CZ-3D first of 3 qustions or understandings

[WV62]

It has been to dry to hunt much so I have been doing a read through on all my manuals, sometimes I find something that turns on a light bulb. The CZ-3D detector is my newest add to my lineup and the least used. So far I have 3 questions or understandings that I could use a little help on and just to keep the info from getting all jammed up in one post I plan on doing 3 post.

Question 1, on ground balancing/sensitivity:
Starting on page 9 of the manual it says something to the effect that if you increase the sensitivity level you should recheck your GB.
Then over on page 11 under GB bobbing method, it says to set the sensitivity to a slight threshold hum and then it goes into ground balancing.
Now let

Realize that when you are going to ground balance the CZ using the bobbing method, the sensitivity is going to be close to max, if not max, when doing so. When you put the CZ in autotune mode ( ie, all metal) for ground balancing purposes, you should/need to up the sensitivity to max so you hear the distinctive threshold warble.

When you switch over to discrimination mode, you will always in most all cases, lower that sensitivity setting. So when you are done ground balancing via the bobbing method, with sensitivity setting at 10, and then swtich over to discrimination mode, you will always lower it to at least the 4-5 setting. If you want to increase the sensivity and are in the same general area that you ground balanced in, you can just increase it....really no need to re-ground balance it. One cool thing you can do is, use the pin point method to ground balance to check if the unit is off. Simpler but not as precise.

The CZ will tell you when you need to re-ground or when you are running too hot. It will start to false.

Running CZ's since the 6a came out, and I figured 4 main things about the CZ's.

1) Ground balance is crucial to eliminate falsing.

2) When running in discriminate mode, always run at 0 if possible...you want to hear ALL targets, and will get fooled a lot less on iron that wraps into the high tone range, because you will hear both the low and high tone of iron. When you run discriminate setting 1-6, the low iron tone is elminated, and in cases where the iron wraps, you will only hear the high tone and think it's a good signal.

3) Sweep all targets from multiple angles, and any repeatable high tones or mid without hardly any low tones mixed in will be a good target to dig...may not be a coin or gold, but it won't be iron.

4) Slow to moderate sweep speed is best.

Since you are running a 3D, experiment with the Enhanced and Normal modes when you hit a target. The meter ID may change when switching from the 2 modes and can give clues as to what the target may be. Some targets/coins will ID one way in Enhanced, another in Normal...same with some pull tabs.

Hope this helped

Excellent advise, #2 and #3 are very applicable at older sites. I dig way less iron trash since I learned these.

therover,

Thanks for all the good information, I will do a cut and paste into a word file and keep it. This one will be one that I may want to come back to as I try this stuff out. Wish I had this info when I was running the CZ-5 several years ago.

Thanks,

I took it out in the yard and it was just as you said.

One thing I did notice I tried both the pushbutton and bobbing method of ground balancing in the same spot and noted the position of the knob and it was the same for both ways.

Thanks,

Once you get used to the basic tuning and operations of your CZ... here are a couple of well known links with CZ Tips:

I was already had Mike's CZ Page, but the CZ tips page I never seen before, I saved it in my favorites.

Bobbing and pushbutton method getting the same GB setting. Sometimes I use the pushbutton method to get close, and then fine tune it using the bobbing method. One thing the bobbing method allows you to do is set it a bit positive or negative if you like, depending on the conditions and how the ground is making the unit react.
