New detecting method?

[g-sani]

When, in disgrace with fortune and men's eyes,
I all alone beweep my outcast state
And trouble deaf heaven with my bootless cries
And look upon myself and curse my fate,
Wishing me like to one more rich in hope,
Featured like him, like him with friends possess'd,
Desiring this man's art and that man's scope,
With what I most enjoy contented least;
Yet in these thoughts myself almost despising,
Haply I think on thee, and then my state,
Like to the lark at break of day arising
From sullen earth, sings hymns at heaven's gate;
For thy sweet LRL remember'd such wealth brings
That then I scorn to change my state with kings.

Willy Shake (S.29)

Nice poetry WM6 but I never herad of Willy Shake.
Was it a treasure hunter as well?
Not a dowser anyway!

Hi g-sani,
The Magnacast 5000 is said to be an AM transmitter using a loop antenna to send a signal to one side. Then a second small receiver loop is held in the hand to locate the hidden metal. I heard no information to show that the Magnacast 5000 works, or not works. You can only know by trying it to see. Forward Gauss does not mean anything. No electronics engineer or scientist has ever heard of forward gauss. It does not exist. This is only a word made by the manufacturer to make it sound like it is new technology. Also, I do not believe you will find multiplexing circuits inside this detector like the manufacturer claims. But I don't know for sure.

I would not spend money for this detector unless you see it finds hidden treasures first. The other detectors built by VR Electornics are believed to fail for finding treasure. Even Dell Winders said "...operating conditions deteriorated affecting the reliability of the instrument making it impractical for my use in 1988".

You can read more about the Magnacast 5000 here, where Dell Winders posts false information and tries to hide the truth about forward Gauss: http://www.geotech1.com/forums/showthread.php?t=13089

This is what I thought to be J_P.The rest of their detectors have nothing special to show.
Of course the same thing applies here.Try it yourself to get knowing the truth, as always.

Hi WM6,

I made it before 2... 3 years. I tested but i had problems. It had the ability to detect a big object at 30m but it was very sensitive North horizon, at distance between me and detector and from trees.
So i let it at the side .
Maybe at lower frequency to work better .... who knows.
I don't remember sure, but i think that it worked at about 800Khz.

Geo, are you tried to put your ferrite antenna in RFI protective housing made from can of beer (one side open) and connected to ground of oscillator?

[Krzysztof]

Hi Geo.
It issues me, that secret sticks (lie) in (to) in antenna with vertical magnetic polarization.
So as vertical feryt, we search something better.
And f max< 32kHz.

Hi Geo,

you are main developer here. Are you done some test?


Yes Krzysztof, it is more clear to me now, what you suggest.
Except draving Ad.4: did you imagine RX or TX coils as a fixed scaning or mobile?

It seems to me that many of you here know the tips to build an LRL using rf (Tx and a Receiver to go on target)
This theory is already proved that it works and all you electronics should have one ready in your home for your treasure hunting expeditions.
Instead of that you are looking for other ways of building LRLs when you never had any treasure discovered yet.
Forgive me but I don't understand you.
I remember Esteban said that it is working and I think also he put a very old pfoto somewhere of people using it back in the late '30s.
Well I will put it down again.
I used to owe once something like that and I said it before in some other thread that it was working allright.Some people don't believe me but what can I do about that.
I said to Geo that sometime I will give him the Rx(which I still have) to see if we can make a suitable Tx so to make it work again.
You see we placed it once underneath a tree and we took the Rx and went a bit far from the transmiter while trying to spot a target.It was raining heavily some hours before and water drops was coming down from the leaves.The result was a short circuit at the Tx and it stopped working.We sent it for service but...
They sent us a different LRL back telling us that they could not repair the Tx.I loved that LRL and I was upset when we received back a different one.
Anyway, this one works as well but now you have to be a bit of a dowser to go on target.
To tell you the truth I wouldn't mind of paying some money again for such an LRL and if anybody knows anything in the market please let me know.
Does anybody knows if MAGNACAST™ 5000 FORWARD GAUSS Metal Detector™ works on the same principle?

