Can Blindsight "see" around corners?

[Eltab]

Bats have blindsight, based on sonar. They can't see around corners but they can "see" in the dark.
Radar is another form of blindsight, with somewhat different effects. Try using radar to "see" something with no metal...

In most cases, straight-line line-of-sight should apply, but any given monster might be an exception, if you have / can find a reason for it to be one.

Thanks for the suggestions. I think I'll stick with it not seeing around corners. Seems to work best that way in most situations. It does mean it's not as big of a boost as it could be (for a dragon, for instance), but removing the Perception penalty in dim light is pretty good anyway.
