The Rule is stainless steel (in mm and inches (1/16", 1/32" and 1/64"), and the Digital Readout measures a full 360°, with a resolution of 0.05° and an accuracy of 0.2°. Battery included which has a continuous run time of 1 year. The locking knob is very solid. Gives great accuracy at a modest cost. A good value for sure.
