Just as well I subbed your youtube account then bugs. Will be very interested to see what the instructional video's are going to entail.

I noted on another forum that I am not a member off a claim that there is a 50+ person waiting list already at Goldsearch Australia. If that is factual then that is a bloody big vote of confidence in an untried product given that most will be cautious waiting on initial reports from Reg and early purchasers. Perhaps your word is worth more than you may believe yourself to the punters.

No doubt you will have up's and downs going forward but you have managed to do what others claimed you never would and brought the QED into the market... and isn't that something.

It's funny you know... the 7000 went for months before producing gold in acceptable numbers to the punters with lots of bitching and recriminations in the interim, people spitting the dummy and selling the Zeds within a few weeks of purchase, etc, and now the same knockers are demanding instant gratification without allowing the QED time to find it's feet. The whole thing is nearly comedic. Regardless of what is said or claimed in these early days the proof will be in the pudding and that will take time. Best of luck Bugs and I will be taking a keen interest in how the QED stacks up.... as will anyone that is looking for value for money  smile

BW is it possible to reduce the intensity of the fast noise spikes caused by  Sferics or lightning strikes (or indeed any other  sources of noise spikes) which may be mistaken for genuine target signals on the QED which has a fast  target  response?

Spurious high level EMI spikes can be minimised by clipping both via hardware and software. There is a section in the QED program that limits them but more will be done later when I am not married to the soldering station.

 one thing that is coming out from the testers is how vital it is to set up the QED  correctly whenever the coil is changed  to get peak performance. This must be explained and demonstrated in any videos and very clearly in the manual.

 BW do think the QED current drain with an 18" mono will be similar to a smaller coil?

 I think that from today's test results (thanks  Reg and  Wombat) that we can safely assume that the QED can detect larger targets at depth.So it would appear that the QED has the sensitivity to small gold comparable to the SDC and at the same time  will be able to detect deeper  nuggets if they are there. The  independent test results confirm earlier test results.

They will be very similar. Most aftermarket coils are 300uH and 0.4 ohms. What is not common is the speed of the coil ie it's resonant frequency and it can vary considerably. Tuning the detector to match the coil is what MODE (QED menu item #5) does.

Definately agree  - An sdc was a total fail on my part ironstone coated 1.5G chunk. but the QED got it close to Z but in hotter ground.

Yep totally agree Doug.

  

Without cherry picking, some analysis from the chart for the yet-to-be-formed "QED Marketing Dept"  

Comparing brands / models & giving the 243* aggregate score as 100% to the GPX 5000, the industry PI standard (some say), the following shows a comparison as a %

(* Using Aggregate Scores, all round score on small - large metal targets on ground in air tests)

Aggregate       Model             Score       Comments
Score*                              (rel. to GPX 5000)

157                2300                   64%      lower cost, easy to use standard for smaller gold
163                 ATX                    67%      US made PI standard, affordable

226         GPX 4500 (12” EVO)    93%      the PI target for GR & critics
232         GPZ 7000 (14”)           95%      "the disappointer" BUT may offer some advantages
241         QED (12” EVO)            99%   Aust made challenger: most affordable, lightweight & good performer
243         GPX 5000 (12” EVO)    100%    the industry PI performance standard, good all rounder

* on 17 metal (mostly standardised ie reproduceable) targets (v. small - large, gold, coin alloys & aluminium)


 happy face


  

Comparative test results gathered since April 2016.
The test distances are in Inches.
The AL* test pieces are all 3mm thick except the AL block.



Might be worth interested parties looking at the COMPARATIVE TEST RESULTS BUGs posted between the QED, 7000 & 5000 again in the light of what Reg & Wombat found. Its found on post #64, P4 I believe.  

Some doubters / scrutiniers may may still ask if the results posted earlier are consistent with what Reg & Wombat found. I suggest they are.  But I agree with YF that some of Wombats comments, which suggest annoyances (eg re-tuning after changing coils), are really an attribute with the QED.

Sounds like the 5.5 oz slug of lead at 22"  was invisible to to the 19" / GPZ because that was a hole in signal response

In summary, it sounds like the QED is (so far) living up to its long-touted & well-deserved reputation, here anyway.
The True Believers are Vindicated!

PS: Biggold, I don't post & haven't posted elsewhere, other than as Huego or (rarely as a) guest, for many years. There is simply no need to post anywhere else.

How do you know when you have the mode optimal for the coil you are using or conversely when the mode is not optimal for the particular coil you are using?

 I see that Reg has just posted on finders that the QED with an 18" elite mono could get the 5.5 oz lead target  at 22"with the coil  6" above the ground!
Reg is now going to use the QED as his primary prospecting tool   because of its  very light weight and ease of use. Both of these features will also be a boon to older weaklings like me and others! happy face

The depth test results hopefully will dispel any doubts about the QED's ability to find deep targets  and to do so without the huge depth losses(up to 40%  shocking) that  can result on some longer TC targets when using any of the smooth timings. The other good thing that Reg has found is the QED seems to run smoothest with large mono's.

Yep saw the 5.5 oz detected by a QED at 28" ... not bad eh? Furthermore.....

"The QED is built for prospectors, not just a modified military detector that is an ergonomic nightmare....

"The results from the test pad are .. an indication of the ability of the QED, and are certainly not claimed to be conclusive. .. I am now satisfied that those tests and others I have conducted are proof enough for me that I can now go prospecting in confidence using the QED".
 (24 Jan, by Reg Wilson, link-http://golddetecting.4umer.net/t24672p150-the-qed-and-me)

The testing continues, so these tentative conclusions from Reg should reassure many disbelievers of what one man (the designer / deveoper, Bugs) over some 10 years, even against the 'strong head winds' from critics & competitors, can achieve!!

The QED will find big gold too of course (eventually, when its there & there is a QED over it) as its performance with a 18" and 25” coil continues.

When a very small target has the best detection distance, this is the correct mode number for that coil.
