Pulse mine (Fallout 3)

The pulse mine is a weapon in Fallout 3.

Characteristics
The pulse mine consists of a proximity fuse and miniaturized EMP device enclosed in a gray metal casing screwed to the base. Armed status is indicated by four red diodes situated on top of the cover. It will begin beeping when a target comes within a short distance to it until it is disarmed or it detonates. The time until detonation depends on the Explosives skill of the person setting it off. Both soft and armored/robot targets will activate the fuse.

On detonation, the pulse mine creates an electromagnetic field affecting any functioning robots and turrets. The blast deals little damage to non-robot targets in close proximity to the detonating device. The pulse mine will become live and likely to cause instant death after it's dropped into non-player character's pants (inventory) via theft.
