Title: QED - Best small coil for $
Post by: Goldman on Tuesday February 5 2019 14:45:04 AEDT PM
Hi everyone,
If you were to spend your hard earned on a small coil for the QED, which coil would you choose. The contenders would have to be the Sadie, 8” commander or perhaps the new 9” elite.
Or are there any other contenders.
Obviously one can’t buy every coil out there, so I’m looking for your experience in regards to the above question.

Cheers Goldman

for all small gold i use the 8" commander coil highly recommend  ::10 ::

I agree with D777 as my 8" Commander works a treat on my QED.

I ended up selling my Sadie 8"x 6" coil as it appeared for me to be too sensitive to high mineralised ground with my GPX 5000 although since using the QED it has been capable of handling very high mineralised ground very well therefore I would expect the QED to handle the Sadie even better than my 5000 over such conditions.

As far as the 9"  Elite I have not read any reports yet with this coil on the QED although there has been good reports with its larger brothers 11" & 14" on the QED. Now if we are to believe what said in regards to the ELITE series that it improves depth & sensitivity when compared to a standard wound similar sized coil of up to an extra 30% then would we have to say then it would out gun my Commander 8" standard wound coil.

I suppose that is the decision you will have to make, maybe if you can get hold of a Commander 8" demo coil, an 9" Elite demo or even a Sadie 8"x 6" demo and run some comparison tests for yourself with your QED before you buy.

I would be interested in the results as no doubt other QED operators here as well.

Gary.

I already have the 11” elite and it is an extremely good coil on the QED, so having  coils from the same stable (elite) might be advantageous. I’m able to run the 11” in mode 3 nearly all the time, with either B neutral or low, or with A (very) high.

I have the 8" commander, and the 9" Elite. Both very good on the QED. Elite super sensitive, but brings up a lot of hotrocks, which can be sorted.

Actually with Reg mentioning Hot Rocks then as I recall now that was the major problem I had with the Sadie on my 5000.

Running the NF Evolution coils you will find that you cannot use mode 1 on the qed,  but using a NF Sadie coil you can run it in mode 1.
Mode 1 is good for fine gold, prickly gold and specimens.
I'm not sure how the 9" or the 11" elite coils,  if they can be run in mode 1, but being flat wound coils they might have the same problem.?

In a couple of days I hope to post some videos of the 12" * 4" capsule shaped coil made by IBGold. It's quite outstanding when it comes to its light weight and performance. How about 2"+ on a 0.033g (1/30th gram) nugget and 33" on a beer can without changing any settings. And the best part is you can move forward 9" on each swing allowing patches to be found much faster.

Impressive results BW.

In regards to my 8" Commander on the QED I have found Mode 1 too sensitive for me over extreme ground conditions.

Having a coil that can be used for a multi purpose (patch hunter,  small gold and larger gold) is a coil worth having, this is indeed a coil that provides great bang for the $.

mines too noisy over here in mode 1, but there are a few places ive been able too just use it in mode 1 though, mode 3 to 6 sometimes even 8, all depends how bad ground is. the hotter the ground the higher the mode is the way ive been using the qed. just sold my 4000 and purchased a second qed .... have the pl2 now and modded sd2000, and still change left over.  ::05::

Yep D777, what I have found where I detect.

Interesting you've got yourself a modified SD2000 which was my first PI.
I ended up getting it fully modified by Issy Jones in WA including his variable adjustable voltage regular enabling the detector to be fed with extra voltages....As well a VCO to adjust for additional frequencies..... Also additional GAIN adjustment for BALANCE 1 & BALANCE 11....And additional Ground Balance adjustment.

Mechanic who use to post here is the man who also knows the ins and outs of the SD2000.

Hi das, there were some good people on Finders , but some shocking rednecks and racists as well. At least here the posters are interested in detector development.
I actually have a bit of fun on Halfarse's forum, and although he is an uneducated and annoying little tool, and his forum is inundated with "fruitloops' there are some posters who are quite smart, and even Halfarse himself occasionally comes up with something interesting, although most of the time I just get the feeling that I would like to bash him.
PS Halfarse will no doubt monitor this post and probably post it on his forum.

As usual my addiction to testing and curiosity kicked in so set up the QED in the bedroom with it resting on the bed with the Commander 8" coil in the vertical position and my 3/4" diameter 36" long poly pipe measuring stick resting on the bed up against the bottom of the coil. With the QED set in FP settings I grabbed an empty 375ml XXXX GOLD aluminium beer can and waved it back and forth above my poly pipe measuring stick for a clear response out from the bottom of the coil at 20". I  ONLY then increased THS-A from its FP setting at 30 up to its maximum at 90 and received at clear response at 27". Goes to show how increasing THS-A does produce extra depth.

Okay D777 as my 2000 had BJs 4 position frequency switch added first before I sent it to Issy for further mods.

Actually ran some tests comparing different frequencies from the lowest settings on the VCO down at 0.890 Mhz up to a high at 3.158 Mhz.

From those tests the strangest thing to me was when comparing the results on my three large test targets the Alum. Block, 15oz Lead and 1150 gram copper piece and that was the deepest result on all three of the targets was using the 3.1 Mhz frequency setting rather than a lower frequency such at 1.2 Mhz that is supposed to produce the best depth on larger targets and higher frequencies more so a smaller targets.

Sorry Goldman as I have diverted away from the topic of your thread.

