This pocket-sized digital level can do measurements and calculations in areas where larger levels can't fit.
Used by professionals it has a high rate of accuracy and displays and converts angles in degrees (°) or slopes (%) , millimetres or metres, inches or feet, without the need for calculations.
It has a pause function that allows the user to hold a reading on the display, which is handy when your measuring an angle in an area with difficult access and can't read the level - which is why orthopedic surgeons have used it during operations.
The display reading can invert, which means it reads right-side up when the level is up-side down so it's easier to read.
It is molded in an impact-resistant ABS polymer with built in horizontal and vertical bubbles on an aluminum magnetic base for metal surface attachment.
