RS80 markers are used wherever difficult surveying positions would make it impossible to sight the measuring points and are installed in a "roof shape". For the observation of facades and objects, these plaques are very well suited as a corner solution. If heights and axes are to be transferred from outside to inside or vice versa, the markers can be mounted, for example, on the window reveal. You can then literally measure around corners.
