Abstract: A device capable of gauging angles in the full range from 0.degree. to 360.degree.. The angle gauge has a pair of pivotally connected gauging arms. Each gauging arm is formed by a generally radially outwardly extending leg connected at one end to the pivot axis and a radially offset straight edge leg extending generally laterally from the opposite end of the radial leg. A full 360.degree. angle scale is fixed relative to one of the gauging arms coaxially with the pivot axis and extends radially outwardly a distance less than the offset of the straight edge. A pointer is fixed relative to the other gauging arm as a reading indicator operably associated with the scale. The arms may be clamped in selected angular positions and also may be used to lay out several angles about a common vertex.One of the gauging arms has a pitch scale formed along it and the other arm has an indicator mark formed on it.
