Precision Bevel Protractor

Very accurate. I find this protractor very helpful in measuring bends, radius in tubes and brake lines, and odd angle measurements a standard square cannot accurately obtain. The degree lines are very sharp/small, and need to be in order to obtain accurate measurement from a tool of this size, so, a magnification glass of some sort it needed. However, the magnifying glass that comes with the tool is cloudy. I am having better luck in reading the degree angles with the accompanying magnifying glass removed and using a quality, lit magnifying glass.
