Signal tracking device

A scanner is a kind of UNSC detection equipment seen being used in part 2 of the Arms Race video trilogy. The scanner appears to be used for displaying the location of a tracking signal. It is possible that it is used for other purposes, although none are shown.

The scanner appears to have a flat panel display and emits a beeping that gets faster the closer it is to the target.
