The distress pulser is a junk item in Fallout 4.
Characteristics
The distress pulser is a device used by the Brotherhood of Steel to mark specific locations, or in the event of an emergency where a soldier or squad may be downed and in need of assistance. When active, it emits a series of blips to any device capable of picking up radio frequencies, which become clearer as the receiver travels closer to the source.
Crafting
The distress pulser can be broken down into its individual components for use in crafting:

Notes
- Taking the distress pulsers during the quest The Lost Patrol causes the signal to disappear.
- Dropping a distress pulser will cause the signal to reappear.
- During Liberty Reprimed, Haylen will give the Sole Survivor a distress pulser to mark the location of the stockpile of Mark 28 nukes in the Sentinel site.
Bugs
There is a bug where if a distress pulser is dropped on the ground in a settlement and then scrapped using the settlement building screen it will permanently emit a distress signal. It will also continuously emit a signal if it is used to build modifications, so the only way to remove the signal permanently is to sell it after finishing the quest. [verified]
