Features: Achieve precise 4x90° measurements with our digital angled finder, featuring industrial strength 4 sided magnets for attachment to pipe, or steel beams with ±0.1° accuracy even in vibrating conditions. Equipped with a sunlight readable LED display and smart USB charging, this magnetic inclinometer maintains clear in direct sunlight while optimizing battery life through auto shutdown functionality. Designed for construction technicians, metal fabricators, and DIYers requiring absolute/relative angled data for overhead installations, machinery alignment, or precise woodworking applications. Perfect for vibrations intensive environments like workshops or construction sites, its shock resistant aluminum alloy housing survives drops and dust exposure during ladder operations or confined space measurements. This multi surfaces digital protractor combines data hold capability with magnetic stability, enabling hands less angled verification across steel beams, and uneven structural frameworks. Specifications: Component: Aluminum alloy Size: Approx.61x61mm/2.4x2.4inch Built-in battery: lithium batteries 400mAh (included) Charging: USB Type C Measurement: 4x90° measurement Installation: Magnetic suction Package Includes: 1pcs Digital Angled Finder note: 1.Please allow 1-2cm errors due to manual measurement, make sure that you donot mind befores you order. 2.Due to the differences between different monitors, the picture may not reflect the actual color.
