Hello all.

With the pending sale of the Z I am seriously looking at a QED as a lightweight PI that is at the price point for how much use I am likely to get out of my next 'gold' detector.

I am wondering if people would be happy to list the coils that they have actually used on a QED and how they felt about:

- its abilities in their given ground and what type of ground that was.

- issues or lack of with EMI.

- issues or lack of with ground balance.

- ergonomics/balance of the coil with weight, was a bungy required, etc.

I already have some particular coils in mind but would be interested to hear thoughts about others that I may not have considered. And hopefully this can also become a reference point for other QED users in the future.

Thanks, NE.

Favorite coils for QED. Small coils... Sadie, 8" Commander.
Medium coils...11" Elite, 14" Elite.
Large coils...18" Elite, 18" Detech, 25" Nuggetfinder, 38" John-hider Smith custom built coil.
I could probably cut this list down to the two most used coils which would be the 8" commander for tight or scrubby areas, and the 25" Nuggetfinder for open country.
The Elite coils are very good, but a little heavy, I guess due to more wire, and tend to be a bit noisier and less stable. The up side is that they are very sensitive and probably have a bit more punch than a bundle wound coil.
I have never had EMI problems with the QED and have found I can get very close to both buried cables and overhead power lines that sent my 7000 crazy.
Ground balance can at times be a bit finicky, but the areas that have given me trouble also caused problems with both my GPZ and GPX. I have actually found that having a manual ground balancing machine can be very handy in some problem areas, being able to eliminate many spurious signals.
Ergonomics.... Now this is where the QED really shines. It is super light and nicely balanced with almost any coil, not requiring a harness or bungy cord for all but the monster coil, for which I do use a bungy cord. You may require a bungy for the larger Elites, depending on your level of strength and fitness, but I do not use one for the 25" Nuggetfinder as it is surprisingly light.
I have been impressed right from the start as to how powerful this super compact detector is. Miniaturization at its best, with a battery life of about 8 hours, and rechargeable, of course.

Thanks Reg, perfect start thumbsup

The 25" Nugget Finder was the larger coil that interested me most.

I know that there is a lot of information about coils for the QED, wireless units, speaker systems, etc on this forum already but it is spread across several threads and 60 pages with a lot of other irrelevant info mixed in. I hope these more specific threads help others to refine their search.

Favourite coil was 11" Detech Ultra Mono. I found it a good allround coil that could match the 8" Commander mono for sensitivity. Found both my smallest & biggest bit with this coil on the QED & ran it in mode 3-4 mostly.
I only used the 8" Commander if detecting tighter areas.
The 8" Commander I had ran well but I couldn't replicate others who run them in mode 1 without a lot of ground noise/hot rocks. Was best for me at mode 3 >.
Also found the 16" Nugget Finder Advantage ran well on the QED. From most reports it appears that mid to large NFA coils all seem to run well on it.
No particular EMI issues with any specific coil just the norm when getting too close to other machines, when near some powerlines or approaching storms which occur with other detectors too.

Just to add further:
The Detech 11" Ultra Sensing Mono is one of two coils offered as part of the QED PL2 package
http://www.detech-metaldetectorsaustral … te-package
You could get that as a starting point & see what you think. No real loss if you decide you don't like it - sell it on eBay etc.
I read somewhere that your mate has a GPX5000 - if you do get a QED then hit your mate up for a lend of his coil collection & try them out on the QED. Best way to find what will suit you/your area IMO.

Just got some feedback on the 15x10 Detech coil that Stinky Pete is offering as an option on the QED package. A user reports that it is very stable over nasty ground and has surprising depth capabilities. He tested it against a friends QED, and said he was glad he took the 15x10 option.
Might have to see if I can borrow one to do a bit of testing.

Dave, your test with your machine may not have been positive, but I assure you my 4500 with a 17 x 11 Coiltek Elite in
Factory presets [and enhance] gave a definite "dig me" on the 4th target at the Coiltek test patch.
2oz @ 22".

And I assume you could still pick up the 1 & 3 grammers in the same settings? thumbsup

Must have been a different test patch, but with the above setting have picked up sub grammers @ 3"

Below is a screengrab of the original post, Target No.5 I have since found out is actually at 26"

all good mate , the coiltek test site Everybody gets fairly easy according to all video`s

this is in some Really Tough ground that even the 7000 with std coil cant get in difficult , but could get it with the 20"X coil

Redfin your 4th target is 2 oz at 20" , big difference to go another 3 inches in highly mineralised ground with charcoal

i made my test patch 1 inch deeper on the 1 and 3 gram targets
1 gram at 7 inches ( limit for the sdc )
3 gram at 10 inches
11 gram at 15 inches
3 oz at 19 inches ( way to easy )
2 oz at 23 inches . ( the tough one in my hot ground )

cheers dave

14 x 9 EVO runs pretty well on mode 7 around th b 43
th b 42 in better ground
th a 60

