Wrist computron

A wrist computron is a portable device carried by Troy and Dillon during their first adventures on the newly-discovered Earth.

The complete features of the wrist computron are not defined, but the device has four basic functions: communication, translation, data storage/retrieval and scanning capabilities.

One feature, personal invisibility, is used by Willy to torment a bully, Tucker (Galactica Discovers Earth). Later, the invisibility feature is used by Troy and Dillon to avoid questioning by the Federal Bureau of Investigation after thwarting a hijacking attempt on an commercial air plane (The Night the Cylons Landed, Part I).

Those using the invisibility field emitted by the device cannot see others who are also invisible using the same device; Troy and Dillon hold hands while quickly exiting the plane so as to remain in close proximity during their escape (The Night the Cylons Landed, Part I)

It is also used by Dillon to translate Earth terms he does not understand, in addition to providing information on the many aspects of Earth, including its locations and organizations (The Night the Cylons Landed, Part I).
