Enhanced Sensors

 is a perk in Fallout: New Vegas given to you while you have ED-E as a companion.

With this perk you can detect enemies at a very far range, and enemies that are cloaked can also be targeted in V.A.T.S. mode. It works extremely well with the Spotter perk given by Craig Boone.

This perk has no effect in most compact indoor areas (e.g. buildings/caves/vaults). Together with ED-E's poor damage output, ED-E is virtually nothing more than a mule in indoor areas.
