Angle measurement: Supports both absolute and relative angle readings for a wide range of projects and applications. This enables you to establish a fixed reference or measure incremental changes quickly and accurately. Easytouse interface: Features a vertical display that simplifies reading measurements and an on/off button for efficient power management. This design reduces eye strain and helps conserve battery life during extended use. Four unit measurement options: The UNIT button lets you switch seamlessly between degrees, % slope, mm/m, and in/ft as needed. This provides flexibility for different standards and tasks without manual conversion. Stable magnetic base: Two powerful magnets at the bottom provide grip on metal surfaces for precise measurement tasks. This delivers secure placement and steadier readings during use. Use scenarios Quick setup and alignment on a metal work surface or machine base: mount the device with its magnetic base, read the angle or slope, and adjust components until the target alignment is achieved. Carpentry or metal fabrication tasks requiring precise angles: measure and transfer angles or slopes on parts, switching units as needed to match project specifications. Onsite installation and mounting: verify mounting angles or incline requirements for brackets, rails, or supports on metal structures, ensuring accuracy before final fastening.
