Lockcracker
Description: Lockcracker was clearly adapted from a 1950s one-handed Geiger Counter; the cover and dials have been painted over, the buttons have all been disabled, except for one painted red, and the hand-held sensor unit has had three wires added. One wire ends in an alligator clip; another in a thin, flat piece of metal with rounded edges, and the last in a what appears to be a very tiny microphone. If Lockcracker has batteries (the casing is quite thoroughly soldered), they haven’t been replaced in fifty years.
