Explosive Collar

The explosive collar is a piece of headwear in Fallout: New Vegas.

Characteristics
It is commonly used on slaves, and explodes via remote trigger (usually held by a slaver) or attempting to interfere with the collar's wiring.

Locations
The Brotherhood of Steel will force the Courier to equip one when they first meet as a way to make sure the Courier does not reveal their location to the enemy (unless the Courier is accompanied by Veronica Santangelo). The captives in Dead Money (including the Courier) and Mrs. Weathers and her two children, Kenny Weathers, and Sammy Weathers from the quest Left My Heart are also equipped with them.

Bugs

 * When the collar is equipped during Still In The Dark, the Jury Rigging perk can be used with the Explosive Collar to fully repair any amount of headgear without removing the collar.
