Bob, I've always wondered how a laser level could be more accurate than a water level. I'm not disputing the claim but I've never understood how its possible. I'll explain my quandry..  a laser level is only as level as the little bubble will make it. I've found some that aren't even close to level when they 'say' they are.  A water level [ all things concidered like bubbles and wind] will sit perfectly level  once properly set up, we know that water will seek its own level. I'm not convinced that a laser level is better. Am I missing something??

Curious is all  :)
