CZ-21 SALTWATER SETTING

[Arboman77]

Hi everyone,
I have a question about the CZ-21. My question is while in discrimination mode my detector starts giving false signals as soon as it touches the saltwater. In all metal mode it does not false at all. I am new to this machine, only used it about 10 times in the last 2 weeks. I have tried turning the sensitivity down to about a 4 and it still gives false signals. Any help would be great.

What do you have your ground set at?

Since you say it is quiet in autotune (all metal), I don't think it is a bad coil. 4 should be OK on the sensitivity, but to make sure, turn it to 3. Then try setting the ground balance. Adjust ground balance to the wet sand area then try the water. If you can't seem to get it to balance, slowly move the ground balance through the range while moving the coil in the water. If it doesn't quiet down somewhere on the ground balance setting range, give a call to the factory.

CZ's are normally very quiet hunting unless sensitivity is too high or the ground balance is way off, or both. There is that bit of a chance that something may not be right with the detector.

in salt water my machine only sits at about 4-4 1/2 on the sens... Trick is get ground balanced like tvr said. Mine usually stays at 10 on GB where I am though... Anyway just turn down the sens until you dont get any falsing and it dosnt take much moving of the knob to change the setting a bit GL with it.

Thank you, I will try this out. The unit works great in fresh water with sens set at 10. I think I had my ground set at 10 when I went into the saltwater. Another question, with the sens only being set at 3 or 4, does the unit still punch deep in the saltwater at that setting. Again thanks for your help.

CZ is deep at virtually all sensitivity settings. You can gain some depth with higher sensitivity settings, maybe an inch or so, but the main thing is to keep it stable, not falsing, and work with fairly slow coil speeds.

Do this... Find a target at a good stable setting... then turn down the sensitivity little by little until you cannot get a signal on it. Finally dig the target taking only little bits off at a time to get an idea on depth... This is what I do to see how the sensitivity reacts to the objects in the sand.

My 21 still finds coins at the beach deep on low sens levels. Hope this helps

I just got one also. Seems gb is always best at 10 at the beach.

Thanks for help.

mine is set on all the factory setting and I hunt in auto tune, and dig everything, by size
