Can metal transmit signals? I would think yes but how useful those signals are for detection by various practical means is the big question.
Atoms have electrons and metals are good conductors and I agree with Esteban that larger metal objects are easier to detect because of their extra mass.
I have an old TR detector and it will go surprisingly deep on large objects but much less on small objects.
OK, I am still skeptical of LRLs, someone send me me a working model -free- and I will check it out....but don't bother though with the mechanical type :D........those with a built-in BFO, I will give room that they might work.

Theseus,

Do not post another member's personal information without their consent. The rules of the Geotech forums (and this forum in particular) include the following:

• Be polite. Write messages as if you are standing in front of someone talking to them.
• Criticism should be relevant and constructive. If you disagree with something, state your case, and move on.

Stick to the topic of discussion, there is no need to get personal. I've known Randy for a long time, and even though I might disagree with him on some points I can say that he is looking at all this from an inquisitive standpoint, and has no agenda.

Randy, I only use standard type detectors so I would have no idea what frquencies would work for prospecting, if you mean a passive type electronic device.
If you are referring to VLFs for prospecting, you probably have an idea, looking at what is for sale on the market, higher frequencies for small stuff and lower freq. or pulse for larger items.
Perhaps Esteban and others have figured out a method using BFOs with various antenna configurations, I would come closer to believing the possibility of this working over pivot point devices, that would seem to be more challenging as far as successful operation.
As far as circuits, I am not a electronic builder.
I look at this from a standpoint of how practical something works.
You mention being able to pick up signals from small gold thru means of passive devices, that would be great, if ground signals can be screened out or ignored.
I see where the mention of using a FM radio as a receiver, the higher the frequencies get, the shorter the waveform will be and I would imagine their usefulness for treasure hunting would be questionable but hey, maybe someone can mod a cell phone to pick up emissions from the ground?
I read somewhere that the military has a vehicle that can look into the ground and can tell the diff. between pulltabs and rings, probably anything else but it is necessary to wear a lead suit while operating.
The cost would be out of the reach of anyone except gov.
Large gold is not of interest to me, if I knew where some was buried I would
1 Buy the land
2 Get a very powerful PI with large coil(s)
3 Get a backhoe and sluice and start digging:D.
Regards.

Natural Background Radiation
 

Sorry. Randy made more than one reference to me that I had him confused with someone else. I was merely trying to enlighten him (prove to him), that in fact I did know who he was and was not confused. As Randy pointed out, I did not reveal anything about him that was not already in the public domain. Hopefully, this thread can get back to "the LRL frequence(sic) of Gold". ....and thanks for the reminders.

Incidentally, I re-read some of Randy's earlier posts to me, and I'd have to say they no doubt fell outside the scope of "polite".

What makes you think that Max was banned? :shrug:

Was RObert!

Max was Robert! ???

I think Seden mixed up Max and Robert.
If Max was Robert we would know it :razz:

No, the banned (s) was RObert and Sony. Do you remember? Now, in this "new" forum don't appear as banned (the both).

Seems... are des-banned. :lol:

Don't know what happens with Max.

Robert the banned
 

Ummm... yes Robert did contribute some technical stuff...
If you recall, he contributed the circuit for the "Robertoro" LRL...
Which led to a series of photos that I submitted showing my construction efforts, and the difficulties I encountered at the beach in the way of distractions that kept me from my second favorite hobby, building treasure machines.

Unfortunately. these photos were removed when Robert was banned.
However, through a miracle of electronics, I am able to re-post the photos showing My construction efforts with the "Robertoro" LRL, and the distractions at the beach....

Too cool J_player!
 

HI JP,

Your pictures brought me some memories too, the soldering iron you show is very similar to my first one, i was 10 or 12 and this was the only way i got to solder my first components.
The only difference is that i used a small tube (from a pen or something) to bring the gas farther and close to the tip.Of course doing so i needed another lighter to "ignite" the system...
AND, i was already getting girl´s atention too. :razz:
Regards,
Fred.

