QED is here! ML have NOT stopped the QED!
Goldsearch Australia has been appointed the Australian Distributor for the QED. QED info on the Goldsearch website has been updated.
This is the only forum where you can talk directly with the designer/ manufacturer of the QED!
Jrbeatty and Reg Wilson  and  Yellowfin have NO vested  or pecuniary interests(or secret deals or cash for comment or any other undisclosed benefits )in the QED other than using it to find gold which it is doing very successfully!
Over the overwhelming majority of typical Gf ground the QED GB works just fine! Another new user has used his QED over "fairly difficult ground around Waanyarra and Kooyoora areas  " and not reported any GB problems!
The so called QED GB problem is just  more fake news created by  some fake, delusional and dishonest imbecile cretins on 1/2 wits (who is a proven forum hacker and liar and  just dumb!) pox, liars and abomination and disgraceful atrocity sewer rats "forum" that have never used a QED! The QED has been used successfully to detect under 300k steel tower transmission lines(try that with a gp/gpx  with a mono coil!!!) so it  can handle bad  EMI! The QED will also run quite and stable in a household with electrical appliances running.Try that with a ML with a mono coil!!! "QED matches and and in most cases outperforms the SDC"  and will thrash it for depth on bigger gold. QED sales are still strong so if you are on the waiting list please be patient as BW is working 12 hours a day to try and reduce the waiting time.
Except for the USB port the prototype QED's are identical in EVERY respect to the production models and according to the designer  the production models may even be  better!
4umer makes another liar a moderator! How low can 4umer go!

Hi Moodz,

I've made some coils in my time but yours would look the best I've seen, hope there the goods for your project, how would a coil like that go on a normal M/L machine

Yep, nice coils.
happy face

I have been using casting resin too (long time ago). For heat plates & microscope stages with in-built heating resistors. The heat controller was developped by me too.

But I for one would paint the coils with either zinc oxide or
titanium dioxide paint (white paint *LOL*) to protect the resin against the aggressive UV light.

White paint should also protect from the aggressive Greedlab spies. *LOL*

Cheers,
Aziz

Thanks Aziz .... Why did the stages have to be heated?

They turned out a bit better than I hoped ... So thanks Ron. They should work on a ml ... Resistance is OK an inductance is in the ballpark. Would need to add the Faraday shield. I figure the shield is painted\taped on then thin layer of glass cloth over coat of resin ...sanded then gel coat to add durability and protect from UV. However these are test coils for the moodz detector ...

For observing live cells. The temperature must be controlled at somewhere around 37 °C. Otherwise, the cells would "freeze". *LOL*

BTW Moodz,

I for one would add fibreglass fleece to the whole coil structure for more stability. And then fill the coil structure with the casting resin as usual.
That would make up a very stable coil.

You also may add silicon carbide crystals (grained SiC) to the bottom of the coil (before making the coil) and it would protect the coil from grinding. Better you grind off the ground instead of the coil.

That's a good idea ... I thought about adding the fleece or using glass cloth but decided to just use the resin but but down the track definitely will. Adding a layer of sand or sic is a good idea also to make an everlasting coil. IG

 Could the coils  you have made be manufactured to the same quality in  China? If so what do you think the RPP would then be?

I did some quick sums .... They can be made for $60 locally for input costs material and labour to the same quality. Production capacity would be 40 per day for a JIT manufacturing in oz. That capacity would easily fill market demand and is linearly scaleable. I would expect to sell an 18 inc for whatever the market will pay  crushed

Hi Moodz,

Can you weigh it for me as heavy coils just don't cut it when swingin all day, 750gr is okay but when they are a kg that's hard work

Eeeeeeey Moodz,
that is sounding & looking like the "Ultimate Thermo Nuclear Melt-Down" to the coil makers... you're a bad boy! scared
*LOL*
But I want my own SiC grinding disc (coil). Note, that SiC has 9.5 Mohs scale.
^sif

Oh yeah!, the "Ultimate Thermo-Nuclear Melt-Down" is coming to 9r33dla6!!! *LOL*

Hi Moodz,

That is a good final weight, I have a good thing for swinging my M/L machine these days, I hooked a second bungy to the armrest which takes all the weight from your arm and puts it onto the shoulder, all I need to do is swing and keep it away from my feet

Anyways keep up the good work

Ron how do you do it. Diagram or Photo would help as I have not seen or heard of anyone else doing this.

I have been trying to get access to Geotech forum but it isn't working right now.
I'm just curious, what the forum-trolls (aka "bl00dy amateurs") did write there.

Hi Geof_Junk,

My harness is different than anyone elses as well, when you hook your bungy to your harness it has a tendency to pull everything over your shoulder and/or it hooks the harness around the back of your neck

The two things that can counter the weight of the pulling from the bungy aren't utilized in a normal harness, I have the belt that carries the battery as normal and from the battery I have a strap going over my shoulder so as to connect the bungy, but the strap will have a tendancy to ride off your shoulder, so I put another strap from the other part that is heavy, which is the pick, shovel and water bottle and this connects to the strap going over my shoulder

So, I have the heaviest things we carry counter weighting the detecter and to top it off I use two bungies, one as normal and one to the armrest, if I get a chance I will send a photo

What is amazing is that that none of them seem to accept or understand that spider or basket weave type coils can reduce coil losses (higher Q) caused by:
Distributed-capacitance losses
Skin effect
Proximity effect
Dielectric losses
Eddy-current losses in neighboring objects
None seem to understand  that antenna theory is very relevant to  metal detector coils! Its just all about attacking or trying to discredit anyone who is trying to bring a new and competitive non ML detector to market by those that have a vested interest in maintaining the status quo! Its anti competitive behavior at is worst and is certainly NOT in the best interests of consumers, more competition, fairer pricing and  real innovation as opposed to  old drip feed technology!

Doug, you have made the above statement many times, but I am yet to see or hear of any new development that has been stopped by these fellows. Did they stop the Pulse Devil? Did they stop the Gold Sweeper? Did they stop the machine being developed by Finders? Did they stop the QED?

If this coil from Moodz gives "an advantage over ANY commercial coil!!!!!!!!!!!" then it will sell even if it is significantly more expensive than the available commercial offerings. After all, when you pay quite a few thousand for a detector and then a grand or two for extra coils, it would be nothing to pay $700 - $800 for the best coil around. And, Moodz says he can make these coils for around $60 so the argument about cost to manufacture has no relevance.

Anyway Doug, can you point me to ANY new detector development that has been stopped by these fellows who seem to me to know what they are talking about.

Why the antagonism to Moodz? As Carl would say he is not hurting anybody or any company and what he is doing will stand or fall on its merits  which will be decided not by Moodz but by the users and ultimately the market!None of these people including the parrot have his circuits or have any idea of his signal processing  methods or the results of any field trials! All you have is what Moodz has posted! So any negative comments  in my view  have little or no technical merit or validity and are purely speculative or are more likely an attempt by those with a vested in maintaining the status quo interest to try and damage or discredit him!!!
The fellows commenting on the Moodz detector do not know what they are talking about because they are not in possession  of ALL the technical info eg schematics, signal processing etc to make ANY credible and technically valid  points!!!!!!
This is the  same modus operandi used  before to try and discredit any new non ML detector!!!!!!!! its anti competitive and anti consumer behavior at its very worst!
