Berntsen Monitoring Retro Reflective Surveying Targets with 40 x 40 mm Target

For quick positioning with tachymeter and all common measuring devices.

Ranges:

Target reflectors with cross hair 30 mm x 30 mm: range approx. 80 m (262 ft)*
Target reflectors with cross hair 40 mm x 40 mm: range approx. 100 m (328 ft)*
Target reflectors with cross hair 60 mm x 60 mm: range approx. 120 m (393 ft)*

*The ranges are average values and will be greatly exceeded by the majority of current total stations, some of them need a minimum distance of 10 meters

Tested temperature rating of -112° F to +212° F

Attention: It is recommended that only reflective targets are used for distance measurements with tachymeters or total stations. Targets with cross-hairs (non reflective) are offered specially for use with auto levels, theodolites and construction lasers.
