An Omnispex is an Imperial scanning device that carries a Raptor-class Machine Spirit (artificial intelligence) that can read heat emissions, data signatures, and other biological electromagnetic waveform emissions even at extreme range. Should it be kept focussed for an extended period of time, an Omnispex will determine the weak points of those it scrutinises and pass them on to its master.
