I have a friend who called me today telling me his GPZ is very unstable, particularly after the recent rain in WA. ie. running noisy in all settings.
I advised him to do a reset all but he insisted that he has tried everything and still cannot get it stable.
Does not have the ferrite with him so this is not an option.
Is there anyone in Western Oz who has found a fix for the problem ???
If I remember correctly I think Davsgold was experiencing a similar thing in the early days of running the GPZ.

Cheers Bill asking on behalf of Tiboo Dave who is a member but not on the forum much.

Hi Vasili,

If your friend is having stability problems with a GPZ 7000 and you have tried all the remedies, ideas and suggestions on this forum and others, the only solution is to return it to Minelab for inspection, report and repair. You are not alone with this issue. Only now are 7000 owners starting to realise the 7000 has major Quality Control issues. WA is probably the worst ground in the world for a metal detector. Any weak point in design or manufacture will be exposed here in WA.

Send it back. I did. I sent mine back, and it was found to be a "dodgy connection,,,,(verbal report)". My 7000 should be back with me by tomorrow after which I shall be testing it once again in the WA Goldfields. For now, just send yours back to Minelab with a full description of the problem and a full list of the settings that you have been using.

Good luck and pls keep us informed about the resolution of your problems.

Hi ichi-ban. That's not good news about your detector and I hope it gets sorted out.
I am currently in Vic and have no problems with mine but David who is now in WA is having some issues.
He has found gold and is working with it at the moment but he said it is incredibly noisy and sometime almost unusable.
We both tested our machines here in Vic before he went away and all was ok. Not sure what to say but any suggestions for a remedy would be appreciated.
Keep us updated on how they fix your ichi-ban because this could affect us all at some stage. (hope not though)
cheers Bill

Yes I was experiencing very similar problems, the ferrite helps a lot, and without it, will be very difficult to get it to ground balance properly on a lot of the ground. Get him to get a ferrite sent to him it is what he will need, (provided there is no actual fault)

Once he can get the ferrite and get the machine ground balanced in auto tracking mode then switch to manual mode (old fixed) by using the user button option, this makes it easy to go between auto tracking and manual GB. I find using manual in the bad noisy hard to GB ground is best and just use the ferrite every now and again as the detector should not get a signal on the ferrite if it's GB is correct.

I hope your mate get it sorted out.

Hi Bill
check that all internal connectors are fastened tightly (slide the control box forward)
If that doesn't help, send it back to ML and they'll fix it. I had a very noisy unit that drove
me insane, thanks to a poor solder joint. Where was it manufactured again ML?
Now she's purring again like a kitten Smile.
cheers

ps- a big thanks to Coiltek that helped me out with one of their control boxes while I was
waiting for mine to come back...

Great, thanks for the advice Davsgold and bedrock.
I will text him this and hopefully can get it sorted. I will follow up and see what works for him.
He also has the GPX 5000 with him so he can do a comparison for us.
Cheers Bill
