QED is here! ML have NOT stopped the QED!
Goldsearch Australia has been appointed the Australian Distributor for the QED. QED info on the Goldsearch website has been updated.
This is the only forum where you can talk directly with the designer/ manufacturer of the QED!
Jrbeatty and Reg Wilson  and  Yellowfin have NO vested  or pecuniary interests in the QED other than using it to find gold which it is doing very successfully!

Not too sure Doug, as I've never tested it.
The soil here is red with moisture in it most of the year and no signs of iron. I've even tried salt gold mode to no effect using a mono and DD coils.

If using the salt mode has no effect then we can probably discount conductive ground. The  soil red color  however does suggest a high Fe content.If the soil  has VRM iron maghemite then the 5000 should cope with it in smooth modes.Another possibility but rather uncommon are earth currents (telluric) which  do occur here in Vic due to some SWER power line earthing or  some underground cables or pipe lines. If these are the cause then they will produce random signals and noise which may appear to be that the detector won't GB. These telluric currents tend to follow the path of least resistance ie fractures or faults or some  kinds of bedrock.

There are only two gullies that this happens out of the whole area of that Goldfield. Now that you've mentioned earth currents,that rings a bell because the ground noises stayed the same when the settings were changed and I've tried them all.
So earth currents seems to be the likely problem.
Might have to get the ground tested as there's a lot of deep diggings there.

I got my speaker from e bay, so its probably all the batteries supplied with that speaker, changed mine out, no worries now, ta.

Total muck around in suburban Darwin, about 30 minutes.
I need to muck around with the bias a bit. I started at 50, and because my test piece was so small, was thinking I would need to drop it below 50, but found the opposite, and around 54-56 actually calmed the machine down. Mode I found 1 got a good response. 12" evo. That's it for now, I need to get out of town, Saturday and or Sunday. Very impressed so far. Oh, and I had to use my 7 yo daughters I pad headphones, $20 from woolies!

It would appear that the batch of Nokia speakers have been supplied with batteries that have a poor shelf life. I suggest buying some ALDI AAA NiMH. The Nokia speakers shutdown if the batteries are flat or if the input signal is too high. I have some that are 4 years old and still working well.

 Why did JP only report the  QED air test on a 5 cent coin and not other coins or more importantly gold nuggets? What is he trying to hide?

Another kind of ground that can be impossible to GB on is that caused by lightening strikes on some high  Fe soils.

One of the  people  here who  has tested a QED prototype had some ground  that he could not balance his ML on with a mono coil but could achieve GB with the QED.BW has a sample of this ground which reads on the QED 148 by far the highest  reading so far uncounted. The ground is about 70% iron and if you drop a magnet into it the magnet picks up virtually all the ground! When BW showed me this i was amazed!This ground is worse than even  BW Beggary hill Wedderburn test patch!!!!

Excellent!

Can someone check, if those hot Fe soil alone has some degree of magnetic properties too?
Mean, if dust or small parts of those soil stick to usual iron? Check to magnetite ore content.


I will see if i can get BW to try your test and perhaps take a picture of  some of it.

 I expect that their may well be some ground where the QED GB may struggle. Highly reactive ironstone margins of some WA salt lakes  might be one example although to my knowledge it has not been tested in these places. Highly reactive and conductive ground will cause problems to all detectors.

G'day Doug,
Yes there's ground like that here in nsw where my gpx 5000 will not ground balance or the sdc 2300. Even a DD struggles and goes out of balance. Would be nice to know if the QED will be able to GB?


Any idea of the nature of the mineralization?
