Oak Island and LRLs have some astonishing similarities:
Both costs alot of money, claim to bring gold or the big treasure while there still doesn't exist really reliable evidence or proven scientific test-experiments.
With LRLs and at Oak Island alot people dugged really deep holes and found - nothing!
And in both cases there exist fantastic lores or tales about huge treasures.
btw. I found a nice search & click adventure called:
Mysterious Worlds - The Secret Of Oak Island

Curiosity - you also get some "LRLs" in this game!
I'm personally just wondering how "crazy" people really are, still not knowing after 200 years if somewhere is a treasure or not!
If it's really a sinkhole with underneath caves geologists already should know for shure so they can stop bumping more and more billions of dollars into a "treasure-hunt" that never pays off.
Same with LRLs. How long do those already exists and how long does it still take until there is a proof or not?!
If there really is a measurable effect of long buried objects that also enables usual MDs finding them much better and deeper - like alot MD producers claim! - there should exist a scientific way to isolate the surrounding soil or whatever for chemical or electromagnetical field tests.
If the soil gets "metalized" (like magnetised iron near a magnet) it must be measurable.
And much more easily for any electronic engineer it should be measurable what a detector really detects or not!
Take the device apart and check out electronical stage per stage on what the circuit reacts or not. I doubt those use unknown receptor-units.
And into those "super mysterical" Oak Island I would have dugged a tunnel with massive walls so that water and mud no longer would have been an issue.
And if there are only underwater caves below some divers already would know this for shure now.
You really have to go the systematical way if you wanna get authentic information. Put stuff completly apart and not just half. Search for everything and everywhere and not just here and there a little bit.
As long as people don't wanna learn these simple principles it is completly their own fault if they fall for tricks, fraud and all kind of stuperstitious storytellers!
