With a powerful, ceramic magnet base, this angle finder can be used either as a 'quick check' tool or can be used to convert a rule or square into a precision angle finder. Possessing a V-groove, an accuracy ±0.5% and dial reading of 90°, it is recommended that the angle finder is attached to a steel rule or square by means of the magnet or screws for optimum,um levels of accuracy.
