Magnetic attachment: A strong magnet securely attaches to metal surfaces, enabling hands measuring and improving measurement accuracy in confined spaces or when you need to work with both hands . Dual measurement modes: Provides both relative and absolute measurement options, making it versatile for a range of tasks such as angle measurement and slope checks. Angle and slope conversion: Quickly switch between angle readings and slope percentages to match the format required for different projects, saving time and reducing conversion errors. Data lock function: The data lock freezes the current measurement on the display, allowing easy reading, documentation, and sharing without interrupting your workflow. 23 practical use scenarios Scenario 1: Installing metal shelving or framed panels. Attach the device to a metal surface using the magnet, measure level and angle hands, and lock the reading to mark precise drill points without stopping work. Scenario 2: Woodworking and carpentry. Use the angle mode for bevel cuts and switch to slope percentage as needed for project drawings, ensuring cuts and layouts match required specifications. Scenario 3: Onsite inspections and slope checks. Verify incline or ramp angles on site, switch between relative and absolute readings for different reference points, and lock measurements for clear reporting.
