The construction target RS40 permits documentation and permanent security of heights and axis with a single product. If different measuring devices are used at a construction site, the combination markers are the best solution to avoid measuring differences. The height, axis and position number are indicated with number punch or waterproof marker pen. Leveling instrument, laser, theodolites, or total station: the combined markers are the perfect surveying point for any instrument! On difficult ground, the markers are permanently fastened with adhesive, or with dowels and screws. A protrusion to which the measuring rod or a measuring slat can be applied guarantees precise transfer of height. Crosshairs are imprinted on the backing plate under the exact center of each reflective target to ensure the survey point is durably marked. If the reflective target is damaged at any point, it can easily be replaced, and the original survey point can be restored quickly, easily, and cheaply.
NOTE: Survey markers with crosshairs, and without reflective targets, are available for the use of leveling instruments, theodolites, and construction lasers.
