They "found" a big honkin' natural gold nugget 8 inches deep in limestone terrain (!). No need to actually bury the target before "finding" it, all the target has to do is to show up in the hand with the camera running. The purpose of the electronic pinpointer is to lend an air of authenticity, and a beep to illustrate that at least it's metal (no need for it to actually be gold). Where was the swingin' metal detector meanwhile, almost anything woulda found that nugget in that location 8 inches deep had it been there (which it wasn't, thats the problem)? And tell me with straight face that there's an LRL customer base for electronic pinpointers who don't use regular metal detectors.......
The purpose of this kind of advertising is to "qualify the customer". In the LRL business, they don't want unhappy customers. So the advertising is aimed dead center at people who have a subconscious desire to be bamboozled. Once they've been bamboozled, they got what they wanted and rather than being unhappy, they've got all kinds of alibis how it probably sorta works somehow. ......And, the occasional customer who was just plain not thinking when they bought it, that customer may be parsed arf at gettin' took, but if they complain they are admitting how gullible they were, and that's a strong deterrent to complaining.