These forums aren't just for electronics, but metal detector electronics. If my math is correct, statistically there are only 6 women in the whole world interested in this, and one of them works at White's. So where are the other 5?

I think Max is in a part of the world where there are many political problems. Many he's located in the Gaza strip. :frown:

Long Range Detector
 

On eb*y right now there is a long range camera that states it can find near surface gold using post processing. Company is out of Australia and is there any input on these devices? Are they bogus?

You can also see the gold location on the screen as you walk. You don't need to take a shot until enough gold is visible in a certain form. Sounds hard to believe but it's actually the first device that allows easy-as-carrying-a-camera x-ray below the surface. It's two-dimensional but answers your questions fully. The bottom picture on this page is a stylized impression, but it works!

This is a scam run by "Ranger-Tell", a.k.a. Vincent Blanes. He's selling several scam devices on eBay. I own 2 of his "Examiner" LRLs and they are an absolute joke... a calculator taped to a dowsing rod.

- Carl

OK. Carl posted his impressions.
Now I post mine.

I own the RT examiner and it worked for me. So much so, that I found that their aproach is just a tip of the iceberg containing tons of info and possibilities. Their aproach is just a seed that led me to develop a full electronic and powerful LRL system.

The first thing I found years ago with the RT examiner was a silver ring. Then came other more 'valuable ' stuff.

Try it and decide for yourself. Don't take our words. It will either work for you or not.

About the maxfynd camera, I don't know if it works, but the concept is true and I'm working on the same technology right now.

Regards.

Hung is right, don't take our word for it. Contact the seller, ask for references of people who bought the product and actually recovered something with it. Call them and get a detailed report of what it does.

- Carl

Earth to Hung! :shocked:

You are either seriously technically-challenged, or part of the wallet mining brigade.
The RT-Examiner is simply a very poor attempt to deceive those with minimal or no technical knowledge. No one in their right mind could possibly believe that a cheap calculator taped to a swivel handle could detect anything but gravity (and occasional wallets). And don't tell me that I don't understand the physics behind this so-called LRL, as I wrote the spoof article of the RT, that you sent to Ranger Tell, and they actually posted it on their website. How gullible ... just like their customers.

Same thing for the camera, if you look at the feedback you will see positive one only for usual stuff,and the less positive one are "private".
aparently is´t just a $200 camera with a ir filter sold $800.Then they use the autofocus thing to "spot" places.
It appear more and more obvious to me (Yes Mr Q ) that any random signalling device will work fine for LRL.

First of all I'm not involved with RT (or any LRL corp) either technically, financially or whatever.
I agree LRLs are priced unbelieveably high. The present RT unit can be built for less than $5.
But if LRL manufacturers include their developed concept in the final price, this could justify the increase in price. But not at the present values which are displayed over the internet.
In the case of RT, the increase in price is due to the main elements of the device which are the table of frequencies and the equations to be input in the calculator to make the functions work.

Secondly, a calculator glued over the antenna is inducing the circuit. The calculator is the signal generator, and every amateur engineer knows the calculator value displays in the LCD input frequencies. If some here refute that they need to be aware of it as their ignorance escapes common sense.

Third, according to RT's site, they hit more than 3,000 customers along the time. Imagine 3,000 anggry customers rioting in front of RT' place. They would have probably burned the house down by now and you would have known about in CNN.
So, don't come with this non sense talk that it's ideomotor or t's a scam. These statements are the true BS.
I know many RT users and they confirm it works and their findings.

Last, I don't know if the camera works. Could be trough infrared, or something else. Fact is this concept is highly plausible as I know now.

Regards.

If it was actually involved in the "finding" of a target you were looking for; all that proves is that a bent coat hanger would have found the same target.

If you actually paid for the Examiner, and didn't receive it as a gift in return for pushing it here on Geotech, then you have been the victim of a grand LRL hoax, like all the rest who bought that worthless contraption. :)
