A lifeform scanner, also known as a life-form sensor or lifeform detection module, was a device that allowed the holder to detect living (sentient and non-sentient) beings from a distance. A large majority of bounty hunters and mercenaries used this technology to lock on to enemies and potential bounties. Lifeform scanners could also detect beings hidden by cloaking devices, stealth fields, and sound dampeners. A large manufacturer of lifeform scanners was Idellian Arrays.
They were equipped onboard Guardian-class patrol ships.
