contrast display for any lighting Large black and green VA display remains legible in bright sunlight or dim workspaces, allowing measurements to be read quickly without eye strain. Durable, construction with IP54 protection An aluminum housing provides wear resistance, while IP54 dust and water resistance protects internal sensors for reliable performance in harsh environments. Precision 4x90 degree digital angle measurement Achieve accurate multiangle readings with a precision of ±0.1° at 0° and 90°, ±0.2° for other angles, and a 0.05° resolution. The unit can zero at any angle for quick comparisons. 4Side strong magnet and autoinvert display Magnets on all sides secure the finder to table saw cutters, metal surfaces, and DIY tools for slip measurements during cutting and leveling. The display autoinverts for easy reading when placed upside down. Practical use scenarios Woodworking and furniture making: set miter and bevel angles, verify squareness of joints, and transfer angles during cabinet assembly. Construction and installation: check level and plumb for countertops, doors, and tile transitions, and transfer angles across fixtures. Metalworking and DIY projects: align cuts on metal components, secure the finder to equipment for accurate angle measurement during fabrication and adjustments.
