Title: QED User Experience\Review
Post by: Dave63 on Friday November 15 2019 16:26:30 AEDT PM
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 ) ::620:: 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

Thanks Dave- good report. I’m also a newby with the QED and I think my problems are thinking it through TOO much. Castlemaine tomorrow. Got to dumb myself down further!


Title: Re: QED User Experience\Review
Post by: Dave63 on Friday November 15 2019 17:23:06 AEDT PM
Just read the manual again taking into consideration what I just wrote. (Amazing how much clearer you thoughts are after you put them on paper\Interweb)
If I was advising myself I would say

With my setup process After setting THS-A I should have recheck THS-B. Leaving it at NULL produced even small and large target response, but Warwick is mainly small targets so, THS-B should have been set below NULL to enhance them. This would then change the tone given by THS-A, so I would now go back to THS-A and fine tune it to a comfortable level. Which also removes instability of response ::103::

Am I correct

MGB, Gain and Mode are easy to understand. The secret to the QED is understanding the relationship between THS-B, THS-A and coil size.  AhHa moment just had ::106::


Title: Re: QED User Experience\Review
Post by: Goldman on Friday November 15 2019 17:52:46 AEDT PM
Hi Dave63,

First thing to do is to absolutely know what your THS-B NULL is. 54 is a little high from my experience, however as each machine is slightly different and depending on prevailing conditions at the ‘factory’ during final post production setup, a NULL of 54 is possible.

Another way to check your NULL is to crank THS-A right up (80-90), adjust THS-B to 40. Slowly adjust THS-B from 40 up (and in your case) through 54 to say 60. What will happen is as you increase the number from 40, the noise will start out very loud then decrease as you get closer to NULL and will be at its quietest at NULL. Then as you pass through NULL the noise level will start to increase again. Take note of the quietest number, it won’t be absolutely quiet but will be the quietest number. Please let me know how you go with this process.

Your mode selection is correct for that coil.

The process I use is as follows:
***Factory reset
1) Set mode
2) Set THS-B to NULL
3) set gain to 6
4) MGB
5) set THS-A up to say 65-75 or until noise level is reached then back off a few until quiet. If you get down to 40-50, drop gain and push THS -A up again.
6) try not to decrease gain lower than 4, but if you have to, then do it, but in this case, I would start again with a higher MODE.
7) once quiet, decrease THS-B below null until noise starts, then up 1-2 clicks until quiet.

Please let me know how you go with this process as this works even in the worst ground.

Ground noise
To determine whether the target signal is a ground noise, determine if your getting a low - high or a high-low target response.
* If low-high, then INCREASE your ground balance by 20 and swing over the target again.
* If it’s a high-low, DECREASE your ground balance and swing over the target again.

If your target response decreases, or moves, or disappears altogether, then it’s a ground noise. Don’t forget to reset MGB back to its MGB number.



Cheers Goldman

Thanks Goldman

This is exactly the feedback I was hoping for. Best explanation of Starting Setup so far on Forum

Can this setup take into account whether you are hunting small or large target.

Or is this the best all round setup

Cheers

Hi Dave63,

Essentially this a setup for general detecting, including small targets. Going under NULL (even by one) will give you more sensitivity and depth than at NULL.

If you have a big coil (18”+), go above NULL by one or two or as much as you can, with a high to very high THS-A.

Once you have ‘set up’, always check to see if you can increase gain without introducing (too much) noise.



Cheers
Goldman

That's a good first report Dave, I noticed you signed up on DP forum too, they'd probably appreciate your first experience with it over there as well.  It's good to let people know how you find using it, a lot of people are interested at the moment in the QED.

It sounds like you're going to take to detecting like a duck to water, you're picking it up very quickly.

Goldman's given great advice in his posts, that should virtually be the Quick-Start Guide to the QED :)  He has an entire thread of QED tips, worth reading/copying to a document the whole thing, it's great.

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


Thanks for your first review of your QED out on your goldfield and look forward to more.

I have experienced the same when raising the GAIN.

yes, that's correct, the higher the mode the higher you can get your gain in tough soils, It would be interesting to know which people should pursue... which would end up to best for sensitivity to small nuggets, a lower mode with lower gain or a higher mode with higher gain?

