Stealth Boy (Fallout 4)

Stealth Boy is a consumable item featured in Fallout 4.

Characteristics
Unlike the Capital and Mojave Wasteland variants of the Stealth Boy, this version isn't worn on the wrist. Instead, it seems to be activated by hand and is also held on the waist, like a satchel, but not able to hold anything.

Locations

 * It is found in Park Street Station once you head downstairs, go straight across all the tracks and there will be a locked room on the left as you reach the far wall requiring novice lockpicking. Once inside there is a safe towards the back of the short tunnel requiring expert lockpicking and the device is located in there.
 * One stealth boy can be found in the ArcJet Systems building.
 * One Stealth Boy can be found in Back Street Apparel. After entering the building, enter the first door on the left.  After picking the locked door in the hallway, it will be on the shelving to the right.
 * A Stealth Boy can be found in Federal ration stockpile. After entering, at the first intersection of hallways (with the construction light, just past the two can traps), turn right. Go down the stairs to the metal walkway, then jump across the gap.  The Stealth Boy is by the two skeletons in the room on the other side of the gap.
 * One can be found in the National Guard training yard upstairs in the smokey room.
 * Two can be found at the castle behind the large metal door.
 * One can be found on the desk in the medical lab in secret Vault 81.
