Gravimeter capabilities, treasure cache?

[Gunslinger44]

Is anyone here familiar at all with gravimeters and their resolution or finding capabilities? For instance, would a gravimeter be able to find a cache of silver or gold about 3-5 feet under ground? What kind of survey increments/grid spacing? Also, any info about new gravimeter tech such as the Wee-G?

I just thought of this because there is an alleged cache site I have searched, and I read about the Dent's Run, Pennsylvania lost Civil War gold story, and the survey company brought in a gravimeter, the results of which were so extreme that they got the Eff Bee Eye involved and said agency may have stolen the gold, but I digress

A portable gravimeter isn't going to detect a cache. Sounds like someone was writing fiction, probably as part of a con game.

OK, you are speaking from knowledge, experience, or what? Do explain, because your statement that the gravimeter findings in the Dent's Run gold is "fiction" is absolutely retarded. It's well-documented that the F Bee I were up there on the dig, and that the original treasure team were kept in the car while they were digging, they had several trucks come and go, then it abruptly ended and said agency said "we found nothing, time to go home", the treasure hunters are claiming fraudulent activity on the gov's part and rightly so.

Well, GS, sounds like you agree with my post.

Allegedly tons of gold? No ordinary cache. Maybe with differential gravimetry it'd be possible? But that's separate from the question of whether or not people lured by stories of lost treasure (think maybe $100 million worth) always tell the truth.

Whether that would be relevant to the cache you're thinking of, that's another story. But what the heck, you're the one who's interested and you've got the Internet! The manufacturers of the equipment publish the spex. The rest is middle school general science and algebra, and knowing how to use the equipment. So no need to take anyone else's word for it.

Gun, the Finders-Keepers guys use LRLs in their searches. They're what I call Big Time Treasure Hunters. People who hunt pretend treasures with pretend devices. It's almost a guaranteed certainty that they found nothing at all. And if a legitimate gravimeter survey was done it would not have the capability of distinguishing buried gold. Maybe they meant they did a Gravitator survey... I'd believe that a lot more. Anyway, if the story as told is true (and I'm not convinced of the telling) then the FBI behaved oddly. But it's otherwise an entertaining make-believe treasure hunt.

[Gunslinger44]

The FBI thought it sounded real enough to bring about 50 agents down there, backhoes, trucks, etc. They hired Enviroscan of Lancaster PA to survey the alleged cache location, Enviroscan used a gravimeter/gravitometer and said yes there are several tons of high density metal there, likely gold or silver. No mention of LRLs, not by Finders Keepers or the Feds, but every article most definitely says a gravimeter was used (likely among other instruments).

http://www.enviroscan.com/home/ looks like a real geophysics company.
Still haven't heard a credible assertion that they located the alleged cache using gravimetry. Or for that matter that they claimed a successful locate at all, only that "someone" claimed such.

GS44, if you don't understand how much BS flies around lost treasures and gold, and disbelieve everything you hear until substantiated, you're not cut out to be in that line of endeavor.

[Gunslinger44]

All the articles state that Finders Keepers guys found the location with their own metal detectors, whatever those may be, could be LRL's or divining rods for all we know. But it does say that Enviroscan specifically used a GRAVIMETER to confirm the location as containing several tons of high density metal. Which is what I've been saying this whole time. Now, my question to you, which hasn't been answered, was by what authority are you saying that finding a cache with a gravimeter isn't possible? Do you have training in gravimeters? Read up on them? Ever used one, what? From what I have read there are a new class of gravimeters which are much cheaper and also much more sensitive. I'm not looking for watering-hole speculation here, but for answers from people who are familiar with the instrument known as a gravimeter.

GS44, I haven't seen any evidence that Enviroscan did a locate with the gravimeter, only that a gravimeter was among the instruments they brought. And I already said that if we're talking tons of gold, not an ordinary cache, maybe a good gravimeter would find it. Therefore maybe one did. The whole damn thing is irrelevant anyhow!

So you're interested in finding a cache. If you want to know what a gravimeter will actually do, it depends on which gravimeter and how you're using it. So rather than just trying to bait people with nonsense, and then complaining that you don't like their answer, here's a plan for you.

1. Go to the websites of manufacturers of gravimeters.

2 . Read up on how gravimeters are actually used.

3 . Figure out which ones interest you.

4. Read the specifications.

5 . Calculate the gravity anomaly of a hypothetical cache that's representative of what you think you're looking for. Middle school science & math.

6 . Then calculate will that gravimeter properly used, detect that cache? Middle school math.

"...The FBI thought it sounded real enough to bring about 50 agents down there, backhoes, trucks, etc..."

