Big Horn, 14221, Digital Level with Bubble and Memory Function, LCD ScreenFeatures:High Accuracy - Accurate to the ±0.1° at 0° and 90° and ±0.2° from 1-89°; displays angle and bevel readings in degrees, pitch IN/FT, mm/M, and percent slope. Great for roofs, rails, ADA ramps.Dual Functionality - As a true (absolute) digital level and electronic inclinometer/ protractor lets you set or check relative angles between surfaces. Plus, the magnetic bases firmly attach to ferrous metal surfaces like conduit, pipe, steel Construction framing, metal fabrication, and more.Construction - Sturdy solid I-beam aluminum frame, magnets, rubber end caps, and IP54 dust/water splash-resistant protection for harsh working environments.Easy to read even in the dark - Featuring a large, bright LCD display you can easily read the measurements whatever the light conditions. The large, bright LCD display flips so that you can see the reading at whatever angle you're holding the level. Plus, since we craft digital level with Audio indicator functionality, you can achieve the precise level and 90 degrees with your eyes closed.Audio indicator - This level features a large, bright LCD display that flips, so you can easily read your measurements all day and night - even in the darkest spaces.This digital level is a highly versatile leveling tool designed for fast and easy operation.It is designed to be used by carpenters, stonemasons, bricklayers, other building trades workers, surveyors, millwrights and other metalworkers, and in some photographic or video graphic work, particularly in civil engineering applications such as building Construction and steel structure erection for on-site angle alignment and leveling tasks.
