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:

It may not be rocket science but I can assure you that Howard is in the lead with his technology. I'm just glad that I was able to add an improvement to his design with the new, now patented, front end protection circuit. I am one of the few people who is aware of the improvements that Howard is working on. All I can say is that he is working toward an awesome technology. It may however take him quite a while so keep using your QED's. They will never become obsolete. Good luck with your hunting. Dave Emery, Florida USA.

Thanks Dave for your information.
It's good to know.

Howard is certainly kept busy with new ideas for the QED which only reinforces that he's an honest man which makes him respected by many, even by his haters (they just won't admit it)

All updates to existing QED owners are and will be free
This alone is the best thing for us prospectors.

Thank you and cheers Howard  drinking red wine

Good to hear from you Dave. Yes, Howard's the man to watch, can't wait to see what he comes up with next.  smile

hi bugs/all. what about single phase constant current?

so. what if tx had 2 voltages a high one (500v) and a low one (2-3v) and a diode placed between the 2 , so effectively the sequence is:  tx high & low  on for a few us this raises the current on the diode , then tx high switches off, the current was set at the diode so tx low stays on for however long at that higher voltage.

= reduced ground response + higher current to penetrate ground

HI Howard , ok , so disregarding the higher Tx affect on detection depth. would would having a constant current vs the changing current of the existing design influence ground response and thus ground balance?
In a hand held PI as opposed to a huge coil slung under a helicopter the TX strength doesn't have as much impact on detection distance.

The improved GB method relies on differentiation via TX length. The sample widths remain constant which is a must for cancellation of the signal generated when swinging the coil through the Earth's magnetic field.

Also , what about taking an input after the LP filter to assist in automating the GB....? surely there is some reason why ML and whites are looking at these arrangements? albeit theirs swings from +ve to -ve (bipolar) im suggesting keeping it unipolar.

Or packaging the screen and control  box together? - i've already broken petes bracked and the ribbon cable...

I am looking at a number of ways to improve GB and a form of tracking.
Re the bracket and ribbon cable, no idea how they broke.
The early models had everything in one box up front and it's not good ergonomically. With the coil up front there needs to be weight at the rear to counterbalance it. The control box needs to be light and all controls within thumb reach. This ideal recipe is the current design.

Agreed Bugs.  Used Blips older style QED on the weekend and the newer version is far better ergonomically.  Hope the work re: new GB methods and tracking bear fruit for you (and us).   

Cheers, NE.

Agreed. Current layout ideal. Ground tracking will be the icing on the cake   smile

I’ve used both the PL1 and the PL2 and find the PL2 the best to use ergonomically and functionally.

My PL1 prototype is now a cupboard ornament but found many chunky ozs in its time. Wouldn't hesitate to reinstate it though if the pl2 is having a days sick leave - or whatever.

Let’s not forget that Howard’s objectives in creating the QED was to “create a performance competitive detector at a realistic price for fellow prospectors”, so rest assured that any changes will always have “fellow prospectors” interests at heart and can therefore only make a great detector a really great detector for all of us.

i think i have an early pl2, the bracket broke as it was an early one (like a bent dorito) , now replaced with a piece of bent aluminium. i'm working on the ribbon cable though  ideal would be for it to go through the handle...(. bit hard with a newborn... but agree pl2 is a fair way more ergonomic...

what about a wireless transmitter and receiver as an option?

And the least we can do is provide constructive feedback for all to benefit from from which we have invested in.

The Quest that Northeast was running looked to be a great unit. He was very happy with it.

Another idea for Copyrighting.
Those with a background in Electronics will understand it.

For the  layman could you  briefly  summarize the idea in a few words.

I am very busy ATM so this will be very brief.
Virtually all current PI detectors use sample/integrate method to minimise EMI, remove the ground signal and Earth Field.
This new method finely digitises the decay curve that is then digitally filtered to extract the modulation of the background ground sound by any targets within. The required circuitry would fit inside a matchbox.

An interesting article that is akin to the method.
Transmit a signal then digitally/ear-brain process the reception.
