Certified Tech

Certified Tech is a perk in the Fallout: New Vegas add-on Lonesome Road.

Effects
Your knowledge of robotic components allows you to break them more easily and salvage their mechanical corpses. You have a +25% chance to score critical hits against robots, and you'll also find more useful components on robots you destroy. To be specific, the perk adds a 85% chance that a robot will have one fission battery, two scrap metals, two sensor modules and three scrap electronics on its body upon death. This is added to the items it would normally have, not replaced.

Note
It actually only add 0.25%, not 25% as description.
