Note*:
In favourable conditions (optimal target surface, room temperature) up to 10 m (33 ft). in unfavourable conditions, such as intensive sunshine, very weakly reflecting target surface, or large temperature fluctuations, measuring accuracy may deteriorate to approximately ±0.25 mm/m (±0.003 in/ft) for distances above 10 meters (33 feet).
