I've been looking at laser levels. I've found a "rotating" laser level which (as far as I can understand) sits on top of a tripod or any solid support in the middle of a room, and which you can then rotate to project a laser beam to all points around a room, thus creating a level line around the whole room. Useful, eh?
Forgive my ingorance of these things, but isn't that what all laser levels do? How do the non-rotating variety work? Come to that, how would I use a laser level if I wanted, say, to check the level on a worktop or shelves as I was setting them up? Normally, I'd put a spirit level on the three dimensions of the item, and adjust until everything was level/plumb. How would I do this with a laser level?
