These markers can be used in a variety of situations. Inside buildings, heights and axes are clearly documented. The transfer of axes to the next floor can be done easily and accurately by means of laser or plumb line to stairwells or other openings. Outdoors they can be fastened permanently to any desired point. There they can be used for the positioning with the tachymeter or are used as a batter board or for securing the height and axis.
If the markers are fastened to the facade, surveyors and foremen can continue to use them during construction. Facade subcontractors can use them to measure glass or natural stone facades, or as needed. They are also great for 3-dimensional observation of facades, bridges and bulkheads, etc. Crosshairs are imprinted on the backing plate under each reflective target to ensure the survey point is durably marked.
