hi Randy
as you say this device is sold as light meter.there is no claim say this can detect gold.
but a friend of mine say this device detects gold.
he saw this at a friend.and they went to some trips together.and his friends searched area for gold and pointed.but while using device he does not let somebody close to him.
my friend saw device from distance .and we searched a lot to find this device.
user of this device is known because of his finds.he is rich.he found few big founds according to my friend.

Gold vs Silver IR Spectrum
Esteban,

I was looking on http://64.143.63.33/pdf/coatings.pdf
and on pg. 5 they show the spectrum Graphs for Gold and Silver and radically different. Gold is at 95% at 900nm and 98% at 10um whilst silver is 95% flatline from 600um to 2.0mm. You can buy a inexpensive Far Infrared bolometer that covers 8-12um which is around what 80 to 90 degrees farinheit? I have one at home that I bought from J.P. Marlin mail order (type in google) for $3.50 I believe. It's been several years and there's also a company that has a kit that enhances that bolometer. If I can find it at home I'll post it. It's fun device to play with and so easy to use with a minimum of parts.

device only detects gold and copper

[Esteban]

The good conductive metal causes alteration in main beam of IR ray, but why causes this? So, modulated frequency (audio range, wich trave in the IR beam) changes his patterns in hertz and you can detect the metal.

The IR beam is very precisse, very pinpointing.

Remember: IR actuates as antenna. The IR light (of a simple IR led, for example) ionizes the air and hot his way. With IR you can "see" (or detect) more. Here a example of how IR can show more:

Hi Okantex

I search for Leningrad 7 in the web. There are models Leningrad 1 to Leningrad 10. Leningrad 7 uses selenium as light sensor, maybe this is not very precisse in order to measure quantity of light near IR radiation, but the most important in this case is the sensibility.

But if you wish detect IR radiation from the soil, you can solve the problem with IR receiver module for remote control TV. This is into a small metalic box. I experiment with it and promises very much. You must insert into a obscure tube, no black, because this bright. Better is darken internal paint into the tube.

Esteban-pyroelectric detector

Esteban,

I finally found the supplier of an inexpensive pyroelectric sensor and fresnal lens. Goto: http://www.glolab.com and check out the specs on the PIR325 and FL65. Each item is $4.ooUSD plus shipping and there is a really nice applications manual for the PIR that you can print out.

Could you email me your email address? r.seden@sbcglobal.net

do you have it in your archive.
I would like to read it all.can you help me.
I can sent my mail through PM.

thanks mosha

OK, Randy, thanks very much.

Found a paper for detection at THz region. See the tip in contact with the positive electrode of photoconductive THz emitter based on GaAs, this is base of simple IR leds. Coincidence?

Hello

[Morgan]

Hello TH´s , I´m new here,and try to find how this work.

OK, Randy, thanks very much.

I have a new Mineoro LRL,and i want to talk about my experience with this machine.

I have a new Mineoro LRL,and i want to talk about my experience with this machine.

Please go ahead ... and be honest in your opinion of the Mineoro.

Test with Mineoro DC 2008

With my respect to Mr.Damasio the inventor...
This test was made in a field where was buried 20 years ago a GOLD medal to test performance of TR/IB metal detectors...

[Morgan]

Testing DC2008 Mineoro

Before some people in Geotech Forum think or decide to buy any kind of LRL device,remember there is a place on this planet where there is GOLD buried some years ago,NOT TOUCHED FOR TWO DECADES!!!
I can´t say Mneoro not work,i only want to tell to Forum my experience with this device,and the results of more than a year of searching with this LRL...
Finaly i get my conclusions about DC2008,and decide to tell the performance of this expensive LRL.