With running THS-A up near maximum, and it’s noisy, do a MGB, but if still noisy, then check that you are running THS-B at NULL (or close to it) as the THS-B useable band at or near max THS-A is very small.

My dads (RIP) 2000 is for sale, as it’s just sitting in my brothers shed not being used. Dad got it when they first came out and did get a lot of gold with it around dunolly and surrounds in the day.

I have used my brothers 8” commander in WA and around dunolly/Maryborough and in most cases was able to use mode 1. Some areas in WA were just to hot and variable for mode 1, so just increased mode to achieve stability - can’t remember now which mode was best.

Compared it with a SDC at dunolly, by cross checking each other targets, and the QED easily ‘found’ all of the SDC targets and vice versa, sadly all the targets were lead.

So that’s why I am asking for your collective experience as I had heard that the 9” elite was pretty good. Reg, will be very interested in your post re your settings testing of the 9” in the near future.

looks like il have to do some testing now mate  ::62::. the one i had years ago the rite frequency was perfect for smaller nuggs, it had the 4 potion switch.. found my first ever bit with it, this one has only got a 3 position switch, did you say yours had 4 positions.  ::62::

doug ::419::

Doug,
With THS-A set to near max or at max (90), then the useable THS-B band has decreased to perhaps 1 (no more than 2, and it would be noisy) either side of null.  Conversely, with low THS-A, then the useable THS-B is around 5-6 either side of null.
This is how the QED can be set up right on the edge of max performance, either looking for small stuff (biased very low) or looking for bigger stuff (high bias), or at neutral using THS-A (high) looking for any targets. The A in THS-A means ‘all targets’. Once the above is understood (with the appropriate Mode, and Gain), then you are well on your way to utilising the full potential of the QED.

BTW, near max (or max) THS-A, is another way of finding the THS-B null point, as the least noisy THS-B point is null.

Cheers Goldman

The gold I have found using Mode 1 with the 8" have been very, very small gold.
In fact I detected my smallest bit ever using it, and considered it deep v it's size, about 2" down.
Picked up a coin and a button at around (not Measured) 8" with it.

Will see if I can upload a picture of my smallest bit ever.

777,
The 2000 is original with the standard DD coil and the 18” ‘garbage can lid’ DD.
The headphones are a bit ratty; and of course no original battery.

I believe my brother is asking $1000.00

Post by: Reg Wilson on Thursday February 7 2019 17:36:16 AEDT PM
After testing the 9"Elite I can now say that it can be run in mode 1, however to do so the bias needs to be neutral, or very close to it, the gain must be wound right back, and the ground balance has to be spot on and changed at any variation. In mild ground it ran fairly well and super sensitive, but it 'talks' quite a bit. Increasing the mode made it a much more pleasant experience, and brought out less ground noise and false signals, with only very slight loss of sensitivity.
For hunting proven ground at a slow and careful pace the very low mode will make tiny deep targets jump out, but for 'skimming', the mode needs to go up as high as 8 to make it pleasant for faster ground coverage. This is a good coil for both slow and faster detecting as long as it is tuned for the task at hand.
I hope this has been of some help.

Thanks Reg, great report. Makes the 9” a buying proposition for an experienced QED operator.
Cheers Goldman

Gr8 pics thanks egixe4. I do think though that my tiny bit is tinier ::419::

That tiny bit was @ a measured 2" deep, my SDC could not get a signal over it
and was sold not long after.
This competition’s going in the wrong direction Howard, It’s the biggest bit we’re after  ::62::

After testing the 9"Elite I can now say that it can be run in mode 1, however to do so the bias needs to be neutral, or very close to it, the gain must be wound right back, and the ground balance has to be spot on and changed at any variation. In mild ground it ran fairly well and super sensitive, but it 'talks' quite a bit. Increasing the mode made it a much more pleasant experience, and brought out less ground noise and false signals, with only very slight loss of sensitivity.
For hunting proven ground at a slow and careful pace the very low mode will make tiny deep targets jump out, but for 'skimming', the mode needs to go up as high as 8 to make it pleasant for faster ground coverage. This is a good coil for both slow and faster detecting as long as it is tuned for the task at hand.
I hope this has been of some help.
Thanks Reg for your report.
Yes the flat wound coils are very sensitive and as you said,  the qed needs gb in variable ground.

You're right about getting bigger gold.

I had my sdc for 6 months before before I got rid of it and started getting heavier gold and deeper too.  ::62::

I hear there is a small party heading up North soon hoping for a "brag worthy" lump.

Ran some QED setting tests with my 8" Commander on 2 nuggets a 2 gram and 0.2 gram and the best result was THS-B 47, THS-A 60, GAIN 1 (being inside house) & MODE 15 so go figure that.

Therefore lowering THS-A to 60 from a higher THS-A setting allows for lower THS-B setting for extra sensitivity to both sized nuggets even with the MODE up at 15 which should help to tame cranky ground and then able to lift the GAIN further when out in the goldfield.

Gary.

Just speculation at this stage Howard

Forget flea poo gold. Use small 11" or 12" spiral as least size and still pick up fly speck and still go deeper

A pic of QED with Sadie coil finds over the past 2 days in the Smythesdale area.

Approximately 5.2 more hauls like this will see the QED finish paying for itself.

The Sadie and the QED is a great combo, good sized colour and yes much easier to pay off a QED than the other more expensive detectors.
