CZ5 questions

[Newfiehunter]

Hi Everyone!
I've owned a couple of Cz5 detectors over the years and I have a couple of questions. It is a very good machine, great depth and all but there are a couple of things that bother me. I've never met anyone with another Cz5 before so here goes.

First, the sensitivity control. It seems with the 2 Cz5 detectors that I've had, the control cannot be set over 3 without having erratic behavior. Is it just me or are soil conditions causing the erratic behavior? It seems like the coil becomes sensitive even over blades of grass and there will be some falsing. It also likes deep iron which kinda irks me, but I'll always dig em to be on safe side, even though I know that it is iron most of the time. I also own a Tesoro Cibola and it seems to be more stable and I can crank up the sensitivity up almost to the max.

Second to those who have used the Cz5. What method of ground balanacing do you use? Using the pinpoint control or the bobbing method?

Thanks everyone!!

I always used the push button method. If you don't have a manual download it from Fisherlab.com. Then follow the procedure. When you bob the coil you have to keep the coil level with the ground. Go up and down about 12 inches. Yes it does like deep rusty iron. But it's still perhaps one of the best detectors ever built.

I have a CZ6a and find that in some locations it is very sensitive to wet grass if the sensitivity is above 4. Does your CZ5 become unstable always in the same location? If so you might now have a cell phone tower or other transmitter near by.

I like the bobbing method by setting it in Auto Tune and while keeping the coil level, raise and lower the coil while adjusting the GB knob till a steady threshold is heard.

Your Cibola has a preset GB I believe and that could acount for it seeming to be more steady. At higher Sens. settings the detector is also seeing more of the minerals in the ground and deeper targets can be lost in the signal.

I've had a CZ-5 a few years now. It's not my primary machine but I find myself using it more frequently. I prefer the bobbing method to tune it. You're doing the right thing by digging the deep iron and yes, the CZ-5 loves it! But so does my Explorer the way I set it up. You may want to get it checked though, unless you have some funky mineralized soil that you're hunting, unless you're having trouble ground balancing it. You should be able to run with the sensitivity past 3 if it's GB'ed right. I run mine around 4 or 5 most of the time anyway. Increased sensitivity doe not always (actually, almost never) mean increased depth. Work on your GB technique and if you're still having trouble I suggest having it checked out.

The fact that the CZ-5 was produced for so long speaks for itself how good of a machine it is. Now even the CZ-3D is no longer being produced. A lot of people swear by the new Bounty-Fisher-Hunters, but I'm pretty much convinced that the old Fishers like the CZ series are the TRUE Fishers.... A Fisher sticker on a Bounty Hunter does not a Fisher make it.

Hi guys!!
I agree with you guys. I've been using my CZ5 for years and always use the pinpoint method. From now on I think I will try the bobbing method. It does have great depth and it is my primary machine. Found some nice things over the years.

And sandman, you are right when you are over wet grass, it does become a little unstable. I've been able to set the sens to 5 (where there is no mineralization) and I've found items as small as BBs. It is an extremely sensitive machine.

So what do you guys think about the large target alert? I've got to admit, it is a little annoying. You occassionally miss shallow coins on the surface. I've dug surface pennies after recieving the large target alert signal. Not only that you may pass over a shallow half dollar if you get use to passing over digging those signals. It is usually right most of the time though.

Thanks for your imput!

I like the large target alert though I prefer to think of it a a shallow alert due to a surface coin setting off the alert. You can tell if it is a can by the size of the signal----------usually.

The CZ20, a water machine is of the same operation except it has a set saltwater mode. I've found a few watches this way digging the alert signal.

Lift the head up a few inches, a quarter on the syrface will sound off as a large target, but it'll be a coin signal if you lift the head. A can will generally stay the same. Not 100% accurate, but it works most times for me.

Love my CZ-5!
