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!

How about all attacks and criticism cease and we let the QED rise or fall on its merits and not on speculation and bagging from any who may have a vested interest in attacking a performance competitive product at a realistic price.

No worries, will look at putting one of the minelab kits on it, lol! Hasn't been released yet, but should work great. Nice light unit, internal battery, wireless speaker/phones....should be perfect.

Hi all,

I have not talked about the QED for obvious reasons but now can congratulate Howard on everything finally coming to fruition I have been involved in testing ETC. for a few years and can confirm it does find gold and is in my opinion equal to a GPX 5000 in most cases and better in some cases it is excellent with  Wi-Fi head phones I use TDK WR700 and they are plug and play and work a treat those who were brought  up with manual G.B will find it easy to G.B others will soon get the hang of it, the two most important controls are the Bias and the Volume settings but once you get the hang of it it is intuitive I have had it on ground that is around 70% iron content which was near impossible to ground balance with other detectors but was no problem with the QED,  Davent talk to Buggs about a speaker he should be able to put you in touch with a supplier as he has one that plugs straight in I have one here but I have only just returned from W.A so when I have unpacked I will find the box and give you its name and model number.

Regards, Ian. happy face

Point taken BW and maybe this posting had been forgotten about some time back.

Fair call. Let's get one thing straight though. I have no vested interest in attacking the QED. I do want relevant information. It doesn't matter to me if the QED costs $1 or $20,000 it must perform as stated to be of any practical use. If not it's just taking up valuable space and I've been there before with broken promises on cheaper machines that were going to be the next best thing. They weren't.  For me and likely many others the QED must offer an advantage to outlay the cash. If not I may as well buy 3 or 4 new coils and continue as normal.That is my vested interest in it.

The QED only has to be better that the ATX and the TDI because at around half the price including a quality coil it certainly has a place in the market.

Mylab is quite correct; only those present can provide info about the circumstances. But as this info has not been disseminated here, one can only speculate. It is my experience that the depleted underlying grey soils produce less ground noise than the surface "orange/red/brown" layer, and often far less ground noise. But I agree, sometimes it can surprise by producing some ground noise despite its benign appearance. The clay beneath can be noisier than the grey in between, but still less than the surface. Some of the signal from the clay seems to be because of salt quite often.

Out of interest on occasion I have tested VRM soil depth profile of earth exposed from being sliced open (by machinery), by deliberately setting a metal detector out-in-GB and waving it up and down over the layers of exposed soils. As expected the surface "orange/red/brown" layer reports strongest of all, and the signal typically gets weaker and weaker as one probes deeper and deeper, but can increase locally in clay zones, and eventually at substantial depth, the soil gives effectively no signal at all. Suggest others try this too.

Of course an exception to this is when water has deposited benign soil on top of mineralised soils, but this is usually obvious (e.g. bottom of gullies).

But this topic is about QED updates as others have pointed out, and I for one eagerly await its release!

The advantage of manual GB is that the setting gives feedback about ground mineralisation.
The higher the GB number, the more mineralised the ground the greater the chance of it containing gold.


First up "Happy New Year" to one and all.

This thread has certainly created a lot of views and replies as well on other forums.  

In the above quote from BW it appears the QED produces a numbered figure readout during its GB procedure.

Having those GB figures display on its LCD screen is an interesting feature and an advantage that I am not sure IF any other PI has and use also?

It is very useful to determine the "hotness" of the ground.
My standard backyard soil is mostly basalt. It GB's at 120.
I have a 19" diameter patch of Beggary Hill "soil" down the backyard that GB's at 130.
I went to Daisy Hill today in the VIC goldfields and it was also 130.
Each count represent 20nS of time when adjusting the position of the GB sample so from Basalt to Hot Goldfield ground requires a change of 200nS.
The QED also has other new innovations in addition to Dave Emery's patent pending Front End.
The Class D, 500KHz PWM audio provides a very sharp signal response despite the additional 4 stages of filtering to reduce EMI.

Hi Bugsy,

All the best for the New Year, With the GB being adjustable and making a difference did you include adjustment for damping of the coils to get the most out of them or is it a fixed setup now

Bugs, will a booster enhance the signal, or is it not nessasary?

The damping is fixed to suit  the typical coil 0.4 ohms / 300 uH.

No external/additional booster required, increasing the BIAS boosts the signal.

How does the bias actually work to boost the signal?

The VCA circuit (controls the signal volume) uses a small signal switching FET.
Such FET's have a Gate threshold voltage. The BIAS is used to raise the voltage so that when over a target it takes less signal strength to produce a good audible signal.

So could the bias be used to "dampen down" any ground responses from highly  mineralized and variable ground?

The bias can be reduced to cope with high EMI levels and anything else that produces a signal like moans from variable ground. Target detection signal will also be reduced.  Variable ground tends to produce a groan rather than a chirp from a metal target making it easy to discern the difference.

A lightning strike has taken out BW Internet and telephone. When he gets back online he will provide an update  re the QED  battery situation. I know it must be frustrating that this is holding up sales but it came about because BW was advised NOT to sell the QED with Li batteries because of the huge public liability risk for the dealer and BW and this necessitated a change of plan. If people want to use Li batteries then they can do so but they will have make the mods to the battery box themselves. Instructions on how to do this will be provided in the manual or an addendum to it.

Thats good news Bugs. Glad to hear the soldering iron was not stopped by the comms outage you had, not for long anyway.  smile

The $650 estimated price quoted by some flounders was made years ago, before it was redesigned / upgradded & the newest technology built into it. Includes a good coil valued at around $500 too. MADE (designed & built/assembled) in AUSTRALIA too, thats a good thing, worth "crowing" about.

 Pass the salt & pepper their way wouldya Reg?  

If you have your own coil & want just the box & stem then its only $1200 *   excited

What else can you get for that money??? (quoting YF)

 happy face

* PS: That's COMMERCIAL REALITY ..... but without the GOLD TAX!!