This intrigued me as well so this morning I set up my test bench outside and the preliminary tests show that a low mode (ie. 1) was getting good sensitivity at low gain 1, through to 8, which was as high as I could go this morning in suburbia.
Settings mode to 5, with gain at 8 matched M1;G4. with gain at 10 it was still behind M1;G8.
With M10, G7 matched M1;G1.

I’m going to try again on a day with less EMI as was a EMI day today, light aircraft, washing machine going, etc but these prelim tests showed that you do get better results with a low mode on small gold - all tests above using a .08g gold nugget.

All tests today were air tests.

Will be very interested in others testing this out and their results

BTW, there is no doubt that you lose some depth as you increase mode.

Cheers Goldman

Thanks for doing that Goldman, as my soil is relatively benign I will get around to testing some in ground targets to see what happens.  Your air test results are what I was expecting.

G'All

Had a chance today to test the setup given to me by Goldman. Went to a local creek known for its old mines for a swing. Car parts old very rusty tools. Panned a couple bits of yellow I could just see.

QED Setup - I followed the setup suggested by Goldman
Factory Reset
Set mode to 4
Set THS- B to NULL - I could not get anything Lower than 50 for NULL

Setting Gain to 6 - This setting just made the the Detector make continual noise - No matter what I did to other settings the noise remained - Again Gain at 2 for a stable machine, Could not get Gain to be stable at 4 as suggested as minimum level.

MGB was very difficult. The Default of 150 was quiet and stable. I just turned to MGB up to 200 and was still stable. Turned it down to 100 and still stable and Quiet. SO I left it at default. - I don't know the effect of to high or low of MGB

THS-A I turned it up to 65/70 detector was screaming so turned it down Hit 40 so started whole process again on a higher MODE. Setting a higher MODE just made the Detector unstable so turned it down to 3 and THS-A was raised to 60 and reduced to 58 to which was to point of a just audible tone

Tried suggested setup multiple times. Ended up back at my original Setup sequence to achieve a quiet stable machine.. Still had the issue of random detector noise High and low tones. None repeatable. Deepest target today was 100mm rusty metal piece.

I cannot do any testing at my home just to much EMI. I have made some test targets .2g, .4g, 1g and 2g. I will have to go somewhere and run some tests. I will try to Video my setup with the external speaker.

I am not keen on putting it on YouTube is there another way a video can be viewed for review and feedback via the forum




Title: Re: QED User Experience\Review
Post by: Dave63 on Tuesday November 19 2019 18:49:14 AEDT PM
Phrunt created a video on his setup. I will test this tomorrow


Title: Re: QED User Experience\Review
Post by: phrunt on Tuesday November 19 2019 19:35:28 AEDT PM
Here is the video showing how I set mine up

https://www.youtube.com/watch?v=z6tGGZ9_57Q&feature=emb_logo (https://www.youtube.com/watch?v=z6tGGZ9_57Q&feature=emb_logo)

This was a completely unprepared unscripted video, I just threw 3 nuggets down on the ground and off I went filming it, I hadn't even turned on my QED prior to turning on my camera,  I noticed in the video because I was showing how deep it can go a majority of the time I kept my coil high up off the ground, only a few times I got it down close to the gold, you'll hear when I do as it roars.  Those perceptive enough will be able to use the shadows to see that.

In Mode 11 ( no ground balance ) I can't rapidly pump the coil in this location on the soil as it will sound off, if I lower it and raise it slower it won't, normal everyday detecting I don't rapidly pump my coil while walking along detecting so that's a small price to pay for the massive sensitivity boost of Mode 11.

This was the weight of the littlest nugget in the video with the big one being 1 gram and the other one in the middle somewhere, I didn't weigh it.

Do these random high and low tones occur when the coil is not moving and well above the ground?

Dave are their any 3 phase power lines near where you are testing? The reason i ask this is because the SMR in the QED will not cancel out the  resulting "EMI" from 3 phase power lines.

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 :  https://www.detectorprospector.com/metal-detector-database/interfacion-qed-r132/?tab=reviews&sort=newest#review-76

Post by: Dave63 on Thursday November 21 2019 18:15:15 AEDT PM
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.

Post by: quasar on Friday November 22 2019 08:12:11 AEDT AM
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.

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

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 https://www.youtube.com/channel/UCCRTukijBOTackaon2JwImQ/videos 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.

Gary.

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

Thanks for the update.

Now I am confused so are you saying when you change to a different MODE setting there is no need to Re-GB?

Also I assume the GB numbers have been returned back to a previous maximum at 200 instead of 300?

