Ground balancing

[tonster1000]

Can anyone tell me how to do the bobbing method for ground balancing on a CZ5?

Set SENS to 10.
DISC to Auto-tune.
Turn power on.
Briefly sweep around to find a clear spot with no targets. Once you have one, start "bobbing" the coil up and down about 8" or so. Adjust the GB so that there is no change in tone on the up- and down-stroke. Set you Sens. to a comfortable level so that your machine is stable, and adjust you Disc. to wherever you normally hunt.

Notes: Sound on the downstroke means your machine is tuned postivie. Sound on the up-stroke means your machine is tuned negative. Also, you will encounter the same pitch/volume signal on a negative hot rock as you will when your machine is negative. In my iron-laden dirt up here in Michigan, I hunt in Salt mode (cuts down on falsing), and tune my machine slightly negative, to get the positive targets to respond a little better.

I hunt in auto-tune quite frequently. I've learned to tell when I need to GB again, as I start getting "fluttering" sounds that correspond to the minute changes in the surface as I swing.

Nice post Allen...I might add put your volume at 10 so you can hear the change of sounds clearly as it helps to make the ground balance right on...Right now don't worry about negative or positive just make it so little or no change when bobbing..Actually all explained in manual but to me feel its was written by an engineer and your not the first one to be confused. Allen is certainly experienced and many experiment with negative or positive and also the salt mode in bad ground. But for right now just put you ground balance knob around 5 and experiment what turning it left or right does to the sound and it will help you understand what we are trying to tell you..Confusing as heck to many but follow Allen's post and like myself you will bob several times and be on your way as it should take seconds at best..Although a CZ is a user friendly unit you indeed are not the first to be confused....When you have an extra 10 minutes or so take it out in the back yard and practice and once in the field a bob or two and you will be ready to go....Do remember bobbing is the most accurate way of ground balancing and an accurate ground balance will give you more depth and stability...

Looks like Allen has it covered. I'll add mine, which may be something you might want to print or save. I posted this here a few years ago and just pulled it back up from "My Documents". For what it's worth...

1) Turn on the machine and put it in Autotune. Find a clean area of ground with no metal in it to do the ground balance. Verify that as you sweep the coil in the test area, that there are no signals

I think Mikes post should be added to the CZ manuals as its much easier to understand...I think everyone should make a copy for further reference...Fisher referring back and forth to the pusbutton method(number one) is confusing at best..Honestly easy as pie and a few bobs and you should be on your way....Remember accurate ground balancing adds to depth and stability....

I'll second that, Dan. I made a copy, and carry it with my CZ-70Pro, even though, I don't really need it anymore. I put mine in one of those clearview sleeves, folded it in half, and carry it in my detector case with my CZ-70Pro. And definitely agree, that FISHER should make arrangements to copyright Mike's Instruction Sheet, and install it in their CZ Owners Manuals. HH
