Liking the new HACKER Perk

In MW2 i don't have a setup without SitRep now as it has become vital in S&D and in Black Op's i think i may like it even more:

Hacker | Hacker Pro

Ability: Allows you to see enemy explosives, equipment and Tactical Insertions. This highlights them with a red color like SitRep from Modern Warfare 2.

Pro Ability: This is one of the most interesting additions to the whole Black Ops perks list. Hacker Pro actually allows you to booby trap enemy Care Packages and also turn enemy killstreaks and equipment friendly.
