Slave collar

The total pacification collar (commonly referred to as a slave collar) is a pre-War prisoner control device developed at Big MT Research and Development Center, and adapted by slavers after the War for the purpose of capturing and forcing slaves into submission. 

Background
Slave collars have a simple, but deadly design. Encased in five pounds of durable steel is a small explosive charge, a microphone/speaker and a radio wave receiver and transmitter. When remotely triggered, the receiver signals the detonation of the charge, obliterating everything above the neck of the wearer without damaging the surrounding area. The collar's transmitter constantly broadcasts its position and environmental input to the controller, meaning wearers can be constantly monitored and eavesdropped upon. In addition, the collars are designed to detonate if they are removed without a disarming signal; it takes quite the expert in explosive circuits to get one off without such a signal. The collars can even be adjusted to detonate if the outgoing signal of another nearby collar goes silent. However, their simple design can be their downfall: the collars do not have selective radio wave jammers, meaning that rogue background electromagnetic waves can interfere with the receiver and set off the collar.

After the war, they have found widespread use among the survivors, usually slavers. However, some also use it for simply ensuring cooperation, such as the Brotherhood of Steel and Father Elijah, without the risk of hostilities.

Dead Money collar


A slave collar from Big MT that Elijah tinkered with to make his captives obey orders to crack open the Sierra Madre Casino.

Deactivated bomb collar


A slave collar that Elijah tinkered with in order to understand its internal workings. This allowed him to alter other bomb collars, namely the Dead Money collar above.

Shock collar

Behind the scenes

 * Exploding collars are frequently used as plot devices in fiction entertainment. The earliest known use of an exploding collar was in the Starchild Trilogy, a trio of novels published between 1964 and 1969.
