CZ-3D Acting Strangely

[okie-colin]

The last couple of times I have my CZ-3D out it has acted very unstable, signaling almost constantly. Turning the sensitivity down, or switching to the Salt Mode has little or no effect. If I turn the the discrimination up to six, the signals would decrease, but every high coin signal I dig turns out to be rusted iron, usually a nail, although I am beginning to recognize those one way double beeps. Meanwhile the guy next to me with a Minelab Explorer is digging coins. These are older sites with only a normal amount of trash and yes I did repeatedly ground balance. I have air tested the machine and both the target ID and the discrimination functions perfectly. I have also done a limited test garden with buried targets that worked correctly. Out in the field this thing just seems to go nuts? Whats the deal?

Minelabs "crosstalk" with a Fisher CZ. I can't remember at what distance they'll crosstalk. For that matter, you need to stay a good distance away from someone else using a CZ.

Not close at all. The Minelab was not interfering and it was the only other detector present.

I got the same with my CZ 3D i posted similar earlier this week.
I live in the UK and i used to use a CZ6 this CZ 3D machine seems to be hard work

I have ground balanced it useing the 2 methods as descibed by the manual, i have only had the machine some 3-4 weeks, i got fed up with the first one i sent it back to the dealer who replaced the machine for another new one.
The second machine does the same as the 1st, the same as you descibe
I spoke to Fisher last night he said turn the sens up to between 8-9. Bobbing ground balance is the best

Today i have been in a farmers field, and i dug iron on disc 3,, it was very deep and i found the smallest peice of iron you could imagine. I have to say that i had ground balanced it the bobbing way and had the sens at 8 it worked fine,, then about 30minutes later it was all over the place again as you descibed. I ground balanced again and it seemed to make little or no differnece.
Like you might of thought, i thought it was another faulty machine , i do think its very sensative and it certainly is deep,, i have just started getting used the the single iron tone.
Before i spoke to fisher i was running the machine on 4 sens it seemed to quitern the machine alot, yet obviously depth is lost,,, or so i am led to belive.

I would stick with it i dont like the constant tones i get when at disc 1-2 i think it has a problem with iron personally

On a lighter note i am told the Minelab sov II is great on flat fields but has no depth whatsoever on ploughed fields so i am told

hope this helps
