If the CZ's didn't love deep rusty nails and small Iron..........

[Elton]

I would be all over getting one. Unfortunately in my part of the world old farm pieces of iron discards are in most of the ground ,and it's not fun digging [size=large]all that iron[/size]..Or the deep [size=large]rusty nails[/size].That all rang in as a high coin target..

Best nickel finding machine I ever used.....also to a degree a ring finder.. if anyone over the years has figured out how to get around all that iron please post it up..

When I was younger I had and loved a CZ5 I owned.. It was hot..but it too liked the iron and nails ..the up and downs, and all the digging didn't bother me then as it does now...My legs just can't take it anymore...

Hey Elton,I think you might want to get you another CZ. Not calling deep iron or rusty nails with a high tone would difficult for any brand detector. I am an old coins/jewelry hunter and after years and years of use ,I almost never dig any rusty junk iron.My secret you ask ??,well simple ,pay close attention when you pinpoint a target. When you pinpoint the response should be very small ,coined sized.The iron junk will always have an elongated pinpoint- not small ,try it . CZs are old,are analog,but are extremely effective!! I have tryed many brands,but my CZ5 is my go to detector since 1993. Just run with zero disc, you only have to hear 3 tones low medium and high. HH. Tony

Yup ... in pinpoint it sounds much like a PI. Walk around the target and get a double blip along one axis is a good clue, as well as not being as tight of a pattern. For me the biggest clue is found with coil speed. Disc has to be on 0 to listen to all. With what most use as a normal sweep speed, lots of iron beaks high tone and stays there. Slow the coil speed way down over the target and see if it goes to and stays low tone. Unlike the F70 / 75 that like higher coil speed to ID well, the CZ seems to respond with better information with a slow, sometimes very slow coil speed.

Thanks Tony......... a person I know has a Cz for sale......... I may, or may not grab it.. I am very happy with my F-70 so may not want the CZ..

I'm thinking on it ..LOL

Elton, I think of the cz3d as closer to a specialty detector rather than an all-purpose machine.

More than moderate trash/iron and the cz is put away. Most newer detectors unmask and separate better.

Both points in previous posts about slowing the sweep speed and pinpointing to reveal small iron are very true.

Slowing the sweep speed down will usually reduce the percentage of high tone sweeps if the target is iron.

If you still get fooled after pinpoint sizing and slowing the sweep speed, if the target is in the side of the hole after pinpointing it is invariably iron. Pinpointing with the concentric coil and inner ring is remarkably precise, a non-ferrous target will be at or close to the middle of your plug.

Nothing written in stone, but most front yards of older homes in my area can be effectively hunted with the cz. It's the detector I try to use first. Once I get up close to the house, the construction/renovation nails and other small iron usually gets heavy making another detector a better choice. Back and side yards can go either way depending on how trashy they are. When the houses have right of way strips, those can go either way too.

If I don't know the ground conditions where I'm going to detect and I only want to carry one detector because of security or heat in a closed up vehicle reasons, than the cz-3d stays at home.

I don't dig much iron with the cz-3d. The key for me is not forcing its use in trashy areas where it's not the best choice.

Like you Elton, that uninvited guest "Arthur" detects with me more often the older I get.

Marcomo, you mentioned iron trash but how is it in the modern park setting that may be more riddled with aluminum trash and/or bottle caps? I'm looking to maybe buy one here locally and just want to be getting a great coin shooter in the trashy modern parks. Otherwise, I'd have to consider a different machine altogether.

I also hunt 0 disc when in a questionable area with iron. . But I will give it my best shot for a masked coin and hunt slow between the tones.

 

[marcomo]

Habanero, I love the cz-3d but in a trashy park, regardless of whether the heavy trash was ferrous or non-ferrous, it would not be my choice.

Heres the drill must hit from at least two angles while walking around target, second if you dig a plug and the pinpoint seems to move..move on...3rd if your not sure just move to zero disc and you will hear a low iron tone in between the high tone....take more time from the top and after a while you will just know its a coin....we all get fooled but I seldom dig any iron...

 

[Elton]

I'm not digging but a little iron..and it for certain identifies it in the ground as iron.... More to my liking..
Now don't get in a tizzy here everyone who runs a CZ.I am not saying their not a great machine..They have time tested, and proved their worth.. Their just not top dogs where a lot of iron is in the ground.
I have that condition in my dirt........ Thanks all for your great responses............

Iron wont ring in as a high tone. Iron rings in as a low tone. Otherwise you have a broken detector. What will happen is that good finds, like gold, will ring in as a low tone if they are deep because all detectors have problems discriminating as the target get deeper. Now if you have multiple targets in the same spot the iron ones will ring as iron and the rest not. Some people like hearing the iron with the CZs and others do not.

adamBomb,
If you haven't yet dug up a rusty nail that signaled as a good target, you soon will.

When iron rusts in the ground, it leaches into the adjacent soil and creates a 'halo' that can, and indeed will often false as a high tone...with most motion detectors.
This usually happens on the rusty tip end of a nail or piece of wire. (It is this effect the posters are referring to.)

You can sometimes get a double hit (high tone false) from both ends of a rusty wire, and that can sound a lot like two targets, or one coin on edge.
The effect is far more pronounced when the soil is damp, and because of the way the CZ is designed, it's more susceptible to falsing on these rusty iron halos.

Unfortunately, since the halo can be quite large in relation to the size of a coin, we can end up digging a rusty square nail from some pretty impressive depths!

Running any machine so that you can hear the low iron grunts will help expose those fake high tones, as will carefully listening to the target characteristic in pinpoint mode...(a technique that is under-utilized).

have fun,
mike

I have to agree with Mike and Elton. I've owned 3 cz's and regret selling the last 2 but the iron wrap around will give you a false high tone. I usually could check target from different angles and tell but not always!

did some more reading and it turns out you are right. i use a cz21 on the beach and i guess there are not many nails around...then again i pretty much dig up everything that sounds somewhat faint anyway as i dont trust discrimination for deep targets.

adamBomb,
You've got the right idea about not trusting disc at depth...or, as some say, the best discriminators are your eyes and a digger.

Living in the highest land-locked state in the union, I can only dream of some day beach hunting.

Good Luck and have fun!

My tejon worse than my CZ's on deep rusted iron.
My T2 not the case,it has the ability to let you know.

Not one bit of a problem for my 6a,actually better than any machine I have in iron,just don't notch out iron.
Just tested all my machine with a Morgan at 8" in undisturbed ground with a bent rusty nail.
The only machine to signs with 100% confidence was my cz6a,next my T2 with the 5" DD coil.
Nothing else worked period.
