Lee Valley Starrett Digital Protractor

In addition to the standard protractor functions for measuring angles and calculating bisected, complementary and miter angles, this digital protractor also calculates rake and bevel angles at the touch of a button, greatly simplifying miter saw settings in crown molding work.

The two overlapping arms have a digital LCD readout at the pivot that instantly displays inside and outside angles over a 360° range in 0.1° increments. The readout zeroes at any position for differential measuring, and the arms lock at any angle for direct transfer to a miter saw. A hold button keeps the measurement displayed, so you don’t have to commit it to memory.

Rigid, durable and corrosion resistant, the 1/4″ thick anodized aluminum arms provide ample surface contact for reliable registration against a wall or miter cut, and integral bubble vials let you check for plumb and level.

Runs on a single button-cell battery (two included). An auto-off feature shuts the display off after a period of inactivity to preserve battery life.

Well made in USA.
