The Milwaukee REDSTICK Digital Level is one of the first mainstream box level products to have only digital feedback (no ‘spirit vials’). Featuring an innovative and user-friendly interface, the REDSTICK digital levels are the most accurate levels on the market. The circular display is well designed, super easy to read, and can be read from the side and the top. The audio signals add a level of intuitiveness to these levels. The digital signal tolerances can be adjusted, so if you want something “close” to level, it will let you know when you get there.
