how to use a water level?

[hrsdennis]

Matt, I followed your links and did some research on the water level. Looks like it would be easy and accurate. The only variable I see is evaporation. So what if it takes a year or more to level the red clay.

They are not cheap but the only way I have found to use a laser outdoors in the daylight. No matter how expensive the unit. They have really neat beep sounds to tell you when you are level. I silence that of course.
