Comprehensive functionality: equipped with HOLD and forZero buttons to help you lock in measurements and quickly reset to a true zero, improving accuracy and reducing rework. Easy to read display: a vertical screen provides clear angle visibility, making it suitable for use in tight spaces and for both professionals and DIY enthusiasts. Four measurement units: toggle between degree, percent slope, millimeters per meter (mm/m), and inches per foot (in/ft) using the UNIT button for flexible application across tasks. Magnetic base for stability: builtin magnets secure the meter on metal surfaces, allowing hands operation and reliable readings during use. Clear, practical design: focused on reliable performance, straightforward operation, and consistent measurements in everyday work environments. Use scenario: woodworking and cabinetry installation Align shelves, doors, and countertops quickly and accurately, ensuring plumb and level results without constant remeasuring. Use scenario: tile and masonry work Check slope and angles for drainage or layout, enabling precise tiling lines and consistent results. Use scenario: metal fabrication and machinery setup Set up and align components on metal surfaces with a stable magnetic base, achieving accurate angles during assembly and calibration.
