Beware the LRL, MFD and Eye in the Sky
The market seems to be flooded with Long Range Locators of one sort or another. This along with so called map dowsing and the fellows out west and down under that claim to be able to locate treasure via aerial photos.
Years of testing and proving have proved that none of these so called devices or systems work. I've had map dowsers tell me the GPS coordinates of a box of Spanish gold coins buried at 33 inches or another long range operator try to lead me to a cache of gold bars with specific details as to the total weight, type of container it was buried in and the depth. Interesting that never was anything recovered.
I have even asked them to run tests on caches that I knew about, investment caches of gold that I had put down for safe keeping and of a sudden they are now no longer able to determine amount, weight, depth or even exact location, a margin of error several hundred feet in diameter so they say yet all the while I knew there was never any gold in the area.
My final test was to actually place several pounds of scrap gold in a specific area and let it set over a period of years, sometimes I received word that nothing was there or received a pinpoint of the exact location which never coincided with the actual burial place of the cache and most times from several different "seers" received several different locations none of which were the spot. They all speak of "finding" one thing or another though none ever claim a recovery. They can all tell you where it is, what it is and how deep it is yet, they never go themselves to check it out.
Conclusion, nothing circumvents hard work, sound research and time in the field with a unit that blasts a signal into the ground and when reflected back reads out whether digital, analog or merely a sound. The metal detector works, it knows when a metal object is within range, the other stuff is merely snake oil, witchcraft or wishful thinking.
Stan's response: Unfortunately, in over 40 years of trying and hoping, my experiences have been the exact same disappointment that you describe Dani. I've always tried to keep an open mind in dozens of attempts, but not once did LRL's or dowsing (including maps and photos) ever work out.
