It's a strange box thingamajig wotsit made out of metal (I think) with a sort of antennae coming out one side, and you can wave your hand or an object above it and it emits these strange high wailing sine waves, and ghostly whines and whistles etc. depending on object position.

Don't think i've ever known what they're called, anyone recall?
