Laser Distance

Range: 0.3ft-131ft (0.1m-40m)

Resolution: 0.04inch(1mm)

Accuracy: ±1/16in (±2mm) in ideal circumstances*

*Non-ideal circumstances such as outdoor with strong light, or under the bad reflective surface, the error will be superimposed with maximum +- 1‰ of the measurement distance.

Scale Rolling Ruler

Range: 0-300feets (0-99meters)

Resolution: 0.04inch(1mm)

Accuracy: ±1mm or ±0.2% in ideal circumstances.**

**Non-ideal circumstances: The accuracy decreases on slippery, uneven, soft, curved surfaces. Inclination, misalignment and other human error factors will also affect the measurement accuracy.
