A hammer and a concrete chisle is a good solution for marking the ends of a calibration course. If the calibration course has a curb it is a good idea to mark either the top part of the curb and/or the vertical part of the curb as well as on the chisle marks of the ends of the calibration course so that you can find the ends of the cal course easily. Then you can look for the chisle marks. If you are lucky you may even see some of the paint in the chisle marks.
