Suliban Hand Scanner
A scanner is a generic term referring to a hand-held sensory device. Scanners were common during the mid-22nd century and used by a variety of space-faring cultures and institutions such as Starfleet, the Earth Sciences Institute, Ferengi privateers, the Suliban Cabal, and the Vulcan High Command.
Scanners were the presumed precursors to the tricorder of the 23rd and 24th centuries.
Also similar in design and shape to the Vulcan scanner, the hand held sensing device utilized by members of the Suliban Cabal featured a rounded interface area, with an extended handle. Mottled-brown in color, this scanner also featured a purple readout.
Presumably along with a handful of other functions, the Suliban scanner was capable of locating an individual's distinct bio-signs and could detect temporal signatures. (ENT: "Shockwave, Part II")
