I went to an old school today.Ground balanced the 3D and set sensitivity at 4.5,disc 0 and volume at 8(turned down the headphones).This mode drove me nuts,way too much falsing.I turned the sensitivity down to 3 and it still falsed alot.Anybody else have much success with is 3D setup?

Either you groundbalanced incorrectly or have some super bad ground...
Most CZ's which ever model allow you to run at 4 for sens. usually run around 6 and have even got it up to 8 in some hunt areas..Although Tom is a guru of sorts and enjoy reading his articles believe sens. should be run as high as you can get it. Been around CZ's since 92 and from my experience in my neck of the woods and of course my ground may differ and never had to run it under 4..Further thought another aspect is your disc. setting I think setting it at 0 and you pick up iron almost like running in all metal, turn it up one click and reject iron and would bet most of your falsing may go down as feel your hunting in an area loaded with high iron mineralization.
Always think of unit malfunction but in this case operator error stands out and would try the above before anything and should have a stable unit..Remember all metal in any unit is noisy and used by many
to get some more depth but believe me a CZ is one of those units where you can just accept coins all and not loose a tad of depth..
If all else fails which I doubt I hope a clubmember has a CZ and see if you can try it out in your hunting area using the same settings and see what happens..Let us know how you make out...In addendum Nasa Tom knows CZ's or metal detectors for that matter and his articles and such are good learning tools...Whoops one more thing volume is your choice and should have no bearing on the problem..I like to run at 10 to hear deepies but many run it at 4-5 to give a modulated effect( shallow is loud and deep is soft)..

Kickback,
When I am at my house with my 3D, I can't turn the sens above 3 or it falses like crazy. I have tried everything and have determined it is just the area. There arn't any over head wires or anything glaring that causes my problem. But if I go to the in-laws house that is about 3 miles away, I can turn the sens all the way up and not false at all. Try another location and see if you still have the problem. I would love to know what causes the problem at my home...still no idea though. Best of luck.

Suggest you start with the pusbutton way and work up to the bobbing method which gives a better more accurate balance..Not as well written in the manual, but take the manual and unit in back yard and practice and in the field a couple of bobs and your good to go. Heres a tip start with volume at 10 so you can hear the audio changes more clearly. Once its balanced put volume where you wish. Remember you can ground balance at a higher number sens. and drop down but if you balance at a lower number sens. and raise it you have to do it all over again which takes seconds at best. And your backyard practice will make you a pro at balancing and when you hit the fields expect more depth and more stbility from a unit balanced dead on////

that your site is to blame (or you GB'd over some iron). I have had sites or even portions of sites that false like crazy. I don't think that upping the disc will get rid of it. The low iron grunts are what will be disced out not the high tone iron pings. I hunt my 3D exactly like you mentioned and think that it is the best way. I also agree with Dan, in that, you won't lose depth by discing out all but coins.
Just my experience,

What works for me and others may work for you or not.
You did not say what size coil that you were using, I am guessing 8".
I have been hunting a place that has many old coins, but there is a lot of modern trash with small nails to iron. The trash is so bad that it is hard to find a place to GB a 5" coil, but we have hunted this area for so long that we don't GB, we just set the GB on 5 and hunt. In Oklahoma, the places that I have hunted GB from 4.5 to 5.5, but one time I did find a place that Gb was 6.5.
I run
Zero Disc.
Sens 2 to 5
Vol 5
GB 5
5" & 8" coils.
I run Zero disc because I want to hear the low tone ( iron ).
When I run a cross a rusty nail, I hear the low tone and when the coil comes off of the nail it will go to high tone, if you notch out iron, all you will hear is the hight tone.Now you have to get use to all the sounds...
These coins can be 1" to 7" or 8" deep, because they are doing dirt work, and have moved the around.
Here in our soil, the 5" coil will hit 7" & 8" dime and a 9" half with the Sens at 3.Think of the Sens. like this,high sens in trash is like high beams in fog.
And that's on the all of the CZs that I have owned, CZ 6a,CZ 5, CZ 3d, and the CZ 70.
Go slow with the 5" coil and work it at different angles.
I have found a lot of coins with the 5" coil. And so have my hunting buddy's....Have fun.

Is it for sale? I like the Cloaking Device function. The Fire Warning Shot would be nice to have too.

Nice to smile over a cup of coffee..Really ready for bear.
To whom it may concern It was explained to me years ago doesn't tell you how mineralized your ground is by where the ground balance knob stops...Certainly no electronics guru but just go thru the procedure and it does vary from area to area and your buddy using a CZ may have his ground balance at a different knob number in the same place..My CZ's usually ground balance at 5 to 7 in NE. Pa. so usually start with at 6 and go from there. Indeed in your neck of the woods yours may differ...

