My question is : Do you ever find good coin targets that do not give a repeatable signal from different angles? With other detector it seemed to pay off to dig iffy signals maybe a one way hit or getting a repeatable signal from one direction but with the CZ5 these targets are always rusted nails. I know that I have read that circleing the target looking for repeatable signals is a good way to reduce the nails that the CZ5's love but I don't want to miss a deep coin. So far I haven't found any coins that didn't give good repeatable signals from all directions, even the deep ones will repeat but I was curious about if other users have found good targets that are non repeatable or one way signals. Thanks for the help.

We all dream of finding that super iffy signal that gives up a great find. My experience has been that good targets, even deep ones, give a repeatable signal from all four sweep directions. I still dig some of the iffy ones hoping to be amazed and astounded but I can't recall ever being rewarded for digging the questionable signals. I guess there could be a first time so I probably will dig one once in a while. When I read about people complaining about digging junk with the CZ I think about the sweep from all sides advice. Generally, if you are digging too much junk to suit you I would say you are digging some non-repeating signals. Anxious to hear what others have to say.

That has been my experience too Don. I still dig some thinking something will be different especially if they sound really good from one direction and are deep signals. Yesterday I dug a signal that was saying it was 7 inches deep and it only repeated from one direction but could get a one way beep from another direction .... NAIL !!! That's what got me thinking about this question because I have yet to dig a good target that was not repeatable from all sides. Thanks for your response and hopefully we will get a few more.
If things are slow and coin is real deep my good finds are far and few between on one way signals...Do remember a silver dime or half dime is awful small and on an extremely deep one might have to work to get it to repeat from two angles and certainly not repeatable from 4 angles. Certainly a worn coin-tiltled coin-coin near junk may not repeat more than one way but again unless things are really slow unless it repeats I just move and I am talking left to right swing not a to and fro as it seems a to and fro is not always dependable.
I recently went to a very trashy site looking for deeper coins - that day I had a lot of patience and ended up digging most of the "good one-or-two ways" repeating faint high-tone signals - with the Disc on 0. Sometimes I would get an irony "blip" when trying to go to Disc of 1, but they were dug anyway. Out of maybe twenty iffy signals that day, I pulled out three 1930s Wheat cents which also had nails in close proximity to the coins. One target was repeatable but had iron lowtones mixed in and read 6" deep indicating "zinc penny"...I pulled three nails out of the hole and finally popped out a nice green 1936 Wheatie for my efforts.
Sorry about the ambiguity here, but what I've found with the CZ line is that deeper iron, most deep cast aluminum (not foil or tabs), and deep 6" plus copper or silver coins CAN sound very similar which will make you dig a lot of junk. I recently purchased a Deus and marked a lot of these iffy signals from the CZ and then ran the Deus over them - most of the time it was in fact nails, but a few were indeed deeper copper coins.
Depending on the site there's always a chance that a coin can be masked by some nails, or other iron - and if you have the time and patience dig it. I wish there was a better way to handle iron with the CZs but in my experience it's the nature of the beast.

Have had similar experiences with iffy signals ending up being trash near a good target. Experienced that with most of the detectors I've had; not just a feature of a CZ.
I'm not saying that this is a weak point of owning a CZ. I think of it more as a strength that when there is something good it will sound off. I have dug several targets in the area of trash that still sounded good.
after using all "high end" machines over the years, they were also set up to accept everything. I always come back to using a CZ, due to it's sheer power and much simpler analogue operation. Doing the "nail board" test and observing how a nail parallel to a coin or minie behaves when swept the length of the nail (no good signal) versus across the pair (good and bad readings) you will hear both signals across USUALLY by not sweeping the long length of iron........I have no problems with a high conductivity coin UNDER an iron target if not too large.....you have to hear iron with the higher tone to find the goodies. Set on 1 or above will often result in the good target being lost in the iron "null".....bent nails can throw a wrench into expected usual behavior also....my BEST search sites are where a pre-1900 structure once stood......just an observation!

A good thought but searching for silver in high disc leaves you without the confusing other tones and after many years hunting with a CZ can usually tell a good hit from a bad one. As far as the nail board test how can you mimic nails and coins buried for 100 years comes to mind. In any case whatever works and for those that are not aware a CZ unlike most gives little or no depth loss in high disc. Many do well with high or low disc. and a lot depends on the hunter using the unit...
PS: If hunting in high disc and getting an iffie signal always can switch to zero disc if needed to dig or not.
YES! some deep targets will give an iffy signal, buttons, crotal bells and indianheads have all come in as iffy signals on my 3D. My strategy is
going very very slow in heavy iron areas, play with that singnal for a bit before digging it, try to lock onto it better from all angles. I use the shooter coil at cellar
holes when doing that, as long as your sens. is high enough to go deep without falsing you should pick out some good stuff. The 3D has 5 tones so it also
depends on what mixture of tones its telling you, a good high tone bounce is usually a good target, unless its iron.
It was my observation, and to use your point regarding iron buried for a long period of time, my opinion is further supported due to the large oxidation halo (read rust) can envelope that silver signal, thus my hunting in zero disc. Yes it is noisy and fatiguing but that is how I usually hunt, but do "cherry-pick" on occasion......again imho Mark Sowder
I have a site that was a picnic grounds from the later 1800's up to about 1945 or so. It was loaded with coins of all kinds.
After many years of pounding this site hard, the coins are slowing down but still there.
Hunting with my CZ5 with a 10 1/2" coil I was getting iron grunts with a high tone that would repeat a couple of times after just barely moving my coil over the target. I was running zero disc with volume cranked all the way up and 8 sens. Always run zero disc and listen to the iron, it helps.
I opened the plug and at about 10 inches saw the edge of a silver dime standing at an angle in the bottom of the hole....1917 mercury dime. Moved about 5 feet or so and another signal just like the previous mercury dime.
Dig it and another old mercury dime on angle in the hole at about the same depth as the coin before it. So far these 2 coins are the only ones I have found digging an iffy signal, but it can pay off. If you hear a hightone anytime in the signal dig it....HH
Something about the design of that coil helps with hitting deep, on edge/angled coins.
I agree any deep faint iron tone hit with a faint/mellow high tone mixed in needs to be dug. Especially when on sites where there are potential for older silver coins.
I think most good targets will give a good repeatable audio responce. I check by hitting it at 90 degrees.For deep iffy targets,the pinpoint mode can give you a lot of info. Iron,rusty nails,trash tend to have an elongated continual tone that is a dead giveaway,where a deep coin size target tends to be a short / sharp responce. I run zero discrimination and if i hit a hi-tone / low-tone, when i check the pinpoint and it shows that there is 2 audio responces very close together ,more often than not I find a good target masked with Iron/trash.I am an old school concentric coil type .I think the conical detection paturn coupled with the CZs analog audio ,still is the best coin hunter and is strong competition to any High End Detector availible today HH Tony
