Fallout - Vault 53
Pip-Boy Model No. 3000
The 3000 model has a built-in radio and Geiger Counter.
The Pip-Boy 3000 features a biometric lock that can only be opened by either the user or a skilled technician.
The Pip-Boy 3000 also features a light that illuminates the area around the user, allowing them to see better in the dark.
It displays information in bright green on its black 5″ × 3″ screen.
It can record sound and video footage for later playback. It uses a simple but elegant form of sonar and satellite tracking (where available, which is far from everywhere in the post-apocalyptic world) to map out areas where its user travels.
Though input is slow, a user can also hand-enter and edit text messages on their Pip-Boy’s using such devices as a crude form of short range comunication
