Effortless angle calibration Securely place the digital angle finder on any sawing machine using the magnetic base, quickly zeroing and accurately repositioning for precise duct cuts to improve overall craft accuracy. Precise angle measurement Builtin inclinometer determines angle and gradient percentage; Standard mode automatically records current levels to ensure reliable and repeatable results. Enhanced stability The batterybased solid builtin magnet ensures the angle finder plugs securely to metal surfaces, providing accurate levels, frame and angle measurements. Enhanced flexibility Electronic inclinometer enables seamless switching between angle and gradient units to support both relative and absolute measurements, enhancing accuracy and versatility. 23 practical use scenarios HVAC duct work: align and cut ducts with precise angles on a saw, ensuring proper fit and seal. Woodworking and cabinetry: verify miter and bevel angles on saws for tight joints and accurate assemblies. Metal framing and fabrication: attach securely to metal surfaces for stable angle readings during layout and assembly.
