Destroyed Collar

The destroyed collar is a slave collar that has detonated, and can be used as a necklace of sorts.

Characteristics
The collar has zero DT, and no in-game effect except for being visible as a bulky metallic collar on your character if worn. It has an annoying weight-value ratio.

Locations
It is obtained when you start the Brotherhood of Steel story line but is removed after the first quest you do for them. It can also be found on a corpse labeled "Man" in a ruined building at Freeside's East Gate near Jacob Hoff and across from Mick & Ralph's, which is part of the I Could Make You Care quest line, if choosing the rangefinder.

Appearances
The destroyed collar appears in Fallout: New Vegas.
