I'm the first to admit I'm not great at finding faint signals in a threshold, I guess that's what excited me about the QED.  I can run it silent only making sound when there is a target like my Gold Monster.

But like Northeast said, that could just be that you have it tuned to the point that those sounds aren't breaking through the threshold, & you are missing them because of running a "silent" threshold. I feel very uncomfortable running no threshold. The Gold Monster made me very uncomfortable, being so use to having a background hum to compare any variation in it that signaled a target response. As we know, any hiccup in that threshold has been caused for a reason & needs investigating. That is where the importance of getting a smooth even threshold within what you are comfortable with is so important. Some can handle a ratty threshold, caused by ground noise & having the detector running hot, & still recognise a target response in the background comotion. I am now one of those, but it didn't happen overnight. Depends on your head space & your own mental ground balance :laugh:. Personally I think you need to run a threshold. It gives you a background canvas to work with in regards to any fluctuations. Does that make sense? Probably not:rolleyes: Time out in the field "fiddling" will get you to the Zen point.?

Yes, it makes sense to me. I love the idea of running a detector with no threshold, BUT my experience has shown me that faint variations in an audible threshold can be very important…so much depends on the area, the EMI, the mineralization and the settings one is using. I always run some level of threshold.

Time will tell if I need to run it with a threshold, the default setting is no threshold.  Just a few button presses and I have a threshold and it's easy to get it nice and smooth as it is so resistant to EMI.   What I've found so far like the Gold Monster even though it's silent if there is a tiny target on the edge of detection you get a little bit of a crackle noise.  I think good quality audio is vital on the QED as these little faint crackles are important to hear.  Headphones are probably best but I have an allergy to them so I'll be running my speaker setup ?

It's nice to see a civil discussion on the QED. I had trouble finding one of them when I was researching if I should get one. ?

I guess that with a lot of us that are so use to running a threshold old habits die hard. The theory & concept of running a threshold as a comparison point on detector noise, ground noise, & signal noise are just too strong to run silent at the risk of missing something. It is all a fine balance to get that right tuning zen point. Again, we are so lucky with our insanely mild ground. At the end of the day it is what each individual is happy & confident & comfortable with. So for you if it is no threshold & that helps your mental ground balance then that has its own merits. I'm late for work now. :rolleyes:

 Value and enjoyment is important. If you bought a Gpz the need to justify the price might ruin the fun!  

As I have progressed in my nugget hunting endeavors my detectors progressed too.

My first nugget was found with the original gold bug which cost 400 bucks, more or less...several detectors And thirty years later I run a gpz, I loved them all.

 I think you are wise to only focus on what you want and need...opposing opinions be damned!

What does this QED cost out of curiosity? I checked their page out but didnt see a price. I didnt know they were for sale to the general public now, stopped paying attention to them a while back with all the quibbling regarding them.

Some threshold is usually a good idea, the only time I run zero or close to zero is in heavy salt conditions. I probably run my threshold lower than any fairly experienced person I've ever met in the field though and I do ok still. In my mind the perfect detector has no threshold, it only sounds off on a piece of gold, no emi or ground noise. So in the future hopefully we do have zero threshold detectors.

Here is the QED for sale, its a package deal with the 11" coil, this coil is meant to be very good on the QED from what I have read.


So about $1280 USD for the package including the coil.  I didn't get that as I didn't want the coil.

I agree Jason, I think the ultimate is a silent detector that just sounds off on a target but has the power to reveal targets as well as a threshold would be great.

Interesting, thanks. That is a more reasonable price than I expected. Will be watching your reports on it.

Would be great to finally see an at least somewhat affordable detector that could compete with the GPX series if not exceed them. Both for new guys entering and that also looks like a nice lightweight prospecting machine for exploration if it can keep up, wonder if it gets nose heavy running bigger coils though?

Take the gold you have found and any other objects you like and make your own test garden.  

No detector sees everything either at depth or because of mass and sometimes size and shape.

Tell us what the QED sees easily and what it doesn't.

