The General Tools 822 is a 5-inch stainless steel ruler with a digital angle readout built into the hinge. It reads interior and exterior angles across a full 360°, with ±0.3° accuracy and 0.1° resolution on a large LCD. A lock holds the angle and a reverse-angle button flips the reading for tight spots. It suits woodworkers, trim carpenters and DIYers who want one pocketable tool for both angle and length checks. Against digital protractors, the ruler blade makes it more useful for marking and transferring angles, but its short 5-inch reach limits it on long runs where a larger angle finder or bevel gauge does better.

Owners of the 822 generally find it accurate and handy for trim and shop work, and like having a ruler and angle readout together. Complaints center on the short blade and on the hinge moving when it is not locked.
The General Tools 822 is a digital angle finder with a built-in 5-inch stainless steel ruler. It measures angles and lengths with one tool. A full 360° hinge lets it measure both interior and exterior angles.
A large LCD display shows the angle reading. The hinge can be locked to hold an angle for reading, and a reverse angle function is included for specific applications. A center check notch helps with placing the ruler.
To use it, press the power button and adjust the hinge to the desired angle. Lock the angle, then read it on the display. The built-in ruler handles length measurements. It is used in woodworking, construction and DIY work.