This reminds me on similar happening here, i think in late '90s.
State army, special forces and secret service were engaged in similar few weeks lasting survey.
My hair went straight up when heard the details.
As a sane (presumably) man; i would always look up for the unbeatable evidences and perform several months investigation and series of deep analyzes: before even think on engaging state institutions for such lunatic undertake.
Yet they did all relying on fairy tale, told by couple of senile lrl'st. One of those was related to high state politician (army man). So it was no effort at all to "press a button" and start major action.
Again... my hair went up...
Two important questions from such stories;
1) Are there any valid evidences of existing "fortune"? Any written trace, papers, documentation?
2) Do we realize the horrible and sad fact that we are leaded by total charlatans, holding the whole possible power in our states?
Fact that FBI was there; becomes irrelevant and powerless, having in mind that there is huge chance that chiefs are also charlatans, picked and put there by charlatan politics (maybe exactly purposely for that reason).
So; commanding chain is like that: on the top there is charlatan with the fake diploma, holding all the power and pulling all the strings. Prone to charlatanism, improvisations and dirty business.
No matter the fact that FBI is reputable agency with a highly educated staff; it is still only a "tool" in hand of politics. And if we have total charlatan on the top, pulling the strings... everything is possible!
State budget money is wasted for other much more insane reasons, so why the hell not on this too? As long as there are citizens to pay the taxes!
Considering all this unbeatable truth; there is no wonder even if Mineoro was used in such undertakes.
Actually; i am ready to place a huge bet that there was Mineoro there too!
Probably hidden in one of the Suburbans trunk.


In such stories it becomes totally irrelevant whether the "gravimeter" can find the treasure or not!
Simply because there is no treasure at all!



All the time having in mind this question: "..For instance, would a gravimeter be able to find a cache of silver or gold about 3-5 feet under ground?..."
If we speak about the "deposit" and not only a single gold coin; ANY better PI will do the job!
You don't need the "gravimeter".
But if we speak about the single gold coin; not even FBI, NASA and CIA put together will do the job!

[dbanner]

Yes, I agree. What utter nonsense. There are high density underground deposits on the moon. Just ask the Chinese. Anomalies exist every where on planet, and is certainly not beyond the realm of possibility of huge gold and silver deposit in underground vein being so detected, problem is the science doesn't back it up. When the men in black show up, then you can be assured that there is folly afoot.
Pseudo science is lucrative business. Like free energy of Tesla for left wing green energy fruitcakes.
You can increase resolution of gravimeter all you want, problem is gravitational waves gradients exist over a wide geographic area, making small anomalies in density undetectable. However, mapping underground landscape over a huge geographic area is standard science.

"..folly afoot..."
That was the term i was looking for!
Oh.. my English is so poor!

Ivconic, thanks for your very cynical outlook. But I've done tests on target caches at 3-4 feet down, and found that no metal detector from VLF, to 2-box, to deep PI will reliably find it, there was even a very long thread in this forum with many people attempting the same type of thing, with very disappointing results. Finders Keepers (the treasure team in this story) stated that the FBI hired Enviroscan to see if anything was there, Enviroscan (an actual geo survey company) confirmed the presence of a large mass of high density metal there using a GRAVIMETER. Its not out of the question the FBI being incompetent, and the treasure hunters being *******es who found a "target" with an LRL, but that Enviroscan specifically said "YES, there are literal tons of metal down here" and then there's nothing? I don't buy that.

Dave J.

You could have saved us both a whole lot of trouble by not posting an ignorant reply to begin with. So you have NO experience or knowledge of gravimeters, and you decided to tell me its impossible anyway. Fascinating. Then you tell me to go research gravimeter specs online. Hell, why does this forum even exist? The whole forum should just be deleted and a big text that says "go do your own research, use basic kindergarten math, etc".

Sorry i was not intended to be cynical about anything on this topic. It's just interesting story that reminds me on similar one that happened here in late '90s.

And i see certain misunderstandings here too, please understand that:

1) "...large mass of high density metal.."
2) "...on target caches..."
3) "...literal tons of metal down here..."
4) "...a cache of silver or gold about 3-5 feet..."

ARE NOT THE SAME THING, not the same target.
So... i was referring my observations rather on something which i imagined as quite large and consistent target.
Not precisely a "...small box of modern coins, buried there few years ago..." as it is the case at "cache test" from the other topic.
It is quite misunderstanding referring the actual target; won't you agree?
My advice would be; you first to decide what exact target you are interested in.
Than you can expect more concrete suggestions from other fellow members here.
No hard feelings upon this.
Unlike Mr. DJ; i really enjoyed reading this story from posted links!
Fun!