Since a few people have breached the subject: 

I talked to a gentleman earlier in the year that was running the QED in Cal-Nevada grounds - he stated that in low mineral ground he thought the detector easily kept pace with the GPX for depth and SDC for sensitivity, with a bonus being the lightweight where he could cover ground quickly. He also said that the more mineralized the ground became, the less this was true, with high mineralization making it no more effective than the SD series, and some severe ground crippling it beyond use.

That's one users review stateside so take it for what you feel it's worth. I know if I were in an area with mild to fair ground, like Simon, I would certainly take a look at simply from a weight and ground coverage perspective. Everyone wants an easy-to-swing pulse machine instead of the existing tanks.

      Hello All

      My First major outing with the QED. I intend to write a review here after ever major outing with the QED, until I understand the detector. This also posted in AEGPF. This is my first PI detector. Price, Capabilities and Aussie made were the driving factors to buying this machine.

      I went to Warwick GPA for two days. Two purposes for the trip one to recon as much of the all GPAs as possible and two to test my new QED. Recon was to look for potential Dry wash locations. That a different story.
      I found all the trash left in the GPA. Bullets, horse shoes, rusting tin, slug gun pellets. Nothing very deep though, all at only a few centimeters. This concerned me so I buried a five cent piece at 20cm on its edge to make it as small a target as possible. Picked this up no problems at all. Full repeatable target. So I am hoping I just didnt walk over any deep targets

      I took an XP ORX and my QED

      QED got a good 18hrs of use over the two days and used my ORX on some of the same ground: I found it interesting on how the VLF reacted compared to the QED. ( Not Direct comparison test)

      My QED setup is as follows:
      QED PLII with Detech Shaft
      11" Detech Ultra sensing
      Quest WIFI to a set of (Apple ipod earplugs ) I am going to buy a good set
      Warwick I found has a great difference in minerals across the area. So I had to make sure I basically reset the QED every time I changed location

      Quest WIFI - Worked very well. Battery lasts for 24hrs, just as well as I forgot to turn it off most of the time. Had receiver in my top pocket so my earplugs never got in my way. Forgot I still had them in a couple of times Overall very happy with this audio setup

      Detech shaft - Excellent

      11" Detech Ultra sensing coil - Being my first coil other than HF on ORX - I a had to get use to it sounding hollow while passing it over the ground. Being hollow cuts down on weight I suppose which is good.

      I had to Factory Reset at every new spot I detected, as trying to adjust from the previous location was to hard. So in the end I just factory reset when I turned in on at a new location and went through the setup process. Working through the settings starting at 2, then 1,3,4,5

      I talk about each setting in the order I used in my setup process

      THS-B - Setup range was 49 to 59 so around 54 was mid point. I used it at mid the entire time so I would received an even tone for Small and Large targets

      MGB - Setting ranged from 170 to 210. I very quickly got use to checking MGB on the Fly. I did find myself trying to balance in the wrong direction quite a a lot, this just meant spending time cycling back the other way to get correct MGB ( Silence in the Ear Plugs). MGB is achieved on the down motion of the coil, but I was receiving a tone on the up motion as well. Once I got use to this I adjusted the MGB until neither tone could be heard. Once MGB was achieved the detector was silent.

      THS-A - This setting initially confused me a bit, as to me it I felt it wasn't really doing anything, after watch the training video over and over and reading some more I understood its relationship to THS-B. This how I used it - (This may be totally wrong so I will need some feedback here). Once I achieved ground balance I would adjust THS-A up until I could just here a tone being produced I would then turn it down until the tone was only just audible. I took this as being the sweet spot for THS-A. Around 50 all over the GPA

      Gain - Adjusting Gain up above 2 produced an unstable response from the QED so 2 was the max setting for most of the trip. Adjusting Gain up also effected the tone produced by THS-A. I put the Gain up and went back to THS-A to try and adjust the tone out. This had no effect. So reset THS-A and lowered Gain to make detector stable

      Mode - This setting is coil and ground specific to achieve a balance. I found that 3-4 was good for all areas I detected. Anything higher or lower made the detector unstable

      After going through this setup( Only took a minute or two). QED was basically silent except for the very low tone that I could only just here from THS-A. While swinging I kept the coil in contact with the ground. I did not receive any coil to ground contact noise. At times I had to check that the detector was still on by passing it near my boot to get a target response ( steel in boots) The silence surprised me, but was excellent as I didn't have to have continual noise in my ears detecting

