How do I get a 9-meter waist board level in the easiest way?

Hose water level?

It should work, but as far as I know, the slangvattenpass doesn't have a motor or battery, so that would be a no-go for me. I would use a laser. It might be the best tool one can own. Set up the tripod, turn on the laser, and voilà, a 100% straight line!

Well, not that I've noticed, you can do that and check with my newly purchased hultafors mst180 before resorting to another method.

My laser is not visible in daylight

Out one evening and attach it to the wall. The next day, it's done, you fasten it. Or mark a couple of points on the wall, the next day it's up with it.
