Abstract
A level system for accurately and efficiently providing a levelness measurement. The level system includes a container positionable within a frame structure for retaining a volume of liquid, a upper compartment within an upper portion of the container for retaining a buoyant member, a first paddle and a second paddle pivotally attached within the container about the buoyant member, and an indicator member attached to the paddles for indicating a levelness or plumbness of a structure. As the buoyant member moves within the upper compartment, the paddles move the indicator member accordingly.
