The player is equipped with the Pip-Boy 3000A; it is indicated that there are other models in the 3000 line, with A being one of the oldest. The Pip-Boy 3000A is worn on the character's left forearm. This multifunction device has been programmed by RobCo to display the wearer's stats, area maps, inventory, and item properties. It also includes a Geiger counter and a radio, and its screen doubles as a flashlight. A user can set their color preference for the display. The four colors available are amber, blue, green, and white. The display color must be changed through the pause menu rather than the Pip-Boy itself.
