your average sens setting is,,,
- Thread starter grouser
- Start date
Seems weird when sens. goes up to 10 but between 4 and 5 as unit becomes unstable after that..CZ70 was the same way on many of them as I believe they vary if early or late CZ70...
Older CZ's I used averaged 6 or so and in some areas got them up to 8 but never found an area where I could use one maxed out..
Again run your sens. as high as you can and still have a stable unit and yes a CZ3D set between 4 and 5 will go as deep as older CZ's with higher setting so sens. parameters were changed in the newest model Analog and digital CZ...CZ3D and CZ70.....

With the 8 inch coil 4 to 5, and with the 5 inch up to 7. Mike.

grouser, yep, the best way to run the CZ is in zero disc. If you tune out iron you will be digging more square nails that want to give you a high coin reading because you won't hear the iron. After a couple hours use you will understand better and see the advantage of hearing the iron sounds.
I never move my disc off zero on my CZ5. Good luck with your CZ3D, you are going to love it..............

well, normally just a low tone if you are running zero disc., but if iron is discriminated out you won't hear the low tone, but it could hit on high tone and fool you into thinking it is a coin. Like I said earlier, after a couple hours using the CZ3D you will understand what I'm telling you.
Basically you are listening to the iron to keep from being fooled by it. You will dig much less trash this way. Does that make sense? You can pick good targets out of the iron by listening for a high tone that repeats between the iron grunts. I have found several deep dimes on edge this way.
Glad to help if I can, so feel free to ask any questions you have. HH...

If you have a good analog CZ you should be able to run wide open in open areas with little trash and coins are deep. That's how I would run mine. In trash filled parks I would run just under 5 at 4.8. That's where tom dankowski says maximun deep per radius is at or something like that, But that's where I run it in heavy trash. That is the thing I discovered about Los Banos analog CZ's is they can be run wide open in my area at least. Thats why I like them so much.
I was out yesterday with my new 1021 cz3d in a old farm field that was just cut for hay. The cz has never been sold from the dealer. He has had it for years and no one ever bought it. It was at his store when I bought my f-75 a few years ago and I've been contemplating the last couple years whether to buy it or not. Well I finally broke down and purchased it. The lifetime warranty is still good, confirmed it with Felix at Fisher before I bought it.
After running the f-75, one has to put on the brakes a little with the cz...that's not easy when your use to going full out with a faster machine with a larger and different coil. I noticed, like you guys said, about the sens above 4.5 and disc on 1. The high falses were there. I did drop the sens to 0 and welcomed the grunts. While in the field I dug an 8" deep plug and buried a clad dime to see if it would pick it up at 4.5 sens. It didn't pick it up at first, then I worked out a low tone. I then cranked up the sens to 8 and it hit all ways. Turned it back down to 4.5 and then it picked it up with an occasional high tone.
There is no way I can hunt a field like this and not be able to crank up the machine...I just feel like I'm wasting time and walking over deepies, I need to get deep and hunt it while the field is short. I had hunted around the yard in the past with the 75, and it produced large cents, Jersey coppers and one half reale, so I know the fields hold old coins. I cranked up the sens like Harold mentioned, and the cz seemed ok and made me feel better about not missing anything.
I was digging mid to high tones to familiarize myself with the cz and I gotta say when the needle goes to pull tab or foil, 9 times out of 10 that's what I dug.
The sun was hot and there was no breeze, but a few passing clouds were helping cool me down along with a few breaks and plenty of water.
As I was trying to keep my swing at half speed (compared to the 75) I got a nice short quick LOUD high tone that buried the needle. I guessed it was shallow because you can really tell by the great audio of this machine, the deep whispers to the loud shallow targets....sweeeet audio, love it. I pinpointed to see if the tone matched the debt reading and sure enough the needle went to 2 inches. If it's a coin, it should be near 2.
At about 2", I pulled out a 1724 Britania. The date was the clearest thing on the old copper coin, that doesn't happen often enough. Britania was in good shape but the King on the obverse was worn and barley visible.
You never know in farm fields, some coins are deep and some are shallow because of the plow. Around here in Pa, many farmers are not plowing every year, especially hay fields.
I'll wrap this up by saying I'm glad I finally pulled the trigger and bought the cz that stared at me for years from the rack when I went to visit the store. It's like owning a classic of something and I'm sure it will be cleaned more often than the others. Any experienced advice, I'd love to hear and learn, thanks guys.

If you are hunting in an area where old coopers and old silver are around, check out some of the fainter, small iron tones that are deep. CZ's will mis-ID deep some coins as iron. The key is to size up the target using the pin point button via detuning until you can get an idea how big it may be. If its small, deep and faint, it may be a coin even if it's low tone IDing.

I would go for it I think he charges 100.00 with return shipping included. I know times are still a little though out there for some of us none yuppies,But if you consider how long CZ's last being build like a tank and all,and the finds you make it will pay for itself. And it's still A lot cheaper than most top of the line units.
so the trick here is the faint iron grunt,,,, may be a keeper ehh?therover said:Just the nature of the beast.

I don't think he calibrates digital CZ's. But I would ask.