      In patches this happened. I would get single tones from the detector both high or low, swing back past the spot of the tone, nothing. If I started to get these tones, I sometimes stopped moving the detector and listen, random tones still produced (EMI ground mineral) ? I also came across patches that produced multiple random tones. For example a patch 1m square where the detector was silent all around it, but just produced random tones all over the 1m Square. Nothing repeatable in one spot. I dug this out of curiosity, after removing a couple of cm all tone was gone and no target could be found or single disappeared. So eventually I just ignored this type of signal response putting it down to soil type\minerals. I also had tones that produced like a wobbly type noise that was over one spot that sometimes came and went. When dug target disappeared or I found I just spread the target noise over a wider area.

      When target was found the tone was easy to recognize and repeatable over the one spot

      Please feel free to give me feedback on my setup. I dont know if I am reducing the small target detection or loosing depth

      This was my first experience with the QED. Overall I am very happy and excited with my purchase. All I need to do is walk over some yellow and find it. I think my next move is to setup a test patch somewhere. Lead sinkers from sub gram and up

      Great news for all the QED owners, it was announced today the QED has been updated with new ground balance firmware along with support for DD and CC coils like the new Concentric coils from Detech that have just been released.
      Here is the official announcement from Howard, the God of the QED.
      Interfacion Pty Ltd is pleased to announce that the QED has been modified to allow the use of DD (double D) and CC (Concentric Coplanar) coils. This change involves a simple change to the electronics within the control box.
      The firmware has also been upgraded to include a further improved Ground Balance.
      All detectors being delivered to new customers from Monday 5th August 2019 will already have the above upgrades included.
      As a show of commitment to all QED owners, the hardware modification to allow use of the DD and CC coils will be provided at no cost.
      Of course and as per the QED warranty, the firmware update is provided free of charge, except for P&H.
      Any QED owner who plans to attend the Laanecoorie Bash is encouraged to bring their detector along and have it upgraded at no cost.
      Awesome news, I'll be sending mine off ASAP. 
      You can find out more about the QED on their official website here http://www.qedmetaldetectors.com.au/

