The Pip-Boy 3000 Mark IV is a pre-War Personal Information Processor (PIP) in Fallout 4 manufactured by RobCo Industries and acts as a database for the player character's personal information and inventory. It is an updated version of the Pip-Boy 3000.

Background
The Pip-Boy 3000 Mark IV was distributed to all 5 vaults Vault-Tec vaults in the vicinity of Boston: Vault 75, Vault 81, Vault 95, Vault 114 and Vault 111.

Functions
The new Pip-Boy features a number of similarities and differences between previous models. It bears closest resemblance to the Pip-Boy 3000. According to the start-up screen, its features include:
 * Pip-OS v7.1.0.8
 * 64k RAM
 * More than 38,911 bytes of internal storage

Statistics Menu
The statistics menu, or 'Stats' shows the Sole Survivor's health and status, the levels of their SPECIAL attributes, and the various perks they have acquired through level up. This screen also shows current health, level, experience, and AP.

Inventory Menu
The Inventory menu is where the sole survivor can check the weapons and armor they are carrying and currently have equipped. The menu comes with:
 * an aid tab for items such as medicine, drugs, food and water
 * a miscellaneous tab for carried items that don't fit into the other categories, such as keys, ID's, notes and bobby pins
 * the junk tab for all items and resources you have collected that can be used for crafting
 * a mod tab, where you can see the item modifications to be used in weapons and armor at workbenches
 * the ammo tab, which shows all currently carried ammunition for the various weapons you have.

Additionally it should be noted that this pip boy, while being a newer variant of the pip-boy 3000, does not have a keychain and is susceptible to key clutter in the miscellaneous tab. The weapons tab lists carry weight, current caps, and shows an icon for the equipped weapon type and the ammo it holds. The armor tab is set up similarly, with the current armor energy weapons, radiation, and damage resistance levels being the exception. All other tabs within the inventory menu will show the current carry weight and cap level, with aid also showing the health bar.

Data Menu
The data menu is where the sole survivor goes to view any current or completed quests and miscellaneous objectives, examine the well-being of their settlers and settlements via the 'workshops' tab, or can overview their general statistics in the game so far. The statistics tab has as follows:
 * 'General', showing locations seen or cleared, days passed in-game, hours slept or spent waiting, caps found overall, etc.
 * 'Quest', which has quests completed, miscellaneous objectives completed, main quests and side quests completed
 * 'combat', which lists various NPC's the player has killed
 * 'crafting', for mods and plants harvested, chems crafted, food cooked, etc.
 * and 'crime', which lists all of the crimes that the player has committed, but also shows locks picked and computers hacked.

Map Menu
The map menu opens centered on the player's current location. It can switch between world and local maps (PC default key [R]).

Radio Menu
No longer in the data menu, radio stations now have their own. Diamond City Radio and the Classical Radio will always be shown by default, with new radio stations appearing as they are unlocked. If you are outside the functional area of a radio station, it will be grayed out and will not be selectable.

Pip-Boy light
The display of the 3000 Mark IV can set set to an over-bright mode to provide illumination in dark areas. The color of this light matches the user's selected display color preference.

To activate the Pip-Boy light, hold down the Pip-Boy access button. The default Pip-Boy access buttons are the  key on PC, the circle button on PS4, and B on Xbox One. The Pip-Boy light can be deactivated the same way.

Adapter plug
A unique feature of the 3000 Mark IV is an adapter plug attached to the underside of the device. This plug is used to open and close the main doors of vaults in the Commonwealth, effectively making the Pip-Boy a vault key.
