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!

Hmmm....doesn`t ring my bell, it can only handle a dual supply of 2.75 volts.The OPA2140 is a better choice i think,it can handle a dual supply of 18 volts and still manage some impressive spec`s .
