some cosiderations

[Max]

I'm the cure ! For LRL-madness I mean

No, I'm searching for a good doctor!

You don't trust Dr. House ?
Ok ok... could be brutal on methods... but results are guaranteed!

[J_Player]

I think Dr. House is wrong spelling.... should be Dr. Horse... for make repairs to horse.

Best wishes,

Dr. House could repair anything. Even you !

Hi Esteban
Can you tell me if there is an electric connection between the handle and the circuit of your "pistol" and if you use 3 X 9V battery as Mineoro? I have realized a TR-IB at 30 Khz, with Sync-demod.- push button retune - CC amp - and the receive coil is followed by very high impedance amplifier with Fet in bootstrap configuration. The first test out my home is negative (no gold in my garden...) but signal is very stable.

Hi FrancoItaly

There is not connection in handle, for example no to negative lead. I can obtain minimal variation of hz in the coil since 55 to 60 Khz.

I think your find indicator is the vumeter, but this is insensitive to low changes. You need an audible indicator, you can put in limit the beeps with the sensibility potentiometer. No speaker, yes a piezo buzzer.

With 59 Khz oscillator I found gold Navy button (in the first search) and some coins, but at this frequency the movement of pistol in hand must be some slowly. I try all my experiments in house and sites with good quantities of relics.

Hi Esteban
I thank you for help, in my instrument I measure a phase change in the receive coil respect the transmitter oscillator and I have also an acustic beep by a piezo buzzer.

Hi FrancoItaly.
Can you explain me why you have put the white grid in the center and the front place of the coil? If i see good at the center is there a small coil vertical with the big one??
Regards

[FrancoItaly]

Hi Geo
the white grid is the antenna connected to the small receive coil that it's orizontal and this forms a TR-IB with the big vertical coil. I think (or perhaps I hope) that the magnetic field of the transmitting coil it can influence the ionic or electric existing field. Also a small pertubation it can be sensed as a change in phase in the signal amplified in the receive coil.
The screen acts as a virtual ground and it's shields the body. My instrument is a free interpretation of Esteban's pistol...

Hi FrancoItaly .
Thanks for your info, but i believe that it is better to play with am de-modulator than with phase shift. For me the problem with pistols type LRL is how to discriminate the gold and not how to locate from long distance.

Hi Geo
I rectify, I use a syncr. demodulator equal to VLF metal detectors. For me the problem is also to locate any metal from long distance.

Hi Franco,
short range detection is the problem of metal detecting from origins.

The real problem is that the "solutions" like zahori-circuits can't give any help to locate metals!

So you can use a magnetometer for iron stuff... but there's nothing to detect e.g. a gold ring from 10meters or 1mile.

Are all fantasies and dreams, or stories (and often even frauds).

That's the absolute (and sad) truth.

Best regards,
Max

Hi all .
I wrote before some time that i have tried the Andreas dillinger and it works from long distance. Also i saw the Vertex to locate gold coin from 300m up on the ground, not inside the ground.
So i do not accept you to say me that they do not work "Are all fantasies and dreams, or stories (and often even frauds)". I accept that they have a lot of other problems of reliability but they can locate from long distance.
Except if some people of you wants to write here again the same and same things. If so OK .... we will stop to write here and Carl can delete the remote sensing (there is not other reason to be here).
Or Delete us
Bye

Hi Geo,
it's my opinion, you can have your opinion different from mine. Not the point.

I said that cause I've seen many different bought units (different models/brand) on the field, in action, of friends and other people I know: no just one of these were capable of find anything.

All re-sold them very quikly cause of the bad feelings related to the fact no target were found with those...total waste of time and money.

I, myself, built the zahori circuit with my hands, tested and found absolutely nothing in places where with metal detectors I found after ancient, long time buried metal objects.

Not only: circuit doesn't detect water flows too ! And was claimed do that.

What must I think of all these things now ? That they work !?

Your experience could be different from mine... ok... why not ?

Then I'd like to see these Andreas or whatever manfacturer unit be tested in a scientific way, like in the challenge... and win in front of a TV camera.

Personal impressions are good to take personal conclusions... but just public demonstration can solve any dubt on the topic.

Untill that I'm free to say:

Geo, you're right.

Or Carl open an exclusive thread for real discussion with real rules without any type of insults or criticism against the work of others.

If somebody failed at first time in make operable an electronic LRL, this is not reason for to discredite. Also I build several MD doesn't work, and maybe the error was mine, maybe not, etc.

Also I failed 1,000 times in build operable electronic LRL, and know several ways that it work.

Esteban
