid-tone, but comparatively sounds a little lower in pitch. In certain detectable areas, there can be tremendous benefits by distinguishing between "tabs" and "foil" with the audio target ID.

Unique Instructions

CZ-3D Primary Purpose = Enhancing the Detection of Specifically Old Coins

cz3d front After 2 years of extensive programming, calibrating and field-testing, (my apologies for being exceptionally slow... but thorough), the CZ-3D is now maximized for a very specific function - finding older era coins at older sites. To ascertain this extensive programming, simply select the ‘enhanced’ mode with the utilization of the ‘salt/enhance’ switch. No special or lengthy programming required on your part. And for the first time, this CZ has been engineered for “General Purpose” detecting AND “Specific Purpose” detecting (that being specifically the older era coins). The CZ-3D does not require a new ‘learning curve’ per se - it is the age of the areas that you hunt that will present a new ‘learning curve’, while in the ‘enhanced’ mode. The dirt you select & detect will be your learning curve.

If you are new to the CZ series of deep searching metal detectors, place the ‘Salt/Enhanced’ switch in the ‘Salt’ mode and follow all of the standard operating instructions provided. For advanced hunting, and for those who are seasoned CZ operators, follow the unique operating instructions provided below.

Congratulations on the purchase of your new CZ-3D! You are in for a bit of an ‘eye-opener’. With the new CZ-3D placed in the ‘ENHANCED’ mode, here are your operating instructions:

  1. Select your oldest detectable areas
  2. Sweep coil
  3. Find ‘high-tones’
  4. Dig

front button It is that simple. The CZ-3D looks like and nearly sounds & operates like a standard CZ. The largest attribute of any CZ are the tones - and since we detect nearly exclusively by the audio tones, this is also where the CZ-3D accelerates. Just a few simplistic audio tones keeps this unit free from “mental fatigue”. You will not notice any physical or dimensional differences from a standard CZ, however, your luck will ‘appear’ to be greater with the CZ-3D, by no accident.

Wish There Were More Coil Options

Review by Big Sky on March 15, 2019

As far as the machine itself, I'd give it 5 stars. It does what a detector is supposed to do, without being overly complicated to learn. I got the CZ-3D to compliment my Fisher 1270, which I also bought from Kellyco. The 1270 pretty much sold me on Fisher products. I Upgraded the CZ-3D with the 10.5" coil. It picks out the deeper stuff really well, but bigger and deeper isn't always better and there are times when I want better target separation. I just wish there were more coil options to choose from.

Well let me say if you want depth the Fisher CZ-3D is the machine. Over the years past 29 years, I have tried most of the top of the line machines. I must say that the Fisher CZ-3D - with its stock 8 inch coil - picks up deeper objects than any of the the other machines I have used. I can go back to my old places that have been hunted hard in the past, and still pull out the good finds that my other detectors missed. This Fisher CZ-3D is like a pulse hybrid, as I have dug coins, rings, and Civil War relics at depths that I have never seen before. I will say that this is one awesome machine. Awesome depth, great discrimination, and I love the tones. If you are looking for more depth, this is your answer.

Review by Clay on July 11, 2012

If you are a newbie, please don't leave a crappy review on here based on your lack of experience. It's neither helpful or fair to judge a specialized machine that does the job it's intended for very well. The CZ-3D is a specialized detector, and it does have a bit of a learning curve to it. But what it boils down to is, if you are a dig everything kinda detectorist then this might not be the detector for you. If you like to go for the silver and not dig up a thousand pennies and pull tabs, this is the detector for you. I've personally hit silver dimes as far down as 10-12 inches in mixed rocky soil with my CZ-3D. The problems that some people are having with this detector are easily overcome with a little practice and by following a few tips.

First, study the manual ground balance procedure in the manual and practice it until you can do it. This will give you the best depth and more accurate target identification. The Salt / Enhanced switch isn't just for the beach, if you are having problems getting the machine to balance in heavily mineralized soil turn the switch to Enhanced and you will have better results. The 4 tone ID makes searching very fast and all high tones are going to be good targets. Most nickels will hit as a high tone as well which makes the CZ-3Da nickel killer.

Gold hits in the mid tones. Take a minute to throw down a gold ring and note how it registers as a hit on the detector. Gold, as opposed to pull tabs will register as a very strong tone and if you lift the coil 4-6 inches above the ground you will still get a very strong signal. The CZ-3D will give a positive high tone on large iron objects. Just hit the pinpoint and check the size of the target. If it's a small blip that hits from all directions it's a good target. If you get an erratic or strong tone in a larger area it's most likely a pipe or large metal object.

I would certainly recommend this to anyone. Good Luck and good hunting!

Review by J-mann 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.

Aspects which pleased me: I was impressed with the easy to use presets on this detector. There was no need to balance the detector or know the advanced technique before being able to make basic finds using the presents. The salt mode also was helpful for beach hunts. Moreover, this detector has great depth and was able to pick up some old civil war musket balls in mineralized soil at a depth of almost 12 inches.

Negative aspects: There are unit hardware problems. In two years, I have had two problems with the quality of the CZ-3D. First of all, when I received it, the knob had popped off the discrimination fob and I had to wait for almost a month to receive a new knob from Fisher (Kellyco was great) which I had to install myself. Soon, however, this new knob also fell off and got lost, which says something is wrong with the knob itself. I still cannot adjust the discrimination. Secondly, now, at two years of age, the unit is not producing sound and is currently being sent back to Fisher for servicing. This is frustrating because my summer is being wasted while the unit is being serviced and also because the expense merely to examine the unit ($50) is not insubstantial despite the fact that the unit has a "five year warranty."

In terms of performance, this detector seems to pick up some large rusty metal targets even with the discrimination set to high and the sensitivity down.

This being my first unit, I am not in a position to compare it with others. It has given me some good finds but I've also been frustrated with it. Overall, I'd give it three stars.
