To secure the survey point for a longer period, markings were applied to the carrier plates so that any damaged reflective target can easily be replaced and the original measuring point can be restored quickly, easily and cheaply.

Please note: Survey markers with reflective targets are exclusively recommended for carrying out distance measurements using a tachymeter or total station.
Survey markers with crosshairs, and without reflective targets, are available for the use of levelling instruments, theodolites and construction lasers.
