Anyone using the bushnell laser range finder with "ARC"?

I've used the regular range finders for some time now, mostly for work.  They work fine and hold up to light amounts of abuse.  I'm considering buying a new range finder with ARC, but don't really know what the advantages are.

For example, if I walked outside and lasered to the roof of a building would it give me a different measurement than a rangefinder without ARC?  What would be the differences?

I have the 1000 with ARC.  I like it alot.  You can set the bullet drop to your ballistics on your rifle.  And if your a bow hunter, It will show the differences at angle.

Does it tell you the actual angle your aiming at?
