Flux sensor

The flux sensor is a quest item in Fallout 4 that can be returned to Scribe Haylen for caps.

Characteristics
The flux sensor is a piece of technical hardware sharing a model with the sensor module on the front, though the back of the device is unique to this item.

Locations
This item can spawn at various locations once the quest Quartermastery is accepted from Scribe Haylen. A map location and quest marker will be added for the area it has spawned in.

Behind the scenes
On the back, the device is identified as "FLUX SENSOR CM-88B 180924609." This is a rather obscure reference to the movie Alien, specifically the central vessel the movie takes place on, the USCSS Nostromo - the CM-88B refers to the ship's model; the 180924609 refers to the ship's registration number.
