Enhanced Sensors

Enhanced Sensors is a perk in Fallout: New Vegas given to the Courier while they have ED-E or its copy as a companion.

Effects
This perk greatly extends the player character's detection radius, the equivalent of having a full 10 in Perception (in essence, ED-E's detection is substituted for the player character's). It also allows the player character to target cloaked enemies in V.A.T.S. mode. When paired with the Spotter perk given by Craig Boone, the player character can effectively snipe targets from much greater distances.
