  • Gauge for determining angle of sloped ground and method of using same
    Patent number: 7891107
    Abstract: A gauge for determining the angle of sloped ground includes a panel, having a transparent window located in it, which can be held by a user so that the sloped ground can be viewed through the window. The panel has a spatial reference associated with it which allows the panel to be oriented properly with respect to the horizontal or vertical. Inscribed on the window are a positioning indicia and a plurality of lines which radiate outwardly from the positioning indicia at specific angles with respect to the horizontal. In use the panel is held such that the positioning indicia is located on the slope. The user can then determine which one of the lines overlies the slope. The angle associated with that line is the angle of the slope.
