Digital technology has transformed the world measurement, allowing woodworkers and others to achieve levels of precision never before imagined, in places never before thought possible. Measuring angles is one of those areas transformed by digital technology. Where before we were limited to accurate 90-degree angles, with everything else being plus or minus a degree or two, this digital angle finder measures and can set angles down to an accuracy of 1/20th of a degree. Such precision is especially useful for setting table saws blade and miter gauge angles. Features: 8” long stainless-steel scale – longer than other digital angle finders Scales (two) calibrated in both inches and millimeters, laser engraved for long life Large digital readout with 10mm tall numbers – reading accuracy to 0.05 (1/20) of a degree Zero function allows you to re-zero the tool for every use Hold button to retain measured angle for viewing Lock knob to hold set angle for setting tools to match that angle Ideal gauge for setting angles on table saws and other power tools
