Replacing the original 4-in-1 AnglePro Digital Meter, the new AnglePro II uses a commonly found CR2032 lithium battery and has an auto power-off feature. The incidence attachment allows precise digital measurement of airplane wing, tail, and thrust angles, and allows for easy calculation and adjustment of control throws. The AnglePro II attaches to most control surfaces and resets to zero at any angle, so there’s no need to level the airplane. It also works as a precision level.
