Clickers don't make sense. Or rather, their echolocation doesn't. That's not how echo location works. Even if you were silent, if you're in direct line of sight of one, the clicking sound they make would still bounce off of you and make you 'visible' to them. Then again, as pointed out above about how spores actually work, more things don't make sense in the game.
That being said, as an enemy they're pretty good. I never liked instant death mechanics, but otherwise they provide nicely tense moments.
