Seeing we are talking about reviews it prompted me to finally do my review of the QED on DP forums detector reviews database, I've held off on this for quite a while as I wanted to make sure I was comfortable enough with my opinion on the QED to give a legitimate and fair review.  For those interested you can read it here :

G’day Phrunt,

A well thought out review.

After I do my initial setup as talked about above I off camera apply all the advice I have received on this AEGPF and Detector Prospector

So the end setup was reached by

1. Factory Reset
2. MGB - Changed from default to 220 as a start point - Not balance yet though.
3. Mode - Set to 3
4. THS-B - Set to Null
5.THS-A - Set to highest I can get until I hear a soft tone
6. Gain - Set to 6
7. Adjust THS-B and THS-A to stop noise created by Gain at 6
8. Lower THS-B couple clicks below Null for enhance small target response.

I think this setup still requires some tuning. Time in the field swinging is required. I need to carry a test piece of lead to confirm my setup at each location.

Thanks Dave for the video as seeing can also explain things much better than words.

Also good to see Northeast upload some videos as well of his setup on another forum.

And Northeast said "As with many detectors personal preference is key"

Definitely given me things to try after viewing.

Those little occasional blips you're hearing in your video are likely EMI Dave, in my experience if the QED does those blips in a location my GPX would sound like a mixture of a UFO crossed with an Ambulance.

Hi Dave,
I have noticed that when you setting THS-B you only gone up till you have achieved a decent volume and going down with the setting you stopped at the quietest reading at 44 you should have gone further down till you achieved the same volume as well then calculate the mid point (neutral).
My feeling is that your neutral will end up around 44 plus minus 2. I have the same set up with the Detech coil and I have no problem running at gain 6 unless the ground is getting bad. Please have look at the videos on the QED detector web site they are very good to start with, if you haven't already done so .
I hope this will help.

As I said being able to view a video can enable a better understanding than written words as I expect those Video Instruction (VI) clips can help as displayed on the QED website.

Therefore the videos that Phrunt, Dave63 & Northeast have produced so far has allowed a visual understanding of their QED setups for other QED owners to gain further knowledge of different ways to operate and detect with the QED.

Also videos captured of setup & settings with the QED out on the goldfields would be of further interest and help for others as well along with the variety of coils that would be used.

As another new user, I am a bit confused by Dave’s experience with an increase in mode making stability worse. It has been my experience that a mode increase settles  the detector and makes it more stable when other settings are adjusted for the increase. Like Simon, the soil here on the east coast of of the USA is benign when compared to the conditions in Australia and that may be the difference. I just spent a couple of weeks in conditions considerably worse than the coast and used a 14 inch elite coil for the first time and found it necessary to increase the mode as would be expected due to size and to quiet the coil. Am I confused about the effects of a mode  increase (timing slow down)?

From memory mode 1 is 7.5 usec timing and it goes up .5 per mode number.  I could be wrong on the start number but I'm pretty sure it was 7.5

That makes sense as I understand PI technology, so going up in mode should (and does on my detector) quiet noise if other settings are properly adjusted.

Thats how it is here in Nth East Vic reasonably noisy ground.

G'Day All

Today I went and found an old mine. No Luck today

Todays Settings

MGB: 214
THS-B 48
THS-A 001
Gain 6
Mode 3

THS-A at 001 was the point where the detector was at its most stable with gain on 6. QED still was most stable at Gain of 2

Cheers
Still a lot of intermittent noise, basically all the time

Dave63 from what I know the “QED PL2 video” that was uploaded to the QED Metal Detectors YouTube site    was taken in the Warwick GPA and may also be of further assistance to you in regards to settings as it goes to show even with only a GAIN at 1, the others settings THS-B and THS-A can be used for success.

Also the “TESTING QED with 11 Mono Coil” video that had been uploaded to the QED Metal Detectors YouTube site displays results while testing over buried nuggets using different settings.

As MODE 6 was used in both videos then if you refer to Goldman’s QED Delay figures in his table of delay times for MODE (pre-upgrade) and MODE (post-upgrade) then MODE 5 would be similar using the latest upgrade.

No doubt the GAIN does lift a target response but can at times also be problematic.

Dave, THS-A @001 looks like MGB before you enter it.

G'Day All

Quick update to my Setup problems. After an on the phone lesson with Goldman. I sent my box back for testing.

Bench test found my SMR was not filtering EMI at factory Default of 107 so been changed to 109.

Bonus for the trip was the latest Firmware updated which has made changes to GB. Box in on the way back to me now.
 
This is one of the great advantages of the QED EXCELLENT customer service, with fast turnaround on diagnostics. LOVE your work !

Any of the other major detectors and I would not have seen my detector for weeks !

G'Day All

I got my QED back yesterday, so today I took it out for a test, before hitting the Gold Fields. My QED required a custom tune to filter EMI. My default setting for SMR is now 109 where all other QED has a default of 107. I also got the latest Firmware update that lows the required number for GB and negates the need to GB after a Mode change.

I rang Brian who as always was more than willing to pass on as much info as he could. He explained the reason for the firmware update. As spoken about by other QED Users with the previous Firmware 220 or above was required to GB. Brian did not like the fact that the GB number was so close to Maximum. So the new Firmware put GB lower.

So my settings before the tune up at the same location: Sadie Coil

GB : 225
THS-B: 55
THS-A: 30
Gain: No higher than 2 before detector became unstable
Mode: 1
SMR: 107

After Tune-up & Firmware: Sadie Coil

GB: 110
THS-B: 52
THS-A 65
Gain: Depended on THS-A setting. THS-A at default Gain of 10 no problems. THS-A at 65 Gain 6 no problems which is optimum for depth.
Mode: 1
SMR : Custom Default of 109

My QED is now firing on all cylinders. On my best settings I was getting approx. 700mm above a bottle top on the surface of the ground.

Again my thanks to Brian and Howard for their prompt diagnosis and tuneup. NO better customer service anywhere.

Cheers
