GLM 40 Laser Distance Measure

A pocket-sized laser distance measure that reads lengths from 0.15 m to 40 m with a typical accuracy of 1.5 mm. Besides straight distance it works out area, volume and indirect height. The lit display shows the last three results and the unit stores the last ten. Its housing is shock-resistant for drops from one metre and sealed against dust and splashes, and it runs on two AAA batteries and switches itself off after five minutes.
