Magnetic digital level protractor with interchangeable relative and absolute measurements Relative/absolute measurement interchange at any location, enabling quick reference or orientation checks as needed. Magnetic design allows easy attachment to metal surfaces for stable, hands measurement. Clear, fast readings on a large display Electronics tools feature a large LCD screen that quickly shows measured values for easy reading in various lighting conditions. Provides precise angle and level information at a glance to streamline setup and verification tasks. Builtin bottom surface mounting for convenient use Digital angle finder includes a builtin mounting surface on the bottom for easy attachment to object workpieces. Enables hands measurement and stable positioning during alignment, squaring, or setup. Portable, versatile measurement tool Compact, portable digital angle gauge that can be used in combination with other measuring tools. Expands the measurement range when used in conjunction with additional instruments, improving versatility on the job. Use scenarios Cabinet or shelf installation: attach the tool to a metal frame or support, switch between absolute and relative measurements to ensure the entire installation is level and plumb. Machine setup or fixture alignment: mount on the workpiece to capture precise angles and reference points, then crosscheck with other gauges for accurate alignment. Tile, countertop, or panel work: use the large display to verify level surfaces across panels, expand measurement capability by combining with other tools as needed.
