Interfacion Pty Ltd is pleased to announce that the QED PI Detector has been modified to allow the use of DD (double D) coils. This change involves a simple change to the electronics within the control box.
The firmware has also been upgraded to include a further improved Ground Balance.
All detectors being delivered to new customers from Monday 5th August 2019 will already have the above upgrades included.
As a show of commitment to all QED owners, the hardware modification to allow use of the DD and CC coils will be provided at no cost.
Of course and as per the QED warranty, the firmware update is provided free of charge, except for P&H.
Any QED owner who plans to attend the Laanecoorie Bash is encouraged to bring their detector along and have it upgraded at no cost.
Standard postage and handling arrangements apply to other owners. Send via Australia Post the box (minus batteries) along with a pre-paid, pre-addressed bag/box to:

You're a bloody wizard, Howard   excited

Don't you ever sleep?  smile

The Russkie coils are kicking goals on the "Z" (much to JP's annoyance  )

I'll have to try the GPX X mono's on the Kwed when I'm down next.

based on my experience with the 12x6" X-coil on the QED I think you'll be impressed.

The new GB method has been changed again for the better. In addition to an incremental increase of the 2 * short width TX the Long TX is incrementally reduced. It was tested yesterday over a large area of disturbed ground with soils ranging from black to orange clay all damp after recent rains and the GB required no alteration.

Testing with a range of PCB copper targets shows that another benefit is the GB hole for metallic targets is now narrower.

The easiest way to describe how the new "Copyright" GB works is by comparing it to a Metal Detector that has an adjustment pot for GB and the pot is continuously being adjusted up and down.

That's great news Bugwhiskers

cheers

As most would know if using a GPX operating in Fixed GB with a mono coil and a response is received from the ground then moving the coil off to one side away from the response and with the GB button depressed a Re-GB is achieved with a quick pump up and down of the coil close to the ground before moving back over response to verify a ground response from a target. This system of operating in Fxed GB  I would say is used the majority of the time when detecting with a GPX and a mono coil, especially using the timings that allow a mono coil to handle high mineralised ground and not having to rely on the Tracking GB setting that may miss a faint target response at depth.

The QED has been capable of handling high mineralised ground with a mono coil although its GB system is a bit more involved when encountering the same situation as above with a GPX. Therefore if BW can lesson the need.... to use its current Re-GB system by not having to decipher is the response a rising or dipping response and then having to raise or lower its GB numbers by 4 positions or so to verify a ground response from a target..... then that would appear to be a positive move in the QED’s ongoing development.

Hi Eski,
I am at present recovering from the Flu and I don't Video or film in the field I could probably dig up some photo's of the prototypes but they are my build not the commercial ones  all I can say at this time is the production prototypes are on their way to Australia to the Detech distributor where they will be tested before being passed onto me for my final testing if things work out with their permission I will post pictures.

Oki Doki, hopefully they produce the numbers....  Does that mean it will be made (production ) by Detech?

so is Pete the only other tester? Maybe add Mick to the list , he will certainly put it through the paces

G'day Ian.

Have you had a chance to get a hold of the production coils from Detech and what will they be called?

No I have yet to see the prototype but I have seen a picture they have used my coil wind type in a 10" round I believe not my capsule design but believe it will be on its way to me for testing when Pete has finished his testing so I will see what happens but I do have reservations if they do do my design I have asked for it to be called the Broadscan.

Copyright 19 July 2019

The latest advancement in the 2 short, 1 long TX GB method is as follows.
The 2 short TX have an incremental increase in TX length while the 1 long TX has a twice as long decrement in TX length.
Testing has shown the method highly effective in cancelling spurious ground noises (varying degrees of mineralisation),
slightly increased detection distance along with the GB detection hole being narrowed.
GB adjustment is achieved via very small (20nS) changes in the width of the short TX's.
Sample widths and phase (both long and short) remain constant providing very precise Earth Field cancellation.

 along with the GB detection hole being narrowed.


Hi BW,

it is not fully clear mean of "being narrowed" phrase for me.

Does this mean that QED is able to fully overcome so called "detection hole" problem?

If so, then this is really significant and important achievement.

As far I know no GP(X) model is able to cope with detection hole problem?

The method employed to test the "width" of the GB hole is the use of squares of single sided copper PCB.
The pieces have a 5mm increase in size eg 65mm, 70mm, 75mm etc.
The hole is around the 70mm piece. This does not mean that a nugget that is 70mm*70mm will be in the "hole", far from it. The copper is only 30uM thick so the actual metal cubic size is very small.
Testing shows a very wobbly signal at about 5" from the coil with the 70mm piece. The PCB sizes either side (65mm & 75mm) are detected at around 14". The next sizes 60mm * 80mm are seen an additional few inches out. If the "hole" were broad the 65mm & 75mm would only be seen at around 7"-8".
Sizes below the "hole" produce a rising pitch and those above a falling pitch.

An excellent outcome BW.  happy face
Whats that ground noise we hear? Perhaps the sound of applause from the deep, from PW and diggers.  Bravo Clap Hands  Clap Hands

The improvement, you call “highly effective” in cancelling ground noises, is a BIG claim for a new design. It will be heralded by all active prospectors when available. That may even include me one day. When matched to improvements in coil design / performance, the QED II should make for rippa of a lightweight tool.  

Have you bench tested it? When will it be 'adapted & arranged' into reality and a prototype? Do we assume it will require new hardware and software design ie a New QED?

You explained the 'narrowing of the hole' very well. Thanks. Its very clear. You can expect that the hole (target size) will be used in tests eg by critics to try diminish it. But like PL2 its many attributes of QED II will see it shine above the other prospecting tools... AGAIN!

I looked back to a BW post of June 26 and can see GB with new copyrighted method HAS BEEN FIELD TESTED.
Again, an excellent outcome BW.  Clap Hands

What if that "hole" narrowing continued, compressed until it was almost a line? Hey, then the likelihood of any real world target matching that size / line precisely will be so unlikely it can be ignored. Limitation GONE!

Huego  happy face

edit: maybe such a very compressed hole / line can be "cut out" ? ..to provide further improvements

Thanks Eugene, it may be possible to get rid of the hole all together but other things are more pressing ATM.
The changes are all firmware so just a reprogram is required.
Re the use of DD or co-planar coils (separate TX and RX), just a minor hardware addition is required ie a switch on the front endcap and a couple of resistors added. If the RX coil was the same resistance as the TX then it would work without modification.
Firmware changes are free, the owner just pays postage both ways.


I am disgusted with AUSPAT and the shenanigans I have witnessed ie Detector patents being examined and granted by staff in the "Plant Breeders Rights" department. Changes made to pending patents by good customers of AUSPAT without losing priority date, the list goes on and on.
