Some software and hardware updates now available for the QED.More  QED firmware updates (inc Auto GB  option) just announced here. New  QED hardware updates/options and pictures will be posted  first here  as they become available.

Another satisfied QED user! QED user report for 9 days detecting! User loves it, found it easy to use,found gold with it and he prefers it to his 5000! Also a report on a QED used at the beach for coin shooting.QED users reporting in with their multi ounce gold finds with the QED!
From  another QED user today:"Been out and about today testing and comparing against other machines etc in ground that has been horrible in the past.Bround balancing Ive found very simple and easy.'m using the Nokia booster but need a little more sound/threshold.Otherwise no complaints from me, very impressed."
and :"My QED with the 8” commander on it, out performed my SDC Got bits that don't register on my scales SDC has since been sold"
"My QED is terrific. Lightweight, very sensitive and screams at me when it hits any target. The Detect shaft and the 11" ultra sensing coil is a top quality fitout. I attached an external speaker which added under 200gms of weight in total and still remains very well balanced so i never feel fatigued after many hours of swinging."

Stinky  Pete :http://www.detech-metaldetectorsaustralia.com.au/ is the  Australian distributor for the QED.
This is the only forum where you can talk directly with the designer/ manufacturer of the QED and  also some very experienced QED users.
Jrbeatty and Reg Wilson  and  Yellowfin  (or Doug here for that matter!)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! The ONLY people deriving  an income from the QED(other than finding good gold) are the approved retailer and Bugwhiskers! The ONLY investor in the QED is Bugwhiskers!
I have never met Jrbeatty or Reg Wilson at Howards house or ANY other location!

Hi Moodz,

Where are you at!!, I thought your detector was poohood because of a sixth law or something, is it still happening or is that project gone by the wayside(or sold to M/L).Can you tell us what's happening!!!!

Those coils look the go, low capacitance, fast but I suspect less depth, how do you find them

Hi Ron ....still tracking OK .... I needed to include discrimination so there was some extra work and now I am making some coils to test different coil size vs discrim and depth.

...oh yeah the depth is OK for an 18 inch mono ... How should I make them go deeper. I am also testing a technique to avoid using a Faraday shield. whohoo

Hi Moodz,

Good refit of the 18" coil casing, it looks like some kind of choke fitted , you certainly work outside the square

So all that crap on Geotech about the sixth was just that, crap!!!!

I see the coil but is your you beaut detector still an ongoing thing or what!!!!

I changed from the Wally coil(8") to the 18" mono today ..still nothing, certainly could do with some new science out here, then again if all the gold is gone it aint cumin back, it sure don't grow again and restock

That's what it is....,I should have gone fishin instead, the kids just got back home from Shark Bay with a couple of freezers full of fish fillets and me mind aint on the job

Anyways what else can you tell us about your progresses,

Cheers Ron, Sherri and Yoda(reporting from north of Cue WA)out there doin it!!!

Spider wound coils are the best way to go in my opinion. By far the deepest seeking large mono I ever  saw was a litz wire spider wound coil made  the late Jim Stewart.RIP JIM. Jim also believed in the importance of  potting. No one in my opinion has ever made coils as good as his! Some very lucky person probably has one of his large mono coils!

Hi Ron .. that is not a refit ... that is the mold.  When the resin sets it shrinks about %1 releases from the mold. The choke is the plastic cable strain relief. The detector is still cooking ....just need these coils for more testing of discrimination.

Thanks GL ... The sleeving is silicon airline  normally used for aquariums.  It is super flexible and strong. I extend the coil wire as twisted pair through the sleeving so there is no soldered connections near the coil. If a faraday shield is fitted then a braided sleeve will go over this tubing. The coil shield is a c piece of abs sprayed with aquadag....now who remembers aquadag...LOL.

Casting resin from Barnes.com.au ....400ml required for the 18 inch coil.

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

Hi Moodz,

low capacitance, fast but I suspect less depth, how do you find them

Ron

One would assume this coil will have far less inductance than a minelab coil. Have you measured the inductance Moodz?

If this is the case then it won't  run on a ML detector?
