Great for backsights, check shots, elevation references, and monitoring situations, ‘Smart from the Start’ Rothbucher System markers are the best way to take advantage of your investment in high tech survey equipment. Save crew time, keep employees out of danger, get better data, and feel more secure about construction layout: can you afford not to use Rothbucher System markers?
Target Reflector Ranges:
Target reflectors w/ crosshair 20 x 20 mm: range approx. 50 m (164 ft)
Target reflectors w/ crosshair 30 x 30 mm: range approx. 80 m (262 ft)
Target reflectors w/ crosshair 40 x 40 mm: range approx. 100 m (328 ft)
Target reflectors w/ crosshair 60 x 60 mm: range approx. 120 m (394 ft)
Target reflectors w/ crosshair 220 x 220 mm: range approx. 500 m (1640 ft)
The ranges are average values and will be greatly exceeded by most current measuring instruments. A minimum distance of 10 m is required for some instruments. Survey markers with reflective targets are exclusively recommended for carrying out distance measurement using EDM's or total stations.
Smart Targets with crosshairs and without reflective targets are available for the use of leveling instruments, theodolites and construction lasers.
