Nearly every build of Detect I've used has Reflexive to make it into a sense, and most of those have an enhancement to get rid of the -4 for Reflexive. Some don't because it makes more sense with some abilities that active use makes it better (or not worse, however you look at it).

I really do wonder what the differences between Scanning Sense and Detect are. I've almost never used Scanning because it never seems to do what I want it to.

One great thing I like about Detect is how much it can do, from a build perspective. It's one of the few traits that canonically has the limitation 'You dont have this trait'.
