That's a short range locator (several centimeters), not an LRL. The cheapest metal detector we manufacture here in El Paso TX (the BH Junior, about US$60 retail) will detect a ring like that in air out to about 10-15 cm, and we have other metal detector models that will air test a ring like that past 25 cm. Not only that, nobody disputes whether real metal detectors work or not, the disputes are over how well they work in certain situations.
This is very different from "LRL's", where nobody's identified one yet that can be demonstrated to actually locate what it's supposed to locate without fakery, and the people who sell them can't even agree on how they work. See the 10 Hz thread for how silly it gets, I tell people how to buy a 10 Hz transmitter and receiver system that actually work, and they refuse to talk about it! Meanwhile one guy insists that if a fellow in Eastern Europe can make a pan stick to his forehead, that proves LRL's work scientifically, did you follow that line of reasoning?
Meanwhile back to the video you've linked, here's how funny it gets: a guy who says he's got an LRL (!) is proudly demonstrating in a video (!) that it can't see a ring farther than several cm(!)
Through fantasy, one can pretend that cm's are km's, but the real world does a poor job of obeying the fantasies of mere mortals.