Now that I'm back out of the Great White Frozen North and down where I belong, in OK.
I usually hunt in SALT mode. I've found that it makes it easier to GB, and handles the mineralization better. However, it does shift where the knob rests on the scale. Around here, I usually GB out somewhere around 7 or 8. Remember, though, like Dan said, it's not the number, but how big of a range of movement on the knob before you get a change in tone during a GB that indicates how mineralized the dirt is. When I would try to hunt in NORMAL mode up in Michigan, due to all the iron in the dirt, I would be lucky to get any kind of decent GB. It wasn't until I started hunting in SALT mode that I really started getting good depth.

We will have to meet in the middle some where and have a hunt. I live south of Norman and if I remember right, your up by Tulsa.
I did a GB a while back and the very spot read 5.5 on my CZ and it read 55 on a MXT.
I have never used that salt mode to hunt in, but have switched over to salt to check a target on my 3d.
Also, 2 CZ's need 50' to 75' between them, even if you do not hear them talking to each other, you are losing depth.

I did a test on this last Spring up in MI. I was at a schoolyard that is known for older, DEEP, targets. I've recovered many, many, Wheat's, Silver dimes and quarters, some jewelry, even an IH penny. I started out the test by continuing a grid search on the infield of a softball diamond. I was using my CZ-5 with the stock 8" coil. When I located a deep target, an indicated 6" deep High Coin hit, I marked the position with a small stick, turned my 5 off, and went back to my vehicle. I pulled out my CZ-20 with the 10.5" coil.
I started out by placing the 20 on the ground, with the coil pointed towards the target, at an estimated range of 50'. I turned that detector on. I then went to the target, and turned on my 5. In Auto-Tune, with my coil pointed towards the 20, I would get a crosstalk signal about once ever 5 - 10 seconds, but nothing I couldn't live with. I flipped the Disc. to 0 Disc. and swept the target. I could still get the target, no problem.
I then repeated the test at about 30', 15', and finally less than 10'. Each time, yes, the crosstalk got worse. However, I never lost the target until I did the last test.
I wish I could have gotten over an 8" or deeper target, but those were few and far between, and that place covers about 5 acres. I would imagine that targets deeper than 8" would become lost in the crosstalk at a greater range than about 8', but what distance that is, I have no idea.
BTW, the target ended up being a Wheat.

P.S. Norman, huh? Somehow I had it in my head that you hailed from somewhere near Ponca City. Laurie, my other half, has an Aunt in Lindsey (sp?). I've been there, once, about 6 years ago.

Allen, what we did, was on a 8" silver dime, been in the ground for like 20 years.
We used 2 CZ 5's with the 8" coils. The CZ 5 over the dime, we turned down the Sens until it just got the dime.
I turned on my CZ 5 and started moving away from the CZ 5 over the dime until my friend could pick up the dime again.
I did not measure the distance, but it was about 75'between the CZ 5's.
I have dug more Wheaties than any other old coin. A friend of mine with his CZ 3d and 5" coil dug a old wheatie a while back, it was the one everyone wants, 1909 "S" VDB.

I really believe even if they are far away where they don't crosstalk two buddies hunting in the same area may not get the same depth and stability. Read several articles on that including one on two fellows if they hunted the park alone got deep silver and if they hunted it together with CZ's were shut out of deep silver..I guess thats why some manufactures allow you to change frequencies so two buddies using same machines one can change freq. and eliminate such problems.
I always hunted with a Whites guy so really can't back up the above, but its something to think about...I do know from passing other CZ hunters they will crosstalk for a good distance...

As you know, I hunt with Craig & Steve a lot, and where we hunt is a big area, so we are spread out. All with CZ's.
I will have to test my M-6 and Cz 5, I do know if we are close and talking, the units will also talk, but I don't know how far.My X-50 seems to be ok, but have not tested it.
I also know that the MXT is bothered by the F-75, but we have not tested it to see how far.
Years ago, when we started hunting this spot, the first day there were over 30 people hunting this area,all brands of detectors, then I was using a Explorer ll,and I was the only one, the rest were Fishers,whites,Garrett's,and one A.H.Pro backpacker.Every one found coins.This was dirt that was just box bladed.
My first find was a 1897 Barber quarter and my first IH,1864.
Man, those were the good days,about 5 yrs ago.
Life is short,so many detectors,so little time.
