QED coming soon!
Goldsearch Australia has been appointed the Australian Distributor for the QED.Check their website after  Wed 7th Dec 2016.
Global temperature goes from heat record to heat record, yet the sun is at its dimmest for half a century.
What is empirical  evidence?
Empirical evidence is information acquired by observation or experimentation. This data is recorded and analyzed by scientists and is a central process as part of the scientific method. Why is everything posted on climate by Inhere always horseshit?
Poor old  Inhere on finders still does not know the difference between weather and climate!The silly old goat seems to think because some places have recently had very cold weather that this brings into question  AGW!  Only right wing rabble rubbish climate deniers like horseshit Inhere don't  seem to understand  that AGW will mean that some regions of the earth will become colder!
Why is  onehalfgram :1/2 wit always wrong  on the QED?

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.
