The Devore scanner was a scanner used by the Devore species.
It had two prongs on the front, a grill along the rounded bottom edge and a single screen the holder could monitor. It was capable of telling whether a person had telepathic abilities or not, so boarding parties were often equipped with them. Though this required the scanning of each crewman individually.

In 3190, Haz Mazaro told Cleveland Booker that he was offering a special on Devore scanners and modified scan deflectors. Doctor Ruon Tarka complained that the scanners could not "pick out a Betazoid standing all alone in a Nieser cage." Nevertheless, he later was able to modify one to create a force field to trap a Changeling. (DIS: "All In")
The prop representing the Devore scanner was later used as Mobar's scanner and religious item in "Live Fast and Prosper".
