Kudos to bro GBoy, if you would like to test somebody else dowsing equipment or metal detector, invite them on some place or at some inconspicuous location (not at your proj. site) but before you conduct the test bury some gold metals about 1 foot deep or less in 2 places 7 meters apart then ask them to scan the area starting 14 meters away from your buried gold metals let them sweat their ass out to test their ability.
I've done this testing many times sometimes in my own backyard and not even burying any gold metals. I do this test specially to the dowsers who use German sticks or any other type of rod and sometimes to metal detector user.
I tell them a story about a missing well somewhere in my backyard and from that story they start their dowsing or detecting process, they come out with even bigger story pointing to spot they detected but never single one of them found what I buried and not knowing that the location is empty and the story is just made up.
After a while your place become a legend TH come and go to your place believing that there is really something big out there, suddenly TH knock at your door begging to scan, dowse and dig your back yard some even suggested to dig a tunnel going underneath your house. Even some old folks joined in from nearby places, they hang outside your property telling stories during Japanese time that they were there when the Japs sneak in some 2 or 3 small drums in a well that was there before. The story was like a wild fire it spread attracting TH from as far as the North and up to Isabela. But I never allowed anybody to dig. I only use this place for field testing and never did anybody ask a single centavo.
One day some 10 years ago an old guy from up far north suddenly appeared with treasure map, he convinced my uncle that there is something in his property (I was long gone in that place when this happened) they dig his front yard they said they found the marker, then they tunneled under his living room after milking my uncle with his life savings they ran away. I was furious why he fell from their scam I got the guys CP# invited him to see my place but he sense that he will not survive if he will do it. We just exchange some bad word and warned him not to venture in our province. My uncle never recovered from that incident he died a pauper and almost lost his house.
I realized latter I created chaos in our town many TH come and go, neighboring property have their own stories, Catholic and Aglipay (the first Aglipayan church in RP) Church, Elem. School and High School our town plaza was not spared, our town Mayor and others have their own sites to dig. And worst of all the ancestral home of my lolo was bulldozed the old Spanish house and 2 big ware house was gone completely, people told me that the Provincial Engineer and the town Mayor sent gov't heavy equipment to dig the entire property, they dynamited the underground tunnels and left nothing standing.
Our property, the ancestral house my uncle's is all located strategically with the town plaza in the center, North is the 2- Elem school, East are 3 big properties with spanish houses, South is our property and the Municipal Bldg. and West is the big property of our ancestral home. All these properties was captured by the Japanese our house was said to be the gambling house of the Japs, the ancestral home with 2 big warehouse became the head quarter and prison house.
The bottom line guys, from many many years past specially after 1986 a lot of fairy tales stories came out it spilled in the country side, during the 70's you can't hear a whisper of YamTres then early 80's mountain tribes join the frey, after APO FM over throw it became free for all, I was even amaze people as young as 14 years to 25 suddenly became an expert. At early 1990's Metro Manila became the breeding ground of scammers coffee shops and malls was their favorite ground. Then mid to early 2000's Fake Gold bars surface, legendary tunnels full of gold became the story, scammers spread out reaching Pangasinan to Batangas, and from then it became a fever that it spread all over the country.
I met a lot of these early scammers in coffee shops and corner malls from Pangasinan, Tarlac, Pampanga, Cavite and Batangas I met them face to face, some where military and even met Datus from Mindanao offering their caves full of Gold.
As I can see from forum to forum a third generation of TH is creeping up. More sophisticated than the previous but most or almost all of them lack common sense and very aggressive.
Just what I have narrated tell a story and these 3rd Gen TH will come swarming like flies.
