Dead Money Collar

The Dead Money collar is a piece of headwear that is worn around the neck in the Fallout: New Vegas add-on Dead Money.

Background
Obtained by Elijah at Little Yangtze during his investigation of the Big MT, these collars are more advanced then the more commonly seen slave collar due to Elijah's adjustments. He altered and improved them during his stay in the Big MT, so now they can be detonated remotely through a special radio frequency, as well as being programmed to detonate should other slave collars go inactive (due to the wearers death). Because of these added features, Elijah finds the collars a perfect tool to get unsuspecting wanderers of the wastes to aid him in his efforts to break into the Sierra Madre vault.

Characteristics
Providing a Damage Threshold of 3, this special collar was developed in the Big MT. It can be remotely detonated by Elijah should the wearer try to disobey his order, or attempt to escape the Sierra Madre. Being far from perfect, the collar can be accidentally set off by certain radio frequencies. This makes it a dangerous thing to wear around any of the casino's decayed, yet still active, radios or speakers. Coming within 8 yards of a radio or 12 yards of a speaker will start a 10-second countdown; if the player does not leave the radius or disable the radio or speaker within that time the collar explodes, the player will die instantly. If the player has Christine Royce as a companion, the countdown is extended to 15 seconds.

An additional feature of the collar, installed or activated by Elijah when it became clear that groups tended to fail because of fighting among themselves, is a dead man's switch function. This will detonate all collars within a specified group should one of those members die or be killed. The signal can, however, be blocked by Saturnite alloys.

Locations
One is automatically equipped at the beginning of Dead Money and cannot be removed until the completion of Heist of the Centuries.
