Slave collar

The Slave Collar is a Collar used by the Slavers from Paradise Falls. It has 1 weight and 0 value and cannot be removed from the inventory due to being a quest item. Due to glitches you may have extra collars that become permanent weight. It is said that the collars send out a frequency to Paradise Falls and keep track on where every collar is located. The Collar is equipped with explosives and is set off as soon as a Slave tries to escape.

Grouse keeps track of all Collars.

The origins of the Slave Collar are unknown. It is possible that they are fabricated by the slavers since their design seems relatively simple, though it's more likely that they are pre-war in origin. At times the player character will be approached by an Escaped Slave who will beg him or her to remove the collar. Explosives skill is required to successfuly remove the collar. Otherwise it will explode.

The Player Character receives a Slave Collar and a Mesmetron for use in the Quest Strictly Business.

Glitches

 * An unknown glitch may occur during the Strictly Business quest in which Grouse will present the player more than one collar at a time.
 * By talking to any of the VIP slaves after enslaving them, and telling them to "deal with [being a slave]", Grouse will reward the player again and give the player another collar. (Fixed by 1.1 Patch)
 * If the player receives more than one slave collar, enslaves multiple people, and then returns to Paradise Falls, Grouse will say that you have lost the collar and makes you pay for a new one. Also, if the player receives more than one slave collar and enslaves more than one person, Grouse may still pay you for one slave, and you will receive one collar.
 * If you have more than one slave collar, there is a way to get rid of them. Simply find someone and mezz him/her to put the collar on. Then tell him/her to go to Paradise falls, when they start running, kill him/her and return to Grouse. He will be annoyed and will say that you will have to pay for a new collar, refuse to pay him and he will tell you to come back if you want another collar. However, when you exit the dialogue, there will not be an option to buy another slave collar if you already have one. Do this to get rid of the extra collars you have.

Two versions
The slave collar is actually two separate items: the quest item given to the player by Grouse, and a hidden apparel item that is generated on NPCs that the player enslaves.

The Player can wear the latter by typing the following into the game console:
 * to add a collar to your inventory (it won't show up on the pipboy)
 * to equip it.

To remove it, type.

Trivia
The only way to remove a slave collar from inventory is to enslave someone. That means if you start Strictly Business then kill the slavers, you have to enslave someone to get rid of the collar. Otherwise, it remains a quest item even if Grouse is dead.

The idea of an exploding Slave Collar is featured in quite a few movies and novels. Such as:
 * The Running Man,
 * Wedlock, also widely known as Deadlock,
 * Saw III,
 * Battle Royale and Battle Royale 2: Requiem.
