2-in-1 Multifunctional Tool: Discover the perfect combination of a ruler and a protractor for simple and precise measurements. Use this tool as both a digital and a traditional protractor to measure all angles in the workshop. The digital angle gauge features laser-engraved metric and imperial graduations on the edge of the ruler, providing a clear and accurate reading. It allows you to simultaneously measure angles and lengths, making it ideal for woodworking, construction, and drafting. Lightweight and Durable with LCD Screen: This digital angle finder is made of tempered glass/reinforced nylon composite, a high-performance material offering excellent rigidity and increased impact resistance. It combines exceptional rigidity, excellent wear resistance, and dimensional stability. Its large LCD screen makes it easy to read angular and linear measurements, eliminating any guesswork when estimating angles or lengths. 360° Inversion: This innovative digital protractor features a bidirectional inversion function. Simply position the gauge on the surface to be cut, lock it instantly with its knurled, non-slip ring, and then mark the measurement. Its instant memory screen automatically freezes the measurement for precise transfer to your miter saw.
