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/ is the  Australian distributor 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 approved retailer 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!

Circuit Layout Techniques And Tips (Part I of VI)
by Bonnie C. Baker, Microchip Technology Inc.
The Art Of Laying Out Two-Layer Boards
In this highly competitive, battery-powered marketplace, cost objectives usually dictate that a designer use two-layer boards in the design. Although the multi-layer board (4-, 6-and 8-layers) allows the designer to build cleaner solutions in terms of size, noise and performance, financial pressures force the engineer to rethink layout strategies with the two-layer board in mind. In this article we discuss the use or misuse of auto-routing, the concept of current return paths with and without ground planes, and recommendations for component placement where two-layer boards are concerned.

The analogzone website seems to have died.

But you can find all six parts of the series from this great page. (There is other stuff there that might be of interest, too.)
