Digital levels

Don't forget that however accurate the level is it is only as good as the
surface you rest it on. A good quality bubble level is accurate to 1/10th
degree, and a large protractor with weighted pointer is almost as good. (like
the one in the plans) The analog readings are less confusing to some of us.
