Over the years many UFO sightings have reported magnetic and electromagnetic disturbances. The UFO Detector is designed to sense these disturbances and will signal their presence by flashing an LED and beeping.
I don’t dare to say that there’s people out there who would actually buy these UFO detectors for the sake of… well, detecting UFOs, but you never know. Anyway, from a nerdologist point of view I think they could be classified as gadgets, as they are small, expensive and, unless you live near Roswell, you don’t really need them (but still want to try them, eh…).
By the way, don’t miss the explanation of how they work. Since asking a local ET to fly nearby to try the device seems a little bit unpractical (lots of bureaucracy, mainly), at least they give several alternative ways to see that it works (whatever that means).
All in all, these UFO detectors, though expensive, are probably the best gift for those who want to believe (sing the soundtrack with me: nanananán-nanán-nan-nin-nin-nin-nin).
