Good idea, WM6, we can send them with an atomic unterwater-boat to those locations.
Of course if it contains noble metal it would be detectable with their LRLs from 1000s of km...
btw. I guess we have already their approx. distance values -
because this forum since a long time is full of them!
And all those values are far too high for being real practicable:
small stuff 10 meters and for larger 100 meters or even 500m to 1km.
Didn't found that Mineoro guy this little golden jewelery-thingy from 20meters?
Of course we know already this was some nice little "magican-show" but if it would
have been the pure and fantastic truth it would be even more devestating!
In other words:
Those LRLs have no selectivity!
They even can't reduce their sensitivity so it would be possible to pinpoint their
"perhaps and maybe selffound" things without a metal-detector as a pinpointer.
At least some cross-pinpointing from a larger distance must be working on a very small angle.
This means if the coin is 15meter away and someone wants to crosspinpoints it,
this has to work like shooting a bullet with a gun - the LRL must show through a
littel telescope into the absolutly exact direction where the coin is below somewhere.
Otherwise you can search forever for it, if the "detected area" is like a huge elipitical
cloud with a size of 10 x 30 meters for usual objects.
The more hard facts and good arguments we collect here together,
the more their "LRL-theories" and shiny treasure-detection-stories
fall into little worthless pieces like a x-mas-bauble fell off the tree!
