Destroyed collar

The destroyed collar is a piece of headgear in Fallout: New Vegas.

Background
One of many modified by Father Elijah, this was used collar to force an unfortunate wastelander to purchase a rangefinder from Sarah Weintraub. Once he had acquired what he was tasked to purchase, the man tried to remove the collar himself. He inquired about someplace with concrete walls that was free to stay, Sarah referred him to the ruined building outside Mick & Ralph's in Freeside. This where, judging by the decapitated body and the wrench near the body, he attempted to disarm it and detonated it in the process. Oddy, the collar, despite detonating, is still intact.

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.

Locations
It is found on a corpse labeled "Man" in the westernmost corner of 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.