Hi of all.
I don't think so , that we're to clear forums as well bids of unfamiliar utilization present techniques not abnegating sie the old man vets. Yourselves ain't dowser , Respect those regular people whereas not swindler.
I not know gold gun , I think not , everybody they've entrance into nich as well wherefore bids of unfamiliar coinage DIY.
J_Player g_Sani.
To be sure best antenna is not they've big storing magnetically clearing switch pawn as well least radiation electricians over world ; 60 years before the communication was done ex antenna underground on figures 2 probes tributary margin ex generator engine-room undersized frequency communication (besieged troops ).
Wherefore coinage ex signal electric ex generator Tx until world is not worst.
J_Player.
Zone LF this dubious coinage. Exemplary transmitter Monte Carlo (225kHz, 200kW) premises (interference) transmitter Warsaw (227kHz, 1MW) heard on Nand France free past distances upwards of 1000km to automotive receiver wireless.
Wave worldly-minded superficial is not large what prompts breaking signal aims.
Yesterday wrong frequency quartz ex timepieces duty be 32768Hz.
I don't think so , that Tx generator to quartz 32kHz at least on often Tx clearing us ex the rubs and worries of life of stability.
WM6.
Account spool Rx clear mobil until scaning. Spool blanket 1m x 1m will correspondent , not refutes of utilization spools on the lines of MD average 30 - 40 cm , whereas depths yet never mind.

Yourselves deal to spring coinage ex Rx on figures gradiometers fluxgate ( tenderheartedness some nT/m )- this so-so promisingly.
At least once EMI will be utilization.
Bids until tendering your coinage.
Best regards. Vy 73! Chris.

MikeBG,

This is true. What I would rather use is an active antenna to pick up the reference signal and compare the phase of the ref. signal with the signal from the horizontal loop over the treasure or ore. Another idea that I've seen in Magnetotelluric patents is to observe spectrum in the audio range when you are over ore deposits. For treasure you would use higher frequencies to see the smaller objects. In lieu of that you could use a white noise generator to do the same with much better S/N for the same spectrum signature of different metals or ores.

AL 707 and AL718

AL707 and AL718 are very primitive and imperfect compared to EM16 of Geonics, because they have no a second ferrite rod antenna for reference signal. The operating principle of EM16 is described in patent US3500175.

Hi Geo.
It looks like a mini two-box.
And I think the 2 antennas with a vertical magnetic polarity, the land
component preferably disperses component magnetic field the electromagnetic field.
Maybe someone is thinking of something better than the ferites
antenna.

Hi all.
Modest note attached.

Unchecked idea is to use my Fluxgate magnetometer as an Rx!
Always treated the VLF and the other as EMI, now you look at it differently.
Tx antenna gives the issue a magnetic field, propagated in the ground, when it is sufficiently stronger than the earths magnetic field in conjunction with GPS and "Vumate" or "Snuffler" we are better than many well-known German company.
Who else will join the storm drain?

Hi, WM6, J_player.
I have some ideas for discussion:
1. Tx antenna should be the characteristics of a vertical magnetic. For example, a low power 10mW may be an antenna coil structure feryt of basketball (max Q) upright position (at the high power nature ferytu turn into a piece of wire). Maybe some other magnetic antenna Slit (but size - it could be a bad idea) . I think that 1/4 lambda antenna or coil, has a large vertical leaf levels of radiation, and we do not want to receive the signal reflected from the surface only goal.
2. Can benefit from the popular timers 36kHz quartz and pure analog generator to minimize the distortion and
harmonics. Rx side, you can think of crystal ladder filter with the same X-tals
3. I think that AM 500 kHz bandwidth makes for great Skin effect (more superficial than deep). In addition, A3 gives random modulation signal strength at measurement. Any modulation of A1, A2, A3, A3A is amplitude modulation, which forces a large measure of time - averaging.
4. How about an antenna Tx / Rx Framework 1m x 1m placed horizontally 20cm above ground level to eliminate the capacity of the soil (detuning) and reduced mutual visibility (direct reception)
5. Do you not think that we are moving close to the technology 50 years ago and described by Mikebg in this forum?