Gary.

Hi everyone,

An increment change to the software has occurred very recently that is not sufficient in itself to announce as a new upgrade and not sufficient to ‘redo’ those already upgraded.

Howard and I noticed that on a number of occasions (especially on my training sessions) during winter when the ground was fairly wet that the GB number was getting up as high as 292.

So all Howard has done is to bring the ‘hot ground’ GB point down closer to 150 as rarely is the QEDs GB down in the (very) low numbers. This then leaves more headroom above 150 for unusually hot ground, and still leaves more than enough below 150 for mild to milder ground.

Along the way Howard configured each mode to be at the same relative (electronic) GB position, negating the need to GB with a mode change. This was able to be accomplished electronically in software as there is a very linear GB progression from mode 1 to mode 10, which was made possible as a result of the new GB released as part of the Aug 19 update.

The GB range is still 1 - 300, with 10 modes and mode 11 for beach.

These changes have been implemented in QEDs sold recently and if returned for the ‘Aug 19 update’ and of course will be part of the next update which is not yet on the horizon.

These incremental changes show just how proactive Howard is with little things that make the life of the QED community just a little easier.

Cheers Goldman

Hello All

Well I went out to Dukari GPA for a day trip 2 1/2 hrs there and back. Long day. This is my first time in the goldfields since getting my QED back. 6 Hours Total. Wanted to play with the setting to get a feel for different combos. Found two pieces of lead 10g and 6g they didn't really jump out at me considering they where in the top layer of soil 1st scrap.
I am unsure of my settings as I am yet to find a target that is more than a cm underground. All lead and other metals (In the top layer of dirt)  because of this it is making it hard for me to know if I am getting any depth. Hence me playing around with the settings all the time

I have the amended Firmware update so my GB numbers may appear low compared to AUG 19 update
So today GB was anywhere from 95 - 126. It was hard to tell if I was truly GB as there was very little change in tone across the range

I used different combos of setup to see how it effected the QED.

Factory reset

Sadie Mode 1 worked on all combos
11" Detech Ultra stuck to Mode 3-4
Gain. I tried to maintain Mode 6 throughout, but in doing do I had to have a strong threshold noise
THS-B Null found after Gain set to 6 was from low of 40 to High of 70 Null = 55
THS-B Null found before Gain moved from default low of 44 to high of 62 Null = 53

So avg Null was 54 regardless of Gain

THS-A was the apple that upset the apple cart in every combo I used.

If I set THS-A after Gain and left it at default the QED was basically silent. Right up to Gain of 10.  Raising THS-A to 40 the hum started 65 hum was to loud
If I set THS-A before gain 65 was still silent. Raise gain to 4 hum kicked in, Gain 6 again to loud

In the end I used the QED in what I will call noisy and silent setup
Detech Coil

Noisy:
Mode 3
THS-B Between 49-52 Enhance small targets
Gain 6
THS-A Between 45-55 depending on how loud the hum
GB 109

When I say noisy the tone is not a constant even hum, it is wavy with random beeps through out

Silent:
Mode 3
THS-B 49-52
Gain 6
THS-A default
GB 109

When I say Silent I was getting a lot of random beeps, but these are quite distinct from a target signal

When using the QED I like the fact that I can make it silent, to achieve this either Gain is low or THS-A is low. I am unsure as to the effect on depth.
I need a good test patch. I need to find somewhere near my home and copy the coiltek patch in target size and depth

Thanks for putting up with my reviews. Writing these is helping me gather my thoughts

In this vid when gain lifted to 3 is what I am experiencing in the way of interference. So now after what I experienced today this video make a hole lot more sense

The moment you fit a certain sized coil (small, medium, large) you are creating a bias for a certain range of targets. The higher THS-A, the narrower the NULL adjustment range of THS-B. It's probably best to use either but not both together.

To rule out detector hardware problems, perform the following.
Perform a factory default reset.
Adjust THS-B to null.
Sit the detector on the ground and listen for noise.
Any noise heard will be EMI.
Hit the detector box. If it sounds off it could be

1: Coil plug not tight
2: Fuse not tight
3: Batteries not tight

Tap the coil and wiggle the cable, if it sounds off, faulty coil/cable.
Please let us know how it goes after these procedures.

 Question for Goldman or Howard

QED Pitch adjustment is this Threshold or target adjustment.

