I see, that makes sense. If it wasn't like the analogy of blinding him with a flashlight in a pitch black room. Now he'd know where to go.

I was thinking more like the displaced water creating sort of a horizontal mushroom cloud deflecting/distorting the active wave. But I don't know if that works at all in RL.
