cz-3d nickel test.

I have a new cz-3d,curiousity killed the cat, soi had to try the nickle air test.got 8 of each v nickels buffalo and old and new jefferson. set the detector in pre-set 0 disc enhanced mode and in both modes all coins I.D in high tone nickel but one a 1883 v it fell to foil. Turn disc to 3 all cions still I.D high tone nickel in both modes. it would not I.D the 1883 v at all.The only other coin that would not I.D in high tone was Flying Eagle cents they went to square tab mid tone.BILL-N.C.
 
it also any gold ID'd in mid-tone as well, which was supposed to be thrown up into the hi-tone area as well. This was in the enhanced mode. I think what happens is, when they set the peramiters up in the machine some are different then others.
 
The 3D needs the ground matrix. Also if the nickle is super corroded and has a lot of the coin leached away by ground minerals might read lower. I can't even tell you how many old buffs, V's and shield's i have dug with the 3D. If you are not satisfied with the machine send it to Fisher to be checked out. The machine works just like it is advertised. The new junk nickles don't even read like nickle. They read pull tab on my MXT. I don't care about them any way. I am after the old deep stuff anyway where I am at. If you are not digging 10+"s you might as well go home. Go read NASA Tom's write up on the machine and read your manual. If it don't work that way then just send it to Fisher to be fixed cause there is something wrong with it plain and simple. The new nickles hit pull tab on my 3D and every once in a while it will hit high tone. also. I have found nickles from tinfoil to Zinc Penney's especially the war nickles with my other CZ's vice my 3D. War nickles read all over the place. Again it is due to mineralization and depth and composition of the metals of the nickles. My 3D works just like they say it is supposed to work. Some of you guys need to go to the Fisher web site and down load Nasa Toms little book he wrote and read it about 4 or 5 times to grasp all the important info he has there. What you have is two great detectors in one you just have to understand what it is telling you. If someone has a new red book maybe they will look up the combination of metals that the new nickles are made of. I don't have a new book so I don't know what they are made up of. Compare the new nickles to the old ones and lets see what there composition is (what metals they are made of) are. HH Jerry aka Tinfoil.
 
with the 3D. It ID'd as nickel in the ground, but after I dug it up, it changed ID's.. The 3D did just what it was designed to do. It found an old cruddy nickel (which seem to drop in conductivity over the years). Interestingly enough, you can re-bury that same old nickel, and it will still miss-ID it. However, when it's been in the dirt, undisturbed, for a long time the 3D will sniff it out.

are you saying it ID'd gold coins that were in an undisturbed ground matrix at a site that had activity no later than 1950? I ask because I, like many others I suppose, have never found a lost old gold coin anywhere. Fisher and T.D. has always been very consistant and clear that the conditions I mentioned were what the 3-D in enhanced mode was designed for. When I've used mine IN THOSE CONDITIONS, it's been scarey deep and "correct" with it's ID's. As you and most others know, if you want to use this detector for general detecting in modern sites, you have to be willing to use the salt mode as needed or as a "target check" if you want to trust the ID displayed.
 
CZ3D enhanced mode enhanced parameters gives one a better chance of finding one...as many read in oddball areas....
 
but if you only dig Hi-tones as suggested by the manual, you mostlikely won't find one. Because with my LIMITED experience with the CZ3d, the gold coins and the gold jewelry that I tested gave a mid-tone & either a foil or pulltab reading. I saw no difference in this with the CZ3d in enhanced mode then I did with my CZ5 in normal mode.

Every now and then you might get a hi-tone chirp, but mostly a mid-tone. Now the CZ3d was designed and intended to throw old coins & gold jewelry into the hi-tone area, no matter what the meter read, but this was not my experience with the machine.

Now, I'm not knocking or bashing the CZ3d, but the one I had didn't perform the way I saw Tom Dankoski's perform at the Daytona Beach Shootout a couple of years ago. I still feel that mine wasn't up to pare, but according to Fisher Lab's, it was working as supposed to. Go figure!
 
that it's such a departure from anything else out there because it apparently was designed at least in part, (when in the enhanced mode) to do things "differently" from other detectors. We all like to do tests a lot in the hopes of defining the capability of a detector and develop confidence in it prior to, or in between, actual field usage. I believe, for whatever it's worth, that the 3-D, when in enhanced mode, more than any other detector out there, will just mess with your mind when we do our tests, whether they be air, or in our test gardens. Most test gardens don't date back 50 years so can and should we really put much if any faith in what we see from them when using the 3-D? I'm not saying anyone here doesn't know what they're doing or that so and so's detector must be messed up and another is probably just fine. I am saying I think the 3-D in enhanced mode should not be evaluated by "testing". I fully realize that it's very difficult to find a site that is by definition THE place to capitalize on the supposed unique strengths of the 3-D, but I do know the several times I did use it at such a site, it worked VERY well, and found a shocking amount of old targets behind years of hunting with Explorers and everything before that, etc. The old coins consistantly did in fact register in the high tone and based on my experience, wouldn't have with any other detector that I'd used up to that point. Once again, I get the same sort of results everyone is talking about WITH MY "TESTS" on my 3-D, but in the true older intact fields, mine works as billed.

Did you ever send it back to Fisher or did they decide it was OK over the phone, and was this a new unit ????

Thanks

Everyone has their opinions on the 3d. All I know is it works just as it was said too. It works on nickles in the ground and that's where it counts. If it didn't go high tone and ID as a nickle it was something wrong with the machine or the operator didn't learn the machine. Just my nickles worth. Jim
 
The ground matrix and the coins have to be down there for quite a few years. I hunt old/new places that are so trashy you just would not believe it but, that is where the old stuff here is and it is deep. It is 8" to 12"s deep here. I usually use the 5" coil and seldom use the 8" coil. I don't have much mineralization here and my machines preform great or they are gone. When you use these types of places to hunt you just have to see what the target depth is and that is not in concrete to decide which mode to try to get the best idea what the target is. Flip the switch between salt and enhanced and see what you get. I got a life time warranty and I don't care if the switch wares out. I agree with the test garden and coins not being buried long, don't bother using the enhanced mode. I don't in my Garden as it is a waste of time and is not a old garden since I moved. The machine is not designed for that. You have to find out how old a place is first and decide which mode you are going to hunt in or are you going to use both modes and how deep the old coins are being dug at. Last but not least. If is a old/new place CHECK THE DEPTH AND FLIP THE SW. :D: :D: . Yeah, It drove me a little wacky :bouncy: at first but I done a lot of reading on the machine. I read all of what NASA Tom had to say about it. Done a search on the forums . In the Enhanced mode you are talking about a machine that is 180 from the CZ's. Hunts entirely different then they do. You have to learn how to hunt with it. If you are used to the CZ's that is a great help. If you are not then you have to learn to hunt with two different machines. Don't get discouraged. It is like learning two different machines at the same times if you have not used the CZ's before. I have dug more old coins with my 3D in the Enhanced mode then any detector I have ever owned and brother, I have had them all and still have 12 machines. My Sweetie uses her CZ6a and Sidewinder MM. She said one time, if I ever get rid of her CZ6a or Sidewinder I might as well go with them. :D: :D:. You guys just got to get in the dirt with the 3D and hunt with it and learn what it is telling you. Later and HH Jerry aka Tinfoil.
