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:

Appreciate the efforts by those who took time out to run tests with their QEDs on the 50c coin.

The results show the QED does not respond to the 50c coin as good as the results in my opening post with the GPX.
I would then have to say the same would apply to other coinage of the same composition.
Therefore it seems selecting a consistent target to evaluate the differences between detectors is problematic.
The use of Lead, Aluminum or Copper have been used over the years to try and do that particular assessment.

I now see desenator777 believes he may be able to squeeze more out of his QED using his other small AMP and RPG headphones.
Both 777's NF20"mono at 44.5cm & Blip's NF20"mono at 48cm came the closest to the GPX4500 in Enhance on the 50c coin including Goldman's results of a 4500 in Enhance as well.

To be valid, comparison test should be done in direct competition (at he same time and same location) and not by comparison of some tale stories from different sources.

where i tested was heaps mineralised as seen by gb numbers, magnetite brecciated quartz and mud stone/iron stone.rubble every where, same place we found the copper samples last year. coin was put on ground and coil passed over it, then measured with one of those fold out plastic builders ruler. i reckon i can still squeeze more out of it using the other small amp and rpg head phones. will try again over the weekend.

Yeah high GB’s for sure and your 8” in mode 3. I can run the 11” Commander in mode 1. Trying to push the mode can have quite a large effect on the GB. Im yet to determine whether i have an issue with the 11” Minelab. Ill find out later this week.

the 8" became a bit erratic in mode 2 AL, mode 3 was stable. a not so minerised area would allow me to get to mode 1 i think, il try it over the weekend mate. you beat me on the 20" by 3.5cm cant have that lol.  excited

Oh absolutely. Our differences in detection would come down to your high mineralisation and possibly because our air tests were performed differently.

I did repeated tests with the NF 20” and i got a slightly stronger single at the edge of the coil. My coil was on the ground where i waved the target above. Also the ground i was in was full of trash being an old house site. I found a very small spot to be able to balance in. Later in the week ill return to a spot i know is very stable.

Tall stories? Hmmmm! I dont know what makes him think they are tall stories! I checked and rechecked. More tall stories to follow!

Therefore we will need to use Goldman’s comparison test results between a 4500 and QED as they were done in direct competition at the same time and same location.

Gary.

All direct comparative tests that exist are better than to compare assay results from different sources.

Namely this thread start with this:

"I read some test results, be them in air above the coil, using a 50c coin and a 4500 set in Enhance with an 18" mono = 63cm, 15" Evo = 64cm  & 19" Evo = 65cm and they were all fairly similar.

Therefore I am curious with what size mono coil and settings on the QED would be required to produce a similar result with the 50c coin?

Goldman if possible could you do the same test with your QED."

Well I have tested a QED and a 45 with both a 50c Australian coin and a 1oz gold nugget in the goldfields around Maryborough, vic.

QED using the standard speaker:

Not sure what difference using a SP01 audio enhancer with headphones on the 45 Vs the QED standard speaker made to the results.



You would have to think the SP01 audio enhancer and headphone made a difference on the 45 if we are to believe those on the forums who speak of the SP01 advantage.

As BW said "using headphones it is easier to hear a faint signal. Couple this with the pitch change being heard long before the signal volume goes up it's possible to hear a faint target 25%-30% further out" so using a headphone on the QED for the test could have improved the result since a headphone was used with the 4500.

Also in regards to the SP01 audio enhancer used on the 4500 for the test then I have not really tested if an external audio amplifier or enhancer makes a difference depth wise except for extra volume control on the QED, although maybe other members here with the QED have?

Gary, personal experience with the external amp tells me that it only amplifies the sound not detection depth so it is easier to hear faint signals that otherwise maybe missed.

Im not up on the SP01, but i see it as doing the same thing but in a more sophisticated manner.

I've had no luck getting good results out of my SP01 on the QED, works fine on my 4500 but the volume's just too low on the QED for it to work properly.  It does work, the volume it puts out is just too quiet, it doesn't go super loud like on my 4500.  On the 4500 the SP01 is brilliant.

Steelphase even made me a special cable to try use it on my QED but the results were no different.

Thanks Al so being able to hear faint signals that may have been missed do we call that as producing extra detection depth then I suppose so if the Amplifier can further amplify the pitch change as BW mentioned with the use of a headphone.

Therefore the Amp combined with a headphone it may be possible to hear a faint target further away than the 25%-30%.

I expect the best way to verify would be on a faint target in the ground that can be detected while using the Amplifier then disconnect the Amp and check if the target can still be detected.
