1. A level comprising:
a housing comprising a longitudinal axis;
a planar base surface extending parallel to the longitudinal axis;
a first orientation sensor configured to measure an orientation of the housing with respect to the force of gravity, the first orientation sensor defining a first angular position relative to the planar base surface;
a second orientation sensor configured to measure the orientation of the housing with respect to the force of gravity, the second orientation sensor defining a second angular position relative to the planar base surface, wherein the second angular position is oriented at a 90 degree angle with respect to the first angular position;
a controller that calculates an orientation of the housing based on the orientation measured by the first orientation sensor and the orientation measured by the second orientation sensor;
a display that emits an image that corresponds to the calculated orientation of the housing; and
wherein the controller calculates an orientation difference between the calculated orientation and a target orientation, and wherein the image comprises an exaggerated representation of the orientation difference.
