I have had my CZ3D [new] since december but have only used it for a total of 20-25 hours so far.My problems are when pinpointing about half the time the pinpointing function just disappears and the machine defaults back to operating mode I have to keep pushing the pinpoint button to get it to pinpoint. Second problem is after pinpointing a coin and digging it up when running a handful of the dirt in front of the coil if it contains the coin occasionally the machine will not pick it up [I am not wearing any rings]? Third the discrimination seems to be crap,this thing loves iron even on the highest discrimination. I had my brother check some of my holes with his Compass that registered cu penny on my 3D [on highest discrimination]that I could never find but kept getting a good signal from x'ing directions and his machine indicated iron? I assume it was a deep iron object then-never found them after digging a foot down.Any help or ideas would be appreciated.the machine ground balances fine.I am not new to detecting been doing it for 20+ years just never with a CZ.The only thing that kept me from wrapping it around a tree today is I would not be able to sell it :] These problems occur in both salt and enhanced mode. I am quickly losing confidence in this machine.Thanx again in advance for any pointers or help you can send my way.

I'm not the best in my answers but...are you continuing to hold the pinpoint button in? If you release it, it does go back to operating mode. If it fades back to operating mode while pushing the button in and holding it there, then I think your unit may be faulty.
And yes, the CZs love iron and will sometimes read as high coin on deep large iron or nails. It takes a little practice to help that out...some good pointers are found on this very forum that may help you.
You have a lot of experience (20+ years)...but is there much with the CZ3D? CZs are fine units and built to last...but like all things there can be some glitches in a unit. Don't wrap her around a tree...she just may be a little sick. Hope this helps.

So not having a CZ3D I still own a CZ-70 pro. This is the best one in my collection of detectors. The past ones and the current ones.
What Charles said, the p/p has to be pressed all the time. But with some practice there is no need to do this. I just use the p/p to have a clue hoe deep a target will be.
And about the disc let me say, I was fooled may be one or two times by deep man made iron. So what I do is I don't use the notches as the machine has four tone ID. Notching out iron can cause false signals or better call them spread signals. Some detectors like a DFX or XLT can show them on the display. These can be misinterpreded with the notch up as good targets on the CZ's.
Having the full signal while using NO disc/notch in ID-mode will show/sound the full information of the target. If the sound is broken or scratchy (confirmed by another sweeping angle) I'll move on.
Using the IDXpro and the MXT I was fooled more often by deep rusty irons.
Hope this helps a little.

Hi, I am holding the pinpoint button in continuosly and the unit fades back to operating mode so I am thinking maybe the detector is bad. I have tried hunting with it in iron discrimination mode only but most of the places I hunt are pretty trashy and the non-stop chatter drives me insane after a few hours.I was thinking of getting a 5 inch coil for it but on Tom D's CZ site I read that there is a good chance that the ID capabilities will be lost or messed up with a 5 inch coil. I am really not wanting to dump $100 bucks on a coil for this machine as it is now.Maybe I need to send it back for a check up? Thanx again.
Jezz,
I have been using my CZ6a since 1994 and can honestly say it is one of the best machines I ever had. The key to CZ's and not being fooled by iron is to NOT run discrim high. Keep the disrim at 0. Part of the problem is, when running disrim higher than 0, a lot of times the iron bleeds through into the mid and high tone, but since you cannot hear the low tone due to it being on 1 or higher, you get fooled. If you do run discrim higher than 0, I would suggest each time you get a deep target with a high tone, switch back to 0 to see if you get the iron low tone. If you do, and the target is not a REPEATABLE high tone from multiple angles and gives off a low tone, it's probably junk. However, if you are in an area where there are indian heads and deep silver, I suggest digging all deepies. You never know. That is part of metal detecting.
As far as the pin point goes, be aware its a VCO pin point that can de-tune the target be continuously pressing and de-pressing the button as you sweep very slowly. You can size the target that way, and you can distinquish lots of iron and nails by the fact that as you detune, the size of the target stays pretty large. Coins and smaller round objects de-tune to a very small spot, right in the middle of the coil, and always at the same location. Sometimes iron targets tend to 'move', ie, are not in the exact same spot when pin pointing and detuning. You should practice sizing up coins, tabs, nails, alumium can tops, etc. to get an idea what a coin sizes as, and what smaller targets size as in relation to larger ones and iron.
If possible, I suggest trying to get the small coil and work that thing in the trashy areas and places where there is lots of iron. The small coil still goes deep, you can raise the sensitivity up a tad and it can sniff through the garbage and get some deep silver.
Last thing...sensitivity. Don't use too much. When I first got my 6a, I had that baby cranked up and thought I was going to find all the deep silver, and all it did was false and have me chasing deep iron. I learned, lowered it to start off, kept discrim at 0 so I can hear the iron, and started digging lots of coins. Also, if you do raise the sensitivity up, you HAVE to slow down your sweep speed. When raising it, remember to ground balance again. I think it's imperative to know that every time you up the sensitivity.
Hopefully your 3D does not need a check up, and all you really have to do is practice a little. 20-25 hours on it is not nearly enough to start reaping the real benefits. Took me a long time before I felt confident with my 6a, and after yesterdays beach run I had with it, ended up coming home a buying another used one.

