Climate news
Contribution to global warming by Australia. Australia has one of the highest per capita emissions of carbon dioxide in the world, with 0.3% of the world's population it produces 1.4% and rising(not the .08% the  finders forum dope "Inhere" claims!) of the world's greenhouse gases. Australia also has the highest per capita emissions in the OECD, with 26 tonnes of greenhouse gasses being emitted per person every year.
Australia's C02 emissions rise for the 4th year in a row.

You're a bloody wizard, Howard   excited

Don't you ever sleep?  smile

The Russkie coils are kicking goals on the "Z" (much to JP's annoyance  )

I'll have to try the GPX X mono's on the Kwed when I'm down next.

based on my experience with the 12x6" X-coil on the QED I think you'll be impressed.

The new GB method has been changed again for the better. In addition to an incremental increase of the 2 * short width TX the Long TX is incrementally reduced. It was tested yesterday over a large area of disturbed ground with soils ranging from black to orange clay all damp after recent rains and the GB required no alteration.

Testing with a range of PCB copper targets shows that another benefit is the GB hole for metallic targets is now narrower.

The easiest way to describe how the new "Copyright" GB works is by comparing it to a Metal Detector that has an adjustment pot for GB and the pot is continuously being adjusted up and down.

That's great news Bugwhiskers

cheers

As most would know if using a GPX operating in Fixed GB with a mono coil and a response is received from the ground then moving the coil off to one side away from the response and with the GB button depressed a Re-GB is achieved with a quick pump up and down of the coil close to the ground before moving back over response to verify a ground response from a target. This system of operating in Fxed GB  I would say is used the majority of the time when detecting with a GPX and a mono coil, especially using the timings that allow a mono coil to handle high mineralised ground and not having to rely on the Tracking GB setting that may miss a faint target response at depth.

The QED has been capable of handling high mineralised ground with a mono coil although its GB system is a bit more involved when encountering the same situation as above with a GPX. Therefore if BW can lesson the need.... to use its current Re-GB system by not having to decipher is the response a rising or dipping response and then having to raise or lower its GB numbers by 4 positions or so to verify a ground response from a target..... then that would appear to be a positive move in the QED’s ongoing development.

Hi Eski,
I am at present recovering from the Flu and I don't Video or film in the field I could probably dig up some photo's of the prototypes but they are my build not the commercial ones  all I can say at this time is the production prototypes are on their way to Australia to the Detech distributor where they will be tested before being passed onto me for my final testing if things work out with their permission I will post pictures.

Regards, Ian.

Oki Doki, hopefully they produce the numbers....  Does that mean it will be made (production ) by Detech?

so is Pete the only other tester? Maybe add Mick to the list , he will certainly put it through the paces

G'day Ian.

Have you had a chance to get a hold of the production coils from Detech and what will they be called?

No I have yet to see the prototype but I have seen a picture they have used my coil wind type in a 10" round I believe not my capsule design but believe it will be on its way to me for testing when Pete has finished his testing so I will see what happens but I do have reservations if they do do my design I have asked for it to be called the Broadscan.

Copyright 19 July 2019

The latest advancement in the 2 short, 1 long TX GB method is as follows.
The 2 short TX have an incremental increase in TX length while the 1 long TX has a twice as long decrement in TX length.
Testing has shown the method highly effective in cancelling spurious ground noises (varying degrees of mineralisation),
slightly increased detection distance along with the GB detection hole being narrowed.
GB adjustment is achieved via very small (20nS) changes in the width of the short TX's.
Sample widths and phase (both long and short) remain constant providing very precise Earth Field cancellation.
