QED news
New GB timing algorithm being tested in the QED.
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.

It may not be rocket science but I can assure you that Howard is in the lead with his technology. I'm just glad that I was able to add an improvement to his design with the new, now patented, front end protection circuit. I am one of the few people who is aware of the improvements that Howard is working on. All I can say is that he is working toward an awesome technology. It may however take him quite a while so keep using your QED's. They will never become obsolete. Good luck with your hunting. Dave Emery, Florida USA.

Thanks Dave for your information.
It's good to know.

Howard is certainly kept busy with new ideas for the QED which only reinforces that he's an honest man which makes him respected by many, even by his haters (they just won't admit it)

All updates to existing QED owners are and will be free
This alone is the best thing for us prospectors.

Thank you and cheers Howard  drinking red wine

Good to hear from you Dave. Yes, Howard's the man to watch, can't wait to see what he comes up with next.  smile

hi bugs/all. what about single phase constant current?

so. what if tx had 2 voltages a high one (500v) and a low one (2-3v) and a diode placed between the 2 , so effectively the sequence is:  tx high & low  on for a few us this raises the current on the diode , then tx high switches off, the current was set at the diode so tx low stays on for however long at that higher voltage.

= reduced ground response + higher current to penetrate ground

HI Howard , ok , so disregarding the higher Tx affect on detection depth. would would having a constant current vs the changing current of the existing design influence ground response and thus ground balance?
In a hand held PI as opposed to a huge coil slung under a helicopter the TX strength doesn't have as much impact on detection distance.

The improved GB method relies on differentiation via TX length. The sample widths remain constant which is a must for cancellation of the signal generated when swinging the coil through the Earth's magnetic field.

Also , what about taking an input after the LP filter to assist in automating the GB....? surely there is some reason why ML and whites are looking at these arrangements? albeit theirs swings from +ve to -ve (bipolar) im suggesting keeping it unipolar.

Or packaging the screen and control  box together? - i've already broken petes bracked and the ribbon cable...

I am looking at a number of ways to improve GB and a form of tracking.
Re the bracket and ribbon cable, no idea how they broke.
The early models had everything in one box up front and it's not good ergonomically. With the coil up front there needs to be weight at the rear to counterbalance it. The control box need to be light and all controls within thumb reach. This ideal recipe is the current design.

Agreed Bugs.  Used Blips older style QED on the weekend and the newer version is far better ergonomically.  Hope the work re: new GB methods and tracking bear fruit for you (and us).   

Cheers, NE.

Agreed. Current layout ideal. Ground tracking will be the icing on the cake   smile

I’ve used both the PL1 and the PL2 and find the PL2 the best to use ergonomically and functionally.

My PL1 prototype is now a cupboard ornament but found many chunky ozs in its time. Wouldn't hesitate to reinstate it though if the pl2 is having a days sick leave - or whatever.

Let’s not forget that Howard’s objectives in creating the QED was to “create a performance competitive detector at a realistic price for fellow prospectors”, so rest assured that any changes will always have “fellow prospectors” interests at heart and can therefore only make a great detector a really great detector for all of us.
