As we watched, he got another instrument that was similar (but yellow) and looked more like a cane without a box on top. It didn't do anything that I could see, and again he seemed frustrated. He went back to his truck and began calling someone.
When he came out, he had two copper rods in the form of an "L" with the part he was holding in some sort of tube. I think the tubes were acting like a bearing. He began walking very s l o w l y along the footpath holding them out like a pair of guns. I watched close as we followed him and what I saw next stunned me....I saw the rods move toward each other until they faced each other. At that spot, he sprayed some paint. He then went back to the truck and got the "metal detector" and came back to that spot.
It didn't beep, but I think he knew where he was going now, and as he walked a few feet, the instrument began a high pitch sound...he drew a round circle with paint, then the letters "W/E". My friend asked him more questions and he said they all have those rods. When he showed them to us, they looked professional, not like a cheap pair.
I'm a little shy talking to strangers, so I called my dad and told him what I saw. He laughed and said the guy was just joking and dismissed it as a prank the guy was pulling on us. I don't think so. He looked dead serious when he was doing it.
I looked it up on the web, but there are many pros and cons.
Later that day and today, my friends and I made some, from different materials, but can't get them to work
I understand the operation of the magnetic field in the metal detector, but not the rods. What is the process. (or were we conned).
