A multi-purpose carpentry measuring device is described. The tool combines the functions of a framing square, level and plum bob in one function and with just one measurement. Further, the tool can also be used as a bevel gauge and a level bench marker. A foot and leg member, joined by a pivot, contain bubble tubes for all necessary horizontal and vertical level measurements. Extendible rules on both members further increase the usefulness of the device. The tool has a built-in magnetic disc and bar code reader for continuously displaying angular read out on an integral calculator. Laser pin lights at either end of the tool allow for laser precision in all level bench marker observations as may be facilitated by a positioning pin disposed in said device.
