4x90/2x180°(0.01°) Digital Angle Finder with Dual Laser Digital Angle Gauge with Bottom and Back Magnetic Rechargeable Inclinometer with Digital Level Bubble (Class 2 Laser, <1mW Power Output)

2-Strong
Magnetic Base: With built-in magnets on both the bottom and back, angle gauge provides a stable, hands-free operation. It can easily attach securely to any metal surface like pipes, studs or appliances. 2 included self-adhesive steel strips allow stable mounting on non-magnetic walls. This hands-free mounting enhancing safety and efficiency without requiring an additional bracket
Rechargeable with Smart Measurement Modes digital angle finder features a USB-C rechargeable battery (650mAh, ~6h laser use) and supports both relative/absolute angle measurement. Essential smart features include auto power-off, low battery warning, data hold, zero setting, user calibration, and multiple unit conversion (°, %, mm/m, IN/ft), ensuring reliable operation and power management for father's DIY or jobsite projects
Calibration GuidanceFor ± 0.1 ° accuracy, you calibration function must be performed correctly. This requires a flat, stable surface with less than 5° of tilt; exceeding this causes an "Err" display. Digital angle gauge must remain completely still during calibration.
Note: Successful calibration replaces the original factory data with the user's settings, so this function should be used carefully only when recalibration is necessary for sustained precision
Note: Please remove the transparent protective film on the screen before use
