Ok Funfinder, i got the idea, so i will sum to the friends who are building and testing this divice, to allow me to share expiriencies.
Regards
Nelson

If there is no strong AC voltage field, it has only switch on or off.
To make this device much more sensitive I'll try to find a way to inject some threshold power into the antenna (FET Gate) so it just would take a very small plus of energy to make the FET switch on (or even off, if kept in balance between on or off).
@ goldfinder
Yes, the ion patterns will be the next big project, but still I think even with electrostatic you can detect metallic distortions in the EM-field because I tested this already with that silver ring. In this case was the metal between strong current field and static-detector; but the natural field has some special current - so the detection is more difficult, and especially variable by the ground conditions.

@ Geo
Thank you for your test. You also can rub a plastic ruler somewhere to get a pure electrostatic field.
@ nelson
The best would be you construct it on a still changeable test-basis if we will find further improvements.
@ all
There is two diferent sistems in working LRL devices :
1- The ABSORBTIVE -it absorbs the electromagnetic fields produced by LTA buried metals. It is scientific information that every buried metal(hig conductive) generates an anomaly in the electric and magnetic field of the Earth,iron not produce because its magnetic material,imagine the planet is one gigantic magneto.This diference we can detect with absorbtive Pistoldetektor device.
2-The Ionic/Electrostatic-it detects the electric field of the Earth,it measure and detect the anomalies produced by LTA buried metals generated in the eletric and magnetic field of the Earth.Some people say there is some negative ions or stactic charges around LTA buried metals,this is associated with the phenomena.
Afaik Esteban wrote this - the 2nd point concerns electrostatic.
So is somebody here with some lta buried object in garden who can test it with a electrostatic-detector?
btw. if the FET recognises electrostatic only from higher voltages would it be a good idea using a transformer coil like used for kV in TV units?
Usually transformers only work with AC but maybe for only switching the FET on or off also a DC current field could be transformed (0.1V into 100V - transformation factor 1000). Do Tesla coils have such a high factor?
The final construction would consist in a large plate or magnet-coil antenna (I guess the "around the PCB antenna" of Mineoro also is magnet-coil style) that is connected to the transformer coil for getting higher better recognisable voltages - finally attached to the JFET or MOSFET.
If we have the experimental proof there really is an usable electrostatic potential with LTA treasures we can perfectionate that kind of detector, otherwise we have to switch to the next one.

Instead just making comments like some others here now I build a nice large antenna, using the both top-covers of two old DVD-players.
The size is about 47x50cm and for transportation just 25x50cm. Weight incl. detector ca. 1kg.
It's crazy - it already recognises if I move my fingers while holding and beeing near some electricity-cable!
Those now get detected from 1,5m.
And if I'm leaving the detector there it recognises when I'm coming near from around 50cm distance.
I'm curious what outside tests will show.

I remember Dr. Best got excellent results locating gold with his advanced pyramidal logarithmic quadro spiral antenna, using carbon litz technology.Originally posted by WM6Dr Best send you compliments on this smart antenna. Me too.

But of course, his detectors were not simple static field detectors. They depended on ion migration.
In this application, it is easy to see that success for detecting static charge is improved by the size and shape of the detecting element. The formulas for a static field strength are well known for different sizes and shapes of conductors. For a 2 dimensional plane, size matters. The bigger, the better.
Scavenging parts from electronic enclosures or appliances to make a large antenna element will quickly reach a point where no further improvement can be made due to limited size of available appliances. For truly improved results I would suggest that you remove the roof of a car. This will make a large dished antenna element guaranteed to outperform any electronic enclosure or kitchen appliance parts for detecting static charges.
Best wishes,

@ Qiaozhi
Very cool E-guitar design - has something from H.R.Giger (Alien movie design).
But for what is this hitec pistol?
@ WM6
You confused DVD-Player with micro-wave! Or do you cook your salami-bread with the DVD?

@ J_Player
Absolutly correct - the larger the electrostatic electrode surface the better - and i think I reached already the useful portable size.
The gain doesn't double in sqare-cm but is more like this (round plate, electricity cable):
no antenna (5cm wire) 20cm
10cm wire: 40cm
20cm diameter plate: 70cm
30cm diameter: 1m
50cm (my new antenna): 1m50
So with an 1m antenna you could get around 2m but for outside usage it starts to get problematically (especially if its windy) and really heavy. So the reasonable maximum size is reached.
_______________________________
Anyway - Morgan and Esteban pointed me/us in direction electrostatic so I want to find out if it works or not. Otherwise we can't rely on any information here!
The new test has shown that the holding person of such an electrostatic detector also works as an antenna - the same if a person with sensitive MD has a shovel in his other hand.
Therefore it could become problematically to construct a very sensitive detector that can recognise positive and negative static fields - it always would or could detect the holding person.
Perhaps in the future I use this new antenna as a shield while the real antenna is in front of it. Electrostatic works like loaded capacitors so the antenna also should look like such.
If I would skip the whole "electrostatic stuff" for now I would be never be shure if it works or not, so even that I'm more curious how the PD passive receiver works I hope that I find a way to make the FETs recognition more sensitive and better positive-negative static recognisable.
Therefore perhaps I build this circuit again and see what further improvements still could be made. Adding a mVU-Meter, a transformer coil to the FET and other signal-amplificaton stuff.
Well, so the field above the treasure is positively charged, while the detector holding person is negative grounded?Static Sound increases if treasure is near
As you can see - still too many important questions we need answers for.

btw. I had already an electrostatic receiver!
It's a 2in1 wiresearcher from multiTEC (Made in China, ca. 10 years old) but it doesn't use FETs, just simple transistors (9014, C9014).
The windings are ca. 130 / 35.
The LED also is 2in1 with green and red light, depending if metal is near or with blinking if electricity flows in the cable.

@ WM6
What with singin' and blinkin' is? You're confusing this with disco detection by the light beam at night!
Or ask Jan Plestenjak what is with singin', he sings at the moment at my Sat-TV. Or now: Ela - Glas Sirene - with a little bit blinkin' "bling bling" we better find with MDs than buying... 
But now I found out what we really need is called: "field mill". It is the most sensitive electrostatic detector - down to 10v/meter while our detectors only have around 1kV.
Weather stations and airports use it to collect smallest changes in electrostatic field. But we need one that is not fixed to ground.
And I found a second important fact:
If this is not grounded, the electrostatic flows around a metallic object.
So the question is, how "untouched" the buried metal object remains within the ground by the electrostatic field and what effects the ion-imigration "halo" causes.
A person, standing on ground is negative loaded by influence (=electrostatic interaction).
And on cloudless sky there is 100 V/m to 300 V/m static charge. This can raise (at thunder and lightning) up to 25 - 35 kV/m. Ion concentration in air has also large differences.
btw. there are exists also alot mechanical electrostatic detectors - even the radioactive elements like Polonium had been detected by them long time ago by couple Curie, because of ionisating the air around. Those devices detecting the physical attraction force of strong electrostatic forces but are too sensitive for outside.
And I doubt the field mill alias rotation-voltmeter with it's little holes has enough sensitivity compared to a electrostatic-detector with 50x50cm antenna. It may be possible, if very sensitive parts are used, but we have to find it out. At least the difference between some 10volt/meter would detect the buried treasure alot better as some detector that only recognises changes of 1kV/m.
