CZ3D for a CZ20

[triplehooked]

Ok fellow members. This is a spur of the moment post, and I'm relying on your opinions on this one. I have an offer to trade my CZ20 for a CZ3D with two coils and that has been calibrated by some Thomas Dan. guru.... My 20 is a hot machine, pretty deep even with the 8" coil, but my water season is coming to a close and I would prefer a 10" coil for my next CZ water detector. I love hunting older homesteads and have permission for quite a few to keep me busy. So my question is not so much the monetary value of the trade as to the performance of this land machine for old coins and possibly on and off trashy sites.... I've heard that trash is not its strong point.... What are your thoughts?

Thanks,
Travis

Travis, you are asking a bunch of guys who love our CZs. I hunt with just the kind of machine you are thinking about. I hunt enhanced almost 100 percent of the time. I love hearing a four way repeating signal when checking a target. I do dig some trash, but do with all of my machines. The last two days I have hunted the strips along the curb in my neighborhood. I pulled about $4 in change and dug very little trash. I was using the five inch coil. Like anything else when you chase the iffy signals you are rewarded and cursed at the same time. The CZ will do almost any type of hunting fairly well. I say go for it. If you are getting a TD calibrated unit, especially if it is a 1021 serial number you owe it to yourself to give it a shot. Try it, they have great resale value, especially when calibrated. Please let us know if you join the family.

That is based on your statements of the water hunting season ending and the fact you want a 10 inch coil on your next water unit. I have a CZ20 with 8 inch coil that is super and would never sell it as I like using the 8 inch coil in the water. That is just personal preference.

The calibrated 3D with 2 coils will be a great unit in the old homesteads. Is one of the 2 coils the smaller 5 inch coil ( hope so as that coil will be the best one for nail infested areas in those homesteads) ?

Yep, 10.5 and a 5" for the coils. Although it's not one of the older/hotter machines as it hits about 9.5" on a dime, still not bad. I expected a bit of a biased view on this one, but I didn't know anything about the CZ3D so I figured to ask the folks who are using them. My main concern was how it did in iron rich sites as that is what I have run into with these older homes, ie tin roofs rebuilt a few times along with various square nails lying around from long gone woodsheds and such. I know that all detectors have some issues with iron due to the halo effect of the older stuff, and I expect to dig some trash. I do enjoy the CZ20, but with most of the lakes I have hit this year (including Lake Michigan) coverage is key. Thanks for the input folks, I appreciate it. I'll let you know if I get the 3D.

I am a HUGE CZ fan, but I mostly hunt salt water beaches and parks. If you are really going to be old homestead hunting that has a lot more iron in it ( ie, rusty nails, iron fragements, etc.) you may be better off with one of the F series detectors. In those ares of concentrated iron targets, a unit like the F75 with the small coil would be ideal. The F75 has a much faster recovery speed, uses a DD coil and has a lot of options that can help you ID non-ferrous targets in the mix with iron.

If you do use a CZ in those areas with a lot of iron, make sure you use the small coil, and run in 0 discriminate mode so you can hear the iron, so you won't be fooled with iron wrapping/falsing and thinking those false high tone signals are good. You will dig a lot more iron ( ie, false iron high tones that you think are good signals) NOT hearing the iron on a CZ ( discrim level 1-6) as opposed to hearing it ( ie, where you can hear the low iron tone mixed in with the high tone which can only be revealed running in 0 discriminate mode). Hope that made sense !

As always, repeatable high tone signals from a target, swept from multiple angles, has to be dug.

Tripple, here is my take. You can send your CZ-20 back to First Texas and for under 400.00 you will have a CZ-21 WITH a 10.5 inch coil AND a one year warranty. If its that hot, might be hard to give up. A conversion to a 21 is 299.00 and you have to add a new coil. Call Felix and confirm the price of one but you will have a new machine with a 1 year warranty. Your call and the best of luck to you.

Yeah sure thanks Scuba. NOW you chime in that I have already made the deal.....lol.... Thanks for the input.

I agree 110% with therover. He has confirmed what I see in the field regarding the 3d's.
I use the 75 and 11" coil for around old home sites where iron is abundant, then put on the 5" coil for better separation.
Further away from the old homes, I'll switch to the deeper cz3d.
I have the 4" for the cz but I believe the 5" on the 75 with faster recovery works better.

Well, the CZ20 is gone and the CZ3D is on its way. We'll see how it works in my neck of the woods. There is an older fairground nearby I want to hit with that 10.5" coil, then retrace with the 5". Any tips from the CZ gurus? I'll assume from the previous posts and what little research I have done so far that this detector likes a slower to mid sweep speed... I've owned and Explorer so that shouldn't be an issue.. I also see to run in 0 disc. per therover (thanks,btw) to help discern deep iron from the good stuff. Any other suggestions besides get out and hunt! Ahh the waiting game itch has set in already.... I'll be stalking the Fedex person...

Triple,

Since you have run the CZ20, then you already know how to ground balance, which is important.

If you are running in enhanced mode and start running into smaller aluminum and pull tabs that hit as high tone ( due to the way enhanced mode works ), you can switch back to normal mode and re-scan the target. A lot of the high tone aluminum in enhanced mode will hit as mid tones when switching over to normal mode.

Low and slow is the way to go and hit those targets from all angles and dig all those repeatable high tones when coin hunting. If you are relic hunting too, then dig all repeatable hits except the low tones. Investigate all low to mid or mid to high tones as well. Any target where there is more than 50% of the hits as low tone is almost always iron, but ya never know. The deeper targets will sometimes hit with low tones, so if you are in an older area and you are getting mellow, deep hits in the 10+ inch range and there are low tones mixed in with high, you should dig them up. I have hit a lot of DEEP silver this way. You will dig up iron, but you don't' want to miss some of the good deepies, especially if you are in an older site. You may bag a key date or semi-key date coin this way.

Use the pin point button to size up the targets and if the target does not pin point in the same spot on several tries, lots of times that is an indication of a elongated iron target ( if the target has low tones mixed in).

All in all, you said it....get out there and hunt !

 

[therover]

A CZ and F75 are a great combo. I have debated getting rid of my F75 LTD because I mostly beach hunt and won't be using it for the next 5-6 months now that the beach hunting season has started for me. But knowing how it does much better in certain sites than the CZ, I am hanging onto it.

It is a good dry sand unit too, and I have used it in that application with very good results.

Thanks for the info therover, and everyone else for that matter, very informative and much appreciated. My property includes the small town gas station that closed down sometime in the 60's. I've hit it pretty hard with a variety of detectors including a Vx3, Explorer SE, and Vaquero. We'll see if the 3D can pull anything from the depths.

Well now that you have traded time to Google Tom D as he has an excellent article on using the CZ3D....also Mikes CZ page is a wealth of info relative CZ's and well buy a longer digger...before you hit the turf....although CZ's are easily masked may be the deepest unit on the planet coil for coil and although not an F75 fan many do well with them and well learned will compliment your CZ well...
