Welcome to the official site of the QED Metal Detector.

The QED is an Australian designed and manufactured single channel Pulse Induction metal detector.

  • QED Design Philosophy

    The QED design philosophy was to “to create a performance competitive detector at a realistic price for fellow prospectors and one that you could swing all day without a harness and bungy.”

    The result is an Australian designed and manufactured single channel Pulse Induction metal detector that’s very well priced in relation to its competitors and has the performance to compete well with current tier 1 metal detectors of other brands.

QED History

Figure 1 – Shows the PL1 on the left, then the PL2, then the PL3


The QED Metal Detector was first released in late 2016 on the anniversary of the 162nd Eureka Rebellion. It was known as the QED PL1 and had only three red control buttons on the forward mounted control box.


The PL2 was subsequently released, again with a forward mounted control box, but this time with four control buttons.


Mid 2018 saw the release of the QED PL3 which had some important improvements: The main control box was re-located to under the elbow and the Button 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

PL3 Aug 19 Upgrade

In Aug 2019, a major upgrade occurred to the PL3, whereby the following changes were incorporated: A significant improvement to the Ground Balance Technology, called DSM, was introduced

A reduction to 10 Modes for general detecting in the Goldfields

Beach Mode became Mode 11

The capability to run DD Coils for the first time.


2021 PL4 released. Collapsible handle, light weight, multiple battery options including 15 Ah Powerbank providing approximately 30 hours use between charges.

QED Advantages

The major advantages of the QED are: It can use all of the past and present Mono and DD (round or elliptical) coils built for PI Metal Detectors from all of the major coil manufacturers.  The coils can be either flat wound, bundle wound, spiral wound or conventionally wound. Obviously, this excludes coils built for the SDC2300 and the GPZ7000. Note that the new CC coils do work on the QED, but are less effective than the performance when used with the Minelab GPX series of Detectors.

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).
