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:

I am yet to view any video evidence to convince me that a spiral X-Coil is any better than the same size flat wound NF or CT when used on a GPX or the QED so I won’t be parting with the flat wound Evo.

I was hoping to video compare the 15x10" X-coil with the NF 14x9" EVO for you today but unfortunately I didn't get a chance, I'll try in the very near future.  The 15x10" is the closest size X-coil I have to an EVO.

Gain - Adjusting Gain up above 2 produced an unstable response from the QED so 2 was the max setting for most of the trip. Adjusting Gain up also effected the tone produced by THS-A. I put the Gain up and went back to THS-A to try and adjust the tone out. This had no effect. So reset THS-A and lowered Gain to make detector stable


Thanks for your first review of your QED out on your goldfield and look forward to more.

I have experienced the same when raising the GAIN.

Gary.

I messaged    about the x coils. He is located in NSW and is the sole reseller of the x - coil from Russia. I read about them on Detector Prospector Forum. He told me a specific individual is testing the 12"x6" x-coil on the QED. I will be very interested to see the review when testing finishes.

The coil are not cheap $650 AUD. The coils are not really available yet so hopefully the price will come down when in full production.

Indications are that the coils are very good.

Cheers

I thought the climate change deniers shut you down :)


Nah my fault entirely although the  host did not make it entirely clear what was to be done and after the  server upgrade. The host says that the forum should load a little faster and be more stable and secure. Some  fraudsters are now phoning me or sending emails saying that the forum domain name has expired and that  through them(pay be credit card!) i need to restore it ASOP!

That's a good first report Dave, I noticed you signed up on DP forum too, they'd probably appreciate your first experience with it over there as well.  It's good to let people know how you find using it, a lot of people are interested at the moment in the QED.

It sounds like you're going to take to detecting like a duck to water, you're picking it up very quickly.

Goldman's given great advice in his posts, that should virtually be the Quick-Start Guide to the QED :)  He has an entire thread of QED tips, worth reading/copying to a document the whole thing, it's great.

Thanks Goldman

This is exactly the feedback I was hoping for. Best explanation of Starting Setup so far on Forum

Can this setup take into account whether you are hunting small or large target.

Or is this the best all round setup

Cheers



Hi Dave63,

Essentially this a setup for general detecting, including small targets. Going under NULL (even by one) will give you more sensitivity and depth than at NULL.

If you have a big coil (18”+), go above NULL by one or two or as much as you can, with a high to very high THS-A.

Once you have ‘set up’, always check to see if you can increase gain without introducing (too much) noise.



Cheers
Goldman

Hi Dave63,

First thing to do is to absolutely know what your THS-B NULL is. 54 is a little high from my experience, however as each machine is slightly different and depending on prevailing conditions at the ‘factory’ during final post production setup, a NULL of 54 is possible.

Another way to check your NULL is to crank THS-A right up (80-90), adjust THS-B to 40. Slowly adjust THS-B from 40 up (and in your case) through 54 to say 60. What will happen is as you increase the number from 40, the noise will start out very loud then decrease as you get closer to NULL and will be at its quietest at NULL. Then as you pass through NULL the noise level will start to increase again. Take note of the quietest number, it won’t be absolutely quiet but will be the quietest number. Please let me know how you go with this process.

Your mode selection is correct for that coil.

The process I use is as follows:
***Factory reset
1) Set mode
2) Set THS-B to NULL
3) set gain to 6
4) MGB
5) set THS-A up to say 65-75 or until noise level is reached then back off a few until quiet. If you get down to 40-50, drop gain and push THS -A up again.
6) try not to decrease gain lower than 4, but if you have to, then do it, but in this case, I would start again with a higher MODE.
7) once quiet, decrease THS-B below null until noise starts, then up 1-2 clicks until quiet.

Please let me know how you go with this process as this works even in the worst ground.

Ground noise
To determine whether the target signal is a ground noise, determine if your getting a low - high or a high-low target response.
* If low-high, then INCREASE your ground balance by 20 and swing over the target again.
* If it’s a high-low, DECREASE your ground balance and swing over the target again.

If your target response decreases, or moves, or disappears altogether, then it’s a ground noise. Don’t forget to reset MGB back to its MGB number.



Cheers Goldman