Thanx rover I will give your suggestions a try I am not ready to give up on it yet. The pinpointing problem I do not believe is a retuning problem as I have had many detectors with this option, my CZ3D occasionally sputters and crackles several times with the pinpoint button held down and then fades to the normal operating mode-both in salt and enhanced modes.Also I do not understand why it cannot pick up some of the coins it detected in the ground once they are in my hand in a handful of dirt.I will defenitaly try your suggestion of "thumbing" the disc knob to 0 next time I take it out.Thanx again everyone for your input!

Hello jezzowhat. Sounds really your detector has some malfunction. I'd give the good people at Fishers a call or send 'em e-mail. The last question one I had was anwered within 4 hours. (in the week).
For having some more clarification you also can ask NasaTom on his site. He's a very nice guy and will answer every questions personally.
And welcome aboard. (sorry I forgot my decent education.)
All the Best
Hi
I'm sure you have tried these things but just in case.
Try a new set of batteries. Some times when the batt's get low the detector will act a little funny
Disc 0, Sen4
How did you ground balance your detector, the bobbing method or auto method.
Once you have grnd bal. the detector, tap the coil on the ground and see if you get a false signal, and also wiggle your coil wire and see if you get a false signal. If you get a false signal then it could be a bad coil or coil connector.
If you feel it is grd bal properly, disc 0 sen 4 and no false signals then I would think you have a faulty detector.
The 5" coil should ID exactly like the stock coil. The 5" is a KILLER coil. If you have to send it to FT for repair have them match the 5" coil to your detector. I believe they have to be impedance matched to ID correctly.

Just checked my test bed 8" silver dime and held the pinpoint button for 15 seconds and the 3D stayed in pinpoint mode... I suspect there is an issue with your machine... Bummer... I agree with Turtleman about the 5" coil, that little bugger is a killer in trashy sites... Didn't know about matching it to the machine though... Must have gotten lucky as that little coil has found many nice items... Did notice the 5" coil didn't sound off on the 8" dime, in my test bed, without upping the sens from the recomended 4.5, disc0, to about 7... Correction, the 5" coil sees the 8" dime with a sens of 4.5, but if I didn't know the exact location of this dime, I wouldn't detected it with that low sens... I would have detected it with a higher sens, even if I didn't know its location... One of the guys at a local detector shop advised me that a higher sens widens the signal at depth and lessens the need to overlap the sweep... The higher sens does tend to signal deep rust, but using disc0 and high sens tends to lessen the false signals...
With that being said, me and Mr 3D are out the door to find the deepies...