Commander 11" runs well on mode 7 also very similar settings

walking around i tend to stay in GB mode so i can just keep adjusting on the fly up or down 2 or 3

Have seen and used the test patch that 10pf is talking about on his property. Very heavily mineralised. As tough a ground that you will find. Lots of hot rock and some charcoal but the ground is natural, not made up ground. Old timer gold diggings there. Was an 18" xcoil used for test purposes. Cheers TG

Factory preset & go from there, tweak it to suit conditions, It'll tell ya if you're running too hot

ths a =50 or your null point, ths b = 70, mode = 4, gain = 5, leave all the rest as is, will find you 0.1 of a gram wth those settings.

Hi pinfire, your A abd B should be reversed mate. Easy done.

Try mode 3 with your gain around 5. If your gain wants to be around 1, try mode 4 with the gain hovering around 5. Do a ground balance after your reset. Once you have changed some settings, recheck GB. Check your null at THS-B. If chasing the smaller stuff, run your B 1 or 2 under null. Check your ground balance often as it can change often.

The Elite 9" is one of the coils that I use on the QED. I find it to be very good on small targets, and use it mainly for scrubby areas where larger coils are difficult to maneuver. I was told that this coil was very susceptible to hot rocks, but I have not found this to be much of a problem with the QED, although I have not tried it on my GPX.
My other small coil of choice is the Commander 8" which is very stable, and better at pinpointing with the coil edge, due I guess to being bundle wound.

The latest mod from Howard now sees the QED able to run DD coils. The new concentric coils should also work on QED although I am still waiting for my 18" Detech concentric to arrive to verify this.
I have over the last few days tested the QED with an 11" Commander DD coil which performed quite well. The DD allows the QED to run on higher gain settings and lower mode. Basically it does what DDs are supposed to do, allowing the user to detect changeable and mineralized ground with less need for constant re balancing and spurious noise. I tested it over ironstone and red clay surfaces where it behaved very smoothly and I rarely had to touch GB.
The other mod, DSM (Dynamic Spectrum Modulation) is a whole new GB system which has broadened the GB from 1 to 200 out to 1 to 300 giving a smoother more tolerant operation over all conditions, and makes for a more user friendly detector.
Both these updates are available free for all PL1 and PL2 QEDs, the only cost being postage to and from. The QED is now an even better PI detector.

Geez the QED runs so much smoother now with the upgrades done. Howard has done an impressive job once again.

Previously i was at Mode 3 with gain at 6 running the Minelab 11” mono. Im now at the lowest mode (1) and gain 10!

GB 249, THS-B 51, THS-A 60. Pitch nice and low at 15. Never touched GB since initial setup.

Hole not as deep as pick is in length as it was on the side of a mullock heap.

Aussiedigs I notice that you are now running in mode 1.
My understanding though is that the new updates basically remove the current modes 1 & 2 i.e. mode 3-4 on current version becomes mode 1 on the updated?
Not sure but do know that Howard has stated the new ground balance (DSM) starts at 8uS with 0.5uS per mode increments & there are less modes?
The current version modes start at around ~7uS I thought with a lower than <0.5uS incremental adjustment. Maybe someone could clarify this? Interesting as I always deemed modes 1 & 2 as pretty much unusable in most conditions.

Upping the gain to 10 is a good step. Wondering if this increase was in the same area you were running 6 previously? 6 was about the highest gain I could use with the current PL2 version in most cases.

My main area of interest though is the ability of the update to maintain a good GB as this was my biggest issue with the QED in some areas - constant GB adjustment & hot rocks. If it defeats this then it will be a winner!
Mullock heap areas generally speaking didn't cause many, or any, issues though & even my SDC would punch deep into them (one SDC hole was around ~700mm from memory on mullock). If someone is using the updates over some more mineralised & variable ground would be keen to hear your thoughts on the upgrades & in particular how the ground balance is over such ground in regards to both stability & ability to balance out hot rocks (+ stay balanced)!

Bare with me as im a tard when it comes to electronics!

My thinking was that if i could run the likes of an 11” mono in mode 1/gain 10 then the likes of a smaller coil could run in a lower mode if there was one. Apparently no as the ‘decay curve’ is as low as it can go.

I wasnt only swinging over mullock heaps. I spent more time over unworked ground yet i never readjusted the GB in the (short) time i was out there. GB at 249 out of 300 isnt what id call (at this stage) low on mineralisation.

If i hear of anymore explanations on this ill let you know.
