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! More QED users reporting in! QED users are reporting that they do not find "bias drift" an issue!
The QED pictured is backward compatible with the current QED and has been designed and made by a member here. The firmware and circuit are identical with the current version except for a change in the face plate and control box. Changing to this configuration will NOT void the warranty when performed by the control box designer as it has been endorsed, approved and authorized by the QED manufacturer. The 4th button will not work at this time as the  firmware update for that has not been created yet and when its available will be provided free of charge (other than postage costs)by BW. QED Detector ,latest updates board is only available to registered forum members.

Goldsearch Australia has been appointed the Australian Distributor for the QED. QED info on the Goldsearch website has been updated.
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!

Interesting info, thanks GL!

I am relatively new to using PI machines but have a tech background in electrical/electronics, and find the tech side of prospecting just as interesting as finding nuggets. Now I find myself needing to know more and the geology of gold bearing ground and stuff like what makes a good coil even better. Its an interesting hobby and now that I'm retired its also a great form of exercise. Whats not to like?

I spoke by phone with CoilTek today about their "new technology" in the 14" Elite Mono and discovered the following.

It is new tech being used, (based on established theory) by them for the first time in manufacturing this coil. The new mono coil is still a single coil, but is now wound in such a manner as to align the coil's field strongly vertical. Horizontal field spread from the edge of the coil has been reduced and the increased vertical field provides the better depth and sensitivity that is being noted and measured by those using the coil.

Its finally nice to know that the increased depth and sensitivity provided by this new coil has sound science behind it and not just the camo paint job! CoilTek indicated to me that the method used in winding this coil and the type of coil that results is suitable for some other size coils but not all. Nice to see innovative products still being introduced for the GPX, etc detectors.

Its also interesting to note that after CoilTek released their new 14" Elite to market that NF started making it known they were working on a similar coil. Strange how that happens and probably just coincidence but I guess you can never get too much of a good thing  smile

Hi Ian,

In those links to Azizs posts that I made earlier on in this thread.
Aziz shows how varying the pattern of layering/wraps can be beneficial. Especially compared to just plain old bundle winding.

Imagine a coil with a fixed number of turns of wire. You could adjust the profile of the finished bundle so that the coil bundle profile is wider... facing the target/ground.  Like a wider fishing net, so to speak. A a slightly more rectangular one, compared to square profile.

I think Stefan, IBGold and authere have been experimenting with coil-building and found out a lot of interesting things, empirically, over the years.

Aziz  used maths and his coil software to demonstrate some of these things.

The fact is that manufacturers are going to closely guard their methods, for obvious commercial reasons.

Thats why we should be grateful for forum hosts and forum posters who are willing to share. Unfortunately some just leach and try turn what they have learned into a quick buck, or a patent......

Fact is most of what we can buy today is just a mix and mash and finely tuned rehash of age old principles.
