Hi J:Player and thanks for your time and comments.
In other words i think we must still be waiting for someone that realy wants to share somethink that realy works.
All time inverting on a device that can work is well welcome, but when you see that some people work here to experiment and learn from all members tips and things to get a good working pdk and after get succes, desapear from here and share nothing in concrete.
Some people are electronics enthusiast and some others have an electronics degree, and if we are here to learn, work and build metal detector has a group of people that share information, i don´t understand why they don´t do that.
They said that basic pdk circuit works, but i had made lots of experiments with no succes.
In my case i need pdk, for locating some treasures for my own personal use. If someday i get a workable pdk, this will never be for sale. The price of a tresure is much higer than the price of pdk.
Andreas send me long time ago his work about long range metal detector, but unfortunaly i lost that information sended by email. So if you or someone have it, please send it to
nlepet@gmail.com
I know Andreas LRL, have the clues to complete pdk work.
Sorry for my english, pdk work have somo limitations by now, cause the ones that can help, now seems not be interested to help to the point pdk workers can get their machines work properly. I miss Esteban posts, cause he is the real master about LRL and pdk.
Regards
Nelson

"Maybe there's nothing to patent... or all this stuff was already patented by Fisher in 1930 ! 
But but but , this circuit is interesting as a different approach ! That's what I think.  "

We find that Max was wrong. The basic circuit we see was designed by Heathkit engineers in the USA, and was sold as a kit including all parts, for home builders to assemble in the late 1960s.
This is what Fred said about it: "But i make a big difference between this pistols and the mineoro´s , that even if they may be based on the same ideas, have been too far away from workable principles".
