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!

I will leave this question  to BW to respond to except to say it is NOT a ML patent! BW seems to think from field testing that his new GB method is superior to his patented method which is why he has adopted it.Its taken many ,many months and  hundreds of hours of unpaid work to get the new timings right!

 The question that remains to be resolved is does BW lodge a new patent application or reveal all here  as a free and open source project.Not an easy one to answer.

 At least all of this puts paid to all the lies on 1/2 wits and other forums that some how ML have killed  off or prohibited any discussion  or ongoing [email protected] on the QED!

In 1968, Eric Foster published a paper that disclosed the use of an integrator with a suitable time constant to create a null summation of samples to cancel long TC Earth and Static Magnetic Fields in a Pulse Induction metal detector. In the early 1980's he extended it to cancel the Log Linear signal from the ground.

The novel method disclosed here is a continuation of his pioneering work.

Performance:
Ground Cancelling - Excellent
Ground Variability Handling - Excellent
EF/SMF cancellation - Excellent
EMI Resistance - Excellent

0.08g nugget 10" mono coil 3"-4"
100mm*50mm*10mm AL block 18"mono coil 30"

So would you expect this new method to have  good sensitivity/ depth to a wide range of nugget sizes?

Correct. The "hole" created by the subtractive GB method is around the OZ nickel 20c and 50c pieces. These are nickel and don't equate to a similar sized/mass gold nugget. There are additional DEMPATS (Demodulation Patterns) that shift the hole so these coins then produce a good signal.

On the home page of the forum you recently said the QED was based on a lapsed patent could we be told what that patent is please ?

The alternating between long TX and short TX and the combining of the "TIME DOMAIN" samples from the long and short TX are covered by the lapsed Paltoglou patent.
The amplification of one of the "TIME DOMAIN" samples to create the null summation covered by the Poole patent. The 2 rapid short TX's create a "staircase"  voltage build up on the "+" integrator cap. The setting of equal width + and - "TIME DOMAIN" samples is covered by Eric Foster's 1968 paper.
The new method creates a "software" 2 channel "TIME DOMAIN" detector via separate digitisation of both the long and short TX.

Can you explain step by step how the new Gb method is  adjusted in the field.

As per the drawing, the delay to the long TX "TIME DOMAIN" sample is adjusted in 20ns increments.This is covered by my   "unchallenged" 2010101019.

can you explain how you have two channel digitisation when there is only one ADC in your circuit ... or is there two. Just curious :-)

The signal is digitised after the short TX (forms the short TC channel) and also after the long (forms the long TC channel).
When GB'd they will be exactly equal. When a target is presents it's TC will be apparent from the short vs long digitisation result.

Depending on the  Oz ground the "hole" is the same for all other detectors tested (it may shift with other timings) that use subtractive Gb methods.

Smooth timings shift the "hole" but at the expense of targets with longer Tc(a depth loss shocked of up to 30% on some from our own testing with nuggets!!)
The new QED timings do not need any "smooth " type timings and hence will not loose  up to to this 30% depth on targets with longer  Tc! Clap Hands  But will still detect the small nuggets and specimens!

 One of the real advantages of the new QED Gb method is its remarkable immunity to EMI compared to any other current PI detector when using  a mono coil. This results in a superior S/N on all sizes of conductive targets .It means that users does not have to continually waste time going through the ML re-tuning procedure or suffer the depth loss that results in having to use DD coil in cancel mode.

In some comparative testing  in a high EMI environment a  ML gpx in  any timing with a mono coil was almost unusable  regardless of how it was set up. At the same time the QED  was largely unaffected. happy face This makes a huge difference to the detection of small targets which were lost in the EMI noise with the GPX but easily heard with QED.and of course no more having to run any smooth timings like on the GPX and loose up to 30% depth on some targets Thumbs down CRY compared to normal timings! The other benefit on the new QED Gb method is that it has good depth and sensitivity to targets with a wide range of TC from relatively short to long and on some  from testing will match or beat any GPX! Hence ONE timing does it all! happy face
