A sensing unit comprising of a wheel connected to an indicator provides a magnification of 4:1. Deviation of the surface from a straight-line is shown on a scale calibrated in increments of 2 mm in the 0-10 mm range and 5 mm increments in the 10-25 mm range. It comprises of a manual dye marker which is used to mark irregular surface sections when found.
