【Laser Function】 - This digital angle finder measures angles, checks relative angles with the zero calibration function, and can also be used as a digital level. The magnetic angle finder and two side lasers are great for measuring, cutting, and leveling during wood and furniture construction renovations. It has wide applications in the woodworking, HVAC, construction, machinery, automotive, and DIY industries. Magnetic Base on Four Sides: The digital inclinometer with a powerful magnet on four sides can be attached to any ferrous metal surface such as pipes, steel structures, metal constructions, and other ferromagnetic surfaces. Our angle finder is an excellent aid and a great choice for measuring and setting the angle. 4 * 90° measurement can be used at various angles and reset to zero for comparison at any angle. 【Absolute and Relative Modes】 - The digital angle measuring tool features two measurement methods – absolute and relative angle measurement (the absolute zero position of the digital angle detector has been calibrated from the factory); Auto power off – after 3 minutes without input or movement; Auto reversible display – when the meter is upside down; Hold button – freezes the current measurement. Zero calibration function. 【USB-C】 - This woodworking tool is rechargeable and comes with a USB-C cable. With the large LCD screen, you always have a clear view, all in one unit that easily slides into your pocket or the included storage case.
