There are laser levels and laser levels - the best are the most expensive and should be calibrated before using on exacting requirements. I've seen two laser levels side by side with a wide variation. Not Good!

Good to know guy's. The main reason I asked was my father and I used a laser level [ his new gaget of the week at the time] to check the level of the wings on our plane. We got it all set up and then just for a double check used a water level. The water level showed a 3/8" 'out of level' or 3/16" from tip to tip. Needless to say.. I wasn't impressed. I think in the future I'm just going to borrow the Transit from work.

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  :)

Jarrett, Some of the Laser companies have rotating levels that self level using a spherical track and rotating. I have one and can attest that the thing does a great job. Did my barn foundation with it. My friend is a surveyor and shot the foundation for practice and said it was within 1/8"! (24' x 36') He was supprised. The water level will work of course with patience.
