The Protector is a precision, highly accurate and simple to use device for checking, setting or changing propeller pitch. The resolution and repeatability is 0.05 degree and the accuracy is +/- 0.1 degree. It is powered with a standard 9 volt battery with approximately one year use life.
The Angle Cube can be used for other angle measuring applications such as checking and adjusting wing incidence, rotorcraft blade angles and tail-dragger ground angles. Aside from aircraft or airboat use, the gage can be used for measuring or setting table saw blade angles, machining or drilling angles or any other application requiring precision angle measurement. Magnets on three sides can be used to hold the unit to appropriate surfaces.
When the Angle Cube is magnetically attached to the protractor clip, the unit becomes a simple and accurate tool to measure blade angles.

5 stars on Competition Aircraft after market service! I had an issue and they took care of it immediately. Well worth buying this product for them on that basis alone. Oh, and the protractor works great as well.
Very accurate. I used my laser level on a tripod to set measurements for vials and mounting bracket.
Best and most accurate way to set prop pitch