Why I ask. I have hearing loss and Tinnitus. Threshold pitch adjustment will give me better Threshold target id

Pitch does not change the ths-a or ths -b trigger points. It only changes the pitch for the audible target response. Range 1-50, with default=25, lower pitch suits older people with loss of high pitch hearing loss

Cheers Goldman

Setting today
Detech 11" Ultra

Factory Default - Hum started straight away

Best results for rest of settings

THS-B 54 ( Null is 55. Tested as Suggested turned THS-A up to 80 and Changed THS-B until most quiet point = 55) Normal up to highest 65 lowest 47 so Null 55 both ways
GB around 100 most of day at some point could not GB unless Gain on 1
THS-A 40 to 65 Depending on noise I could put up with
Gain 3 most stable up to 6 to much EMI noise
Mode 3 Lowering  Mode made noise worst Raising no change from Mode 3

If Gain was on 6 THS-A 40. If THS-A on 65 Gain 2 max

Still a lot of intermittent EMI with coil on the ground and moving.
Did open air test with a piece of .8g gold I have. Best distance I could get about 2 inch. On top of the ground ranged from two inch to having to have coil rest on plastic vile to register.
At max depth of test Difficult to tell difference between EMI and signal. I could only tell because I could see test target.
From what I can see on all the Youtube Vids everyone elses QED seems to be reacting differently to mine

If I was digging down to reveal rubbish targets I wouldnt be concerned as Its only a matter of time to hit yellow, but everything I am finding is sitting on the surface

as you just got back from bugs i cant see it being machine. try these settings...... ths a - 75, ths b -null point, mode 6 with 11" coil, gain on 3 or 4 which ever is quietest. when ground balanced properly should be no spurous noises lifting coil up and down just a nice steady humm. these are all ways my start settings now, it used to be mode 8 before the new update. if this dont work your machine is rat S??? dave. good luck.

OK Here it is 5c 20c 50c test.

Settings best results dasenator777 settings from AEGPF , so much noise if target where in ground I probably would not have ID them as targets. As I could see target I could distinguish target noise

Sadie

MGB 100

B - Null

A - 75

Gain 3

Mode 1

SMF 12,  My default SMF is 109 I may as well been at a rock concert detecting

5c - 22 cm  Clear Signal i would dig 16cm

20c - 19 cm Clear Signal i would dig 12cm

50c  - 22.5cm Clear Signal i would dig 17cm

Northeast Setup

Sadie Coil

MGB 10 0

B -54 (Null is 55) as low as I can go without to much noise

A - 35

G - 1 any higher to much noise

Mode 1 Higher modes no different

SMF - 112 My default SMF is 109

5c - 17cm Clear dig signal

20c - 16cm Clear dig signal

50c - 17.5 Clear dig signal

Just done same test on Detch 11"

Same Settings

NO SIGNALS !!

If I hold the 50c on the coil face all noise stops and then if i rub coin on the coil i get a signal. This will be why I only get targets on top of the ground. !

When I tested detector with Goldman on phone I was using Sadie so I reckon there is still a problem elsewhere. Can a Bad coil screw the rest of the Detector if continually used.

i said mode 6 not mode 1, i can hardly ever use mode 1 maybe mode 3 with 8" coil dave. yes will be noisy inside for sure lol. looks like a coil problem nice easy fix. looking at your review, looks like my settings are a cut above factory default settings though. glad all sorted now mate

That is correct. The target needs to be moving.

What detector do you have that continues to sound off when the target to coil distance remains constant?

I received my new QED ( Warranty Replacement) and Detech coil and went straight to Durikai for a swing.
Found
Buttons
Lead Shot
Boot tacks
Other Metal

Settings
MG 242
B 49
A 45-65
G 4-6
M 4

All finds where in the same area covered by previous QED where I found nothing

Hot rocks where a problem here. Target signal would be in a single spot, but when dug the signal spread across all dug dirt.
EMI I think was why I had to run mode 4. 3 was a bit noisy. 4 was Quiet. Deepest about 19cm that was for a little brass button.
5cent on air test was 19cm also
20cent is weird also least distance on air test. Must be made of different stuff
50cent 19.5cm

Started to rain while I was out. Straight away I wanted a waterproof cover. Definitely needs a dust cover

One point though I ran the sadie for a bit my MG was at 300 got away with 296 very hot area

Very Happy with detector

Again Great Service provided

I am off and running