      I consider myself to be extremely fortunate due to the fact that the entire age of modern metal detecting has taken place over the course of my lifetime. I was too young in the 60's to be one of the many famous names that were there first on the ground with these new toys that go beep. That's good though for me as most of them are gone now and I'm still here. I got my first detector at the true dawn of the modern detecting age when I got my White's Coinmaster 4 in 1972. It was one of the first of the new "TR" machines that were the starting point for what most of us use today. Mine was as basic as a detector gets, no ground balance existed yet or discrimination. Just a couple inches depth and a beep, dig it up. So I have been involved in detecting now for 47 years. I started my business while in high school in 1976, and have been involved in metal detecting pretty much daily ever since.
      Anyone who followed my online presence starting in 1998 may see a pattern. I have been involved in some top end machines, some VLF, but basically almost every ground balancing PI made has been in my hands at some point. I had a vision in my mind based on my background in computers that told me what was possible and where we were headed.
      I was particularly incensed when an upstart company from Australia showed up the industry leaders at the time with the world's most powerful gold detecting PI machines. All the more so when I heard White's had a shot at it and passed. I made it my mission to jump on and foster anything that came along that might compete, and so I was involved with the Garrett Infinium, the first U.S. ground balancing PI. I had a lot to do with White's finally producing the TDI.
      Yet the fact is nobody ever seriously took Minelab on, and finally they won me over because they delivered when the rest just milked us. Minelab has been the sole company at the forefront of this technology since the SD2000 was introduced.
      All this time I have wanted two things. A vision in my mind of what a VLF could be. And a similar vision regarding a PI. Both those visions basically revolved around something a normal person could use both as regards ergonomics and price, two areas we kept getting bent over on for 20 years.
      Long story short I am grateful to Minelab for allowing me to be involved in the machine that delivered on my first vision. The Minelab Equinox is the first machine ever that really can do any VLF metal detecting task and do it well. In any one area it may not be "the best" but no one machine delivers across the board like the Equinox. My VLF quest is over. I will use an Equinox as my primary unit until a detector comes along, probably a Minelab, that does what it does but better. No more VLF buy and try for me. Yay!
      In 2017 I laid out my vision for the PI I wanted. The price was kind of a set the bar high (with a low price) thing so there is a little wiggle room there. But not a lot... the machine price should be something most people can stomach. As far as I am concerned the GPX 4500 sets the standard at $2699 both for performance and price. The TDI wins on ergonomics but loses too much in performance for me. All I really wanted was a GPX performance in an ergonomic package, and we all know it can be done. That is what is so frustrating. It's one thing to introduce new tech but all I want is proven tech packaged right. Garrett has really been a disappointment not putting the ATX in a light box. They can do it but so far have refused. I would have been satisfied with that.
      Right now I am calling the Australian made QED as being the default winner of my challenge. The rough edges have been smoothed out, and it's got the ergonomics, coil selection, and price all right. I am not going to argue with anyone over performance. Based on what I know it's good enough for me to go find gold and easily beats the TDI and is competitive with GPX. Good enough for me and good job boys. The only niggle is no FCC approval for U.S. sales, no U.S. dealers or service. But by end of 2020 if there is nothing better I will have one anyway.
      But we have the Fisher Impulse AQ on the verge and a dry land prospecting version promised. I would be crazy not to wait and see what develops there. I sold my GPZ for many reasons, mostly because I was not going to be detecting much this year, but I resolved when I sold it I would wait until my vision appeared. I knew it was close. I decided I can have fun enough with Equinox until that happens.
      Put as simply as possible I want a reasonably powerful PI packaged like a good VLF that most of us can afford. Something that can get in and out of a small backpack with an hour of labor being involved.
      So I am tossing down the gauntlet. I have my magic VLF and am looking for a mate for it. Right now QED and Impulse are in the running. And it's up to Minelab, Nokta/Makro, and sure, let's toss Garrett and White's in there also. It's time to deliver as by the end of 2020 I am getting one. I prefer in the spring but if something is one the radar I may wait. By 2021 I will be using something that finally fulfills what this high school kid from Alaska has known would happen someday. And I got to be there and see it all from start to finish. As I said... a very fortunate soul!

      The QED had what I call quite a significant upgrade in August, I was very eager to get this upgrade so I sent mine across to OZ straight away.   I was pretty impressed with the upgrade.
      The upgrade included a new method for the detector to ground balance which makes it handle variable ground better and an extended ground balance range which used to be 1 to 200 now it's 1 to 300. 
      For me this allowed me to run in beach mode in a lot of places around here.  Beach mode is essentially no ground balance like the coin and relic timing on the GPX.  I'm not quite sure how this ground balance update did this as I'm turning ground balance off by going into Mode 11 so I guess the update changes more under the hood than I understand.
      The other update allowed it to accept DD and Concentric coils as earlier model QED's only accepted Mono's.  I've tried a DD out on my QED now, I was surprised how quiet it ran, the QED is already great with EMI except in the most extreme cases but then the DD fixes that up.  There was a bit of confusion early on after the update about the Concentric's not working after the update but it appears that was only on some very early model QED's that needed a minor hardware modification to resolve it (desoldering a bridged join I believe) and that's been ironed out now.
      Anyway, now with this new update comes a new manual, so for existing QED users or those who just like to read about detectors and how they operate the manual is available here
      I heard a latest model QED has now been used in USA and the modifications to it that were required to match the EMI immunity that we in NZ/OZ benefit from worked a treat, the QED was able to run right near power lines there too.  The US power network runs on 120v as you know, in NZ and OZ we run on 240v so I guess something needed changed in the QED to allow for this difference.
      There are two shaft options now too

      The new compact, super light PI from Ballarat, Australia. This machine uses any Minelab PI compatible mono coil and is dynamite on small as well as larger gold. It is almost totally unaffected by  EMI enabling it to be used near or practically beneath power lines. All hand built, on a limited production scale, this little beauty is creating great interest in Australia, where it can handle the highly mineralized soils.

    • By Steve Herschbach
      I wonder how it would do on Florida beaches? Very light weight, super hot on small stuff, can use Minelab compatible coils.
