The police literally said as much, in the Wikipedia article for a similar device, the Quadro Tracker (https://en.wikipedia.org/wiki/Quadro_Tracker https://en.wikipedia.org/wiki/Quadro_Tracker), which hilariously "could detect hidden drugs, explosives, weapons and lost golf balls": > The Jefferson County, Texas narcotics task force spent $3,250 on a Quadro Tracker. The task force's commander later said: "We played with it in the office and got mixed results. Sometimes we'd find something, sometimes not. Our rate of success was about half. I think it was either blind luck or a ouija board effect. It's not near as consistent as (drug-sniffing) dogs, but there are no vet bills."[13]
