I just feel the Z is more stable if the auto GB or now semi-auto GB is allowed to collect its data without quick tracking

Mmmmmm, that's what I'm starting to wonder.   And if in a new location and I do quick track maybe the walk-and-sweep method might be more betterer...:unsure:

I have been advised that if someone breaks the ferrite ring, just put the pieces in a plastic bag and continue to use it – this will still work as it is the amount of ferrite material that is important, not the actual shape that is important.

This will be better than using another ferrite that is the incorrect material. Just because ferrite rings look the same, it doesn’t mean they will be suitable – they could actually degrade performance if the wrong material type is used.

From the Minelab Knowledge Base Article at http://www.minelab.com/__files/f/313856/4907-0942-1 Brochure, GPZ 7000 Software Upgrade No.2 EN.pdf

"A ‘dust iron’ toroid suitable for the HF frequency band (e.g.1–30MHz with an initial permeability of between 6 and 10) has been carefully selected. It is recommended to use this specific Minelab accessory, only. Alternate ferrites may significantly degrade ground balance quality."

As far as the ferrite and personal use, I do it myself at the start of new sessions because it is the best recommended operating practice. I can't swear I see differences between whether I use it or not, but I also do not usually see a need to fasten my seat belt every time I drive. Why bother today? Because maybe today is the day it will help!

As far as my ground goes and referring back to http://www.minelab.com/__files/f/313856/4907-0942-1 Brochure, GPZ 7000 Software Upgrade No.2 EN.pdf -

"Auto is the recommended setting and should give the best results for the majority of conditions"

Thanks, Steve;

I did just put the broked pieces in a plactic box...seemed to work...now I will have two...a whole and a lot of pieces.

2.5 years in the NT Norvic and about 8 months in Broome/Derby in the west. 

Reasonable schooling and a couple of family members are the only things keeping us in Vic. 

We nomad'd with the kids for a year. We all loved it but no stable friends was an issue for the kids.  My wife and I would live on the road if we had the chance.  

I haven't had a chance to catch up on reading any of the stuff you've put up SH but it looks like it'll keep me entertained for a bit. Thanks :wink:

(edit: read it now. That ground balancing in difficult conditions was good. I don't think I'd seen that one before.  Thanks again).

      Maybe a new thread if you have the time JP.  "How to target large, deep gold with the GPZ?"  Is it your conservative settings or something different again?  How does the audio differ, etc? 
      There are bits and pieces (linked below) that maybe all add up to an answer but if there are any other secrets you want to add JP,  I'll listen

       I have been painfully considering a purchase of a 7000.  Seeing the gold a friends 7000 is getting that seems to be out of reach of a 5000 is giving me reason for this consideration.  However with the areas I used to have access to that facilitates the use of the large coils are being lost due to development and I would have little or no areas to go that there would be a benefit to the large coils.  If Minelab would make a small coil like the 11 inch diameter that is stock with all the other models up to the 7000 it would justify a purchased.  I wonder if it’s the technology in the electronics that will not work with a small coil.

      Seeing some barely-used gpz 7000's coming across the auction block.  
      Weren't there early ones that had issues?
      If so how were these issues resolved?
      How can you tell if the unit on the auction block is not one of these?
      Having not owned one yet I'm a little behind and appreciate any feedback.

      I really enjoy using the LST, most of the time it is wearing the 5 X10 elliptical coil.  I've always wanted a small shooter coil so I picked up a NEL Snake coil, same size as the White's Goldmaster shooter coil.  Installed the Snake and 'whoa' the LST will not ground balance in All Metal mode.  Pumping the coil repeatedly ... down stroke nothing ... upstroke the coil sounds off loud.  I tried changing the ground conditions mode and found no significant change.  I put the LST in discriminate mode and the machine seems to work pretty normal, much the same as my Tesoro 5.75 concentric. Placed back in the AM mode, unable to ground balance, I tried sweeping a 5 grain pellet at 2'" then 1" and got no response. Needless to say, pinpoint didn't work either.  The coil looks pristine, the previous owner had about an hour run time on it on his Vaquero. He says it performed flawlessly on the Vaquero.  I emailed NEL just to see what kind of response I would get.  Response... none.   Perhaps I'll not get the NEL coil for my Sovereign I've been eyeing.  At this point I'm very disappointed.

      Hello Johnathan the GPZ 7000 has been out for a while now, is there any plans to do a DVD. I could see how a soft ware upgrade could potentially make it harder to give any advice on settings as upgrades come along. Or is the whole thing a big head ache.
