Interfacion QED

The QED Metal Detector was first released in late 2016. It was known as the QED PL1 and had only three control buttons on the forward mounted control box. Mid 2018 saw the release of the improved current version, the QED PL2. The QED is a ground balancing pulse induction (GBPI) metal detector aimed primarily at the gold prospecting market. The QED is currently only available for sale in Australia.

"The QED design philosophy was to “to create a performance competitive detector at a realistic price for fellow prospectors”. The result is a single channel Pulse Induction metal detector that’s very well priced in relation to its competitors and has the performance to match the current tier 1 metal detectors of all other brands; you can swing it all day without a harness and bungy and the supplied LiPo batteries last all day."

Features on both the PL1 and PL2 versions of the QED:

  • It can use most of the past and present Mono (round or elliptical) coils, either flat wound, bundle wound, spiral wound or conventionally wound from all of the major coil manufacturers.
  • It has a 5-year Industry high retrospective Manufacturer’s warranty on the QED control box/boxes, which commences from the original purchase date and is transferable.
  • All Software updates are cost-free to units within the warranty period, however the QED Detector owner is responsible for all transport costs to and from the QED Manufacturer (INTERFACION PTY LTD).

Features on the QED PL2 model only:

  • The main box re-located to under the elbow and the Control Box located forward for better weight distribution and better ergonomics
  • 8 Modes increased to 15 Modes to improve performance over heavily mineralised ground
  • The addition of Mode 16 for beach detecting
  • The addition of the Automatic Ground Balance (AGB) function via a newly introduced fourth control button

I would like to begin this review with a bit of background.

A couple of years ago I received a phone call from an old prospector that I had not seen since since the late 1980s when I was involved in testing a prototype pulse induction detector developed by Bruce Candy, one of the original Minelab team. I had tested one of Bruce's earlier VLF prototypes of the GT16000, in the process of which I turned up a 98 oz nugget in a patch of over 300 ozs. It was while I was in London that I picked up a newspaper and read of a new type of metal detector developed by Eric Foster of Pulse Induction Technologies. This detector was finding Celtic gold treasures at depths not achievable with VLF machines. Naturally I was quite excited and on returning to Australia, then to Adelaide, passed on the information to Bruce. Some months later I had a PI prototype from Bruce in my hands.....and the rest is history.

My old prospector acquaintance explained to me that he had met a most interesting electronics 'wiz', who had developed over many years a very compact pulse induction detector, and that he needed someone with experience and credibility to test it for him. Naturally I was curious and the introduction was made. I visited Mr. Howard Rockey who lived not far from me, just out of Ballarat, one of the worlds most famous gold towns. He was a very friendly man who impressed me with his enthusiasm for his project. After showing me his detector (which I must admit looked a little simplistic and perhaps unfinished) we proceeded to his back yard for a demonstration. He had a tiny piece of gold in a clear plastic pill bottle which he tossed onto his lawn. I noticed all the electric wires in the area and thought, "this will be interesting". He turned on the detector, did a quick ground balance whilst explaining to me that his detector was manual GB, then swung it over the target. The response was crisp and very positive, and I have to admit I was a bit taken aback. I then had a play with the machine myself, moving the target to different positions and distances from the coil. I noticed that it ran smoothly despite all the obvious electronics in the area. He explained that it even ran smoothly inside the house.

I left Howard's home with a prototype and over the next few weeks the machine received extensive testing as I familiarised myself with the different settings and mannerisms of the QED. It was quite different to the detectors that I had been used to - it achieved the required performance through procedures new to me. The more I used it, the more I liked it. As its functions became more familiar, my confidence grew. Out in the field, the first small bit of gold turned up after a few days, and I then knew that this was a viable gold hunting machine.

The current PL2 QED is quite an improvement on that first prototype (which I still have and prize greatly) as it has better balance and has some additional features. The mode has been extended, and auto ground balance added (not auto ground tracking). The battery system is now lighter and charging much easier than the earlier version. The controls can be accessed  with the thumb with one hand, making adjustments easy.

I won't go through the functions here as that information can be found within the operations manual, but I will give a few reasons why I enjoy using this detector. Firstly, it is very light and well balanced - I give the machine a very high rating for its ergonomics. Secondly, the target response is extremely positive even on tiny targets, and when fitted with a small mono coil it performs as good if not better than other specialist small gold detectors. Thirdly, although small in size it does not lack power when matched with even very large coils, and comes close to matching even the most expensive of the bigger heavier detectors, punching surprisingly deep.

In summing up...this is not the perfect detector...nor is any other detector I have ever used to this point. The QED suits my detecting style in that I can use any size coil I wish for different circumstances, covering more ground while prospecting new areas. I know that with its sharp signal response I will miss very little. I am confident that this machine will also do the 'low and slow' hunting out of deeper and more elusive targets in previously proven ground.
