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(or secret deals or cash for comment or any other undisclosed benefits )in the QED other than using it to find gold which it is doing very successfully!
Over the overwhelming majority of typical Gf ground the QED GB works just fine! Another new user has used his QED over "fairly difficult ground around Waanyarra and Kooyoora areas  " and not reported any GB problems!
The so called QED GB problem is just  more fake news created by  some fake, delusional and dishonest imbecile cretins on 1/2 wits (who is a proven forum hacker and liar and  just dumb!) pox, liars and abomination and disgraceful atrocity sewer rats "forum" that have never used a QED! The QED has been used successfully to detect under 300k steel tower transmission lines(try that with a gp/gpx  with a mono coil!!!) so it  can handle bad  EMI! The QED will also run quite and stable in a household with electrical appliances running.Try that with a ML with a mono coil!!! "QED matches and and in most cases outperforms the SDC"  and will thrash it for depth on bigger gold. QED sales are still strong so if you are on the waiting list please be patient as BW is working 12 hours a day to try and reduce the waiting time.
Except for the USB port the prototype QED's are identical in EVERY respect to the production models and according to the designer  the production models may even be  better!
4umer makes another liar a moderator! How low can 4umer go!

NO to the best of my knowledge! The coils, the circuit, the firmware are  ALL settled! happy face

To me this latest setup of the Aux lithium battery box sounds a much safer way and similar to the GPX battery box setup although with it located beneath the armrest it will definitely act to counterbalance more effectively the weight of the coil. Even the GPZ has its lithium battery now under its armrest.

More eBay links.
It's important to charge the cells individually to maximise their life.

Bugwiskers, meeting up detecting friends on the QLD central coast, then travelling about the gold fields, but quite where we go detecting depends on the weather from day to day. We share a variety of detectors.
Be assured that I will not be detecting during the QLD summer afternoons!

With all the negative stuff written about the QED during its development then sabotage would be a worry now it being ready for release.

Precisely, and there is a long history of that.

The attached pic shows a quality  "Hammond" case that can hold 3 * quad LI Ion packs. It the cells are 3000mAH then it can have 18000 mAH. With an average current consumption of 450mA then detecting time between charges is a whopping 40 hours.
I have to obtain the sockets and make the PCB's. The addition of a double pole, double throw switch and a 3 pin socket would allow balanced charging without removing the cells.

Another eBay link.

  

At this price you could fill all sockets for $77.76

Unless you are really lucky and get a set of real Ultra Fire 3000 maH 18650 cells, treat anything that has the word Fire in the name with suspicion , there are tons of fakes around.

Yes, so I found out. That's why after 3 years they are still sitting in their wrapping.
They did serve to show how they fit in the case so at least they were of some use.

Aux box looks like a great solution,
Also seems to have enough room for a small external speaker as well for those that want one ??

Nice work

No room in box for speaker and probably too far away from ears also.
Ear buds are good and more bluetooth modules are appearing in the market that rid us of the tethering cable menace.

The AUX BOX needs to have 2 sockets, one for 8.4v charge and the other for 4.2v charge. A DPDT switch selects upper or lower battery in the series pairs.
When away from home, use a 8.4v car charger and when at home charge with 4.2v to balance the cells to maximise battery life.

If the above is not clear I will post a drawing.

The switched balance charge schematic.
Only 1 charger can be used at a time.

The new  patent pending front end of the QED does not work well with DD coils. Not sure of the reasons for this. However it works extremely well with mono coils of all sizes and as QED seems to handle mineralized ground very and so far is far less susceptible to EMI than other Pi detectors with mono coils i see no reason why anyone would want to use a DD coil.

I have been following this recent progress with great interest.
I have noted you test results with smaller coil and on face value appear impressive but l would like to ask how did the relarger coils perform eg: the 15 inch or new 19 inch as these are the coils l would be utilising.

When inground testing against other brands of detectors was there any gold that the other detectors located that the QED couldn't hear and vice versa. What were the deepest bits and on what size does the QED perform best on.
