The Stealth Boy is a personal device that generates a modulating refraction field. Using it effectively renders the wearer invisible for a short period of time.VDSG Catalogue No.9687

A Stealth Boy is a consumable item in Fallout 4.


The Stealth Boy is a portable device that, when activated, renders the user invisible for 30 seconds.

Unlike variants of the Stealth Boy found in New California as well as the Capital and Mojave Wastelands, this version isn't worn on the wrist. Instead, it is activated by hand and is held on the waist, like a satchel.


They can be found scattered all over the Commonwealth or they can be sold by merchants.


  • While still capable of aiming with scopes after activating a Stealth Boy, glow sights and reflex sights will be cloaked as well (and thus unusable) for the duration of the effect. Therefore, aiming at distant targets will become more difficult.
  • With Deacon's companion perk, Cloak & Dagger, the duration of Stealth Boy effects last 40% longer.
  • If one is given to Deacon, Cait or X6-88, they will use it in combat.
