Some software and hardware updates now available for the QED.More  QED firmware updates (inc Auto GB  option) just announced here. New  QED hardware updates/options and pictures will be posted  first here  as they become available.

Another satisfied QED user! QED user report for 9 days detecting! User loves it, found it easy to use,found gold with it and he prefers it to his 5000! Also a report on a QED used at the beach for coin shooting.QED users reporting in with their multi ounce gold finds with the QED!
From  another QED user today:"Been out and about today testing and comparing against other machines etc in ground that has been horrible in the past.Bround balancing Ive found very simple and easy.'m using the Nokia booster but need a little more sound/threshold.Otherwise no complaints from me, very impressed."
and :"My QED with the 8” commander on it, out performed my SDC Got bits that don't register on my scales SDC has since been sold"
"My QED is terrific. Lightweight, very sensitive and screams at me when it hits any target. The Detect shaft and the 11" ultra sensing coil is a top quality fitout. I attached an external speaker which added under 200gms of weight in total and still remains very well balanced so i never feel fatigued after many hours of swinging."

Stinky  Pete :http://www.detech-metaldetectorsaustralia.com.au/  and Goldsearch Dunolly are the  Australian distributors for the QED.
This is the only forum where you can talk directly with the designer/ manufacturer of the QED and  also some very experienced QED users.
Jrbeatty and Reg Wilson  and  Yellowfin  (or Doug here for that matter!)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! The ONLY people deriving  an income from the QED(other than finding good gold) are the 2 approved retailers and Bugwhiskers! The ONLY investor in the QED is Bugwhiskers!
I have never met Jrbeatty or Reg Wilson at Howards house or ANY other location!

I'm currently working on the DOD configuration, which requires much much more calculations. Unfortunately, the hotspot region (max. sensitivity) is non-linear and I have to find the max. response for a given depth. So I can't simply sweep the target in the vertical position only. That's the reason, why this coil causes so much work.

The sketch is showing the problem. Please be patient.

To be continued..

Above I have copied what Aziz said way back in Reply #12 on: Monday December 19 2011

Since the release of a DOD coil for the GPZ I have wondered what its Magnetic Field would look like so I am disappointed that Aziz did not get to complete this DOD diagram before he left this forum as many of his previous colourful diagrams he produced for other coil types in the past gave a informative picture of a coil magnetic field.

If you ever get to read this Aziz I for one would be like to see if you could complete your DOD diagram using your Magnetic Field Calculator & Coil Analyser program.

If not here maybe on Geotech.
