Vulcan's Level

木匠的水平/路華的水平具有超強的校準。

Level of Vulcan is a carpenter's level with a unique, two-stage calibration process. Most carpenter's levels need to be calibrated by putting them on a surface that you already know is level. Level of Vulcan uses a two-stage calibration that takes readings in two different orientations, and can compensate for a surface that's not quite level. This allows you to calibrate it on any stable table top or counter top.
