· Under favorable conditions (good target surface and room temperature), up to 10m (33ft).
· Under unfavorable conditions (bright sunlight, a very weak reflecting target surface, or large temperature fluctuations),
the error can increase by to ± 0.25mm/m (± 0.003 in/ft) for distances over 10m (33ft).
