The way to go Steve H,
I also let it go, no AQ for me anymore they lost me as a client, looking into the Aussie detector QED even without service in the US, when having problems I just send the pot in for service to Down under land, only concern I have is it needs certain adjustment/tuning, for use in gold country in the US what I read. Steve H. Can you tell me what adjustment the QED needs to used in our gold country. I would appreciate any information on this, so I can ask the Aussie maker of the QED to make these ajustments. See this as my experiment for 2020 /2021, I also wouldn't mind to lend my QED as a test machine to you or any other experienced nuggett hunter for experiment testing.
Just want to tell you that I am not a dealer or interested in selling any detectors to prevent any misunderstandings, wanted to do this pet project for a few years. Better do it now and don't want to postpone any pet projects, life is short and I don't know if the COVID19 virus gets me this year or next year! No waiting for me anymore, it' now or never!
It feels very good that this nice forum is at high speed with all discussions about the AQ with all different subjects about the AQ.We are now in the middle of january and still nothing from the Fisher.No reports from any tester, no videos, no manual, nada...it feels kind of depressing without knowing any informations at all.I know that LE.JAG and Alexander can't say anything about these informations even though the know for sure.Is there any thought or any guesses about these questions?
I'm new on this forum and like Alexandre Tartar, I live in north of France.
I was a young prospector in the 90's and asked my father (electronic engineer with good knowledge in magnetic field theory) to build a PI to hunt the beaches. So we have made, in a few months, an home-made PI metal detector 25 years ago, based on the technology of the old White's Surfmaster PI (mono coil). I remember the use of FETs (Field Effects Transistors to make 200 volts pulses). It worked, but unfortunately, my father was afraid by a so powerful magnetic fields and has continued his research on VLF detectors, until today !
After this short presentation, here's my question :
Is the Impulse AQ a bipolar detector ?
Le Jag has explained us on the french forum "detecteur.net" this technology developped by Alexandre :
Positive and Negative pulse are alternatively sent.
The positive one light the gold ring but magnetize the soil.
The negative one demagnetize the soil.
What about it ?
