The Ermenrich Reel GK100 laser distance meter measures distances from 0.05 to 100 m and calculates areas and volumes. The Pythagorean function allows you to calculate distances using two intermediate measurements, while addition and subtraction support further calculations. Results are displayed on a three-line screen and stored in memory in up to 20 groups.

The horizontal bubble level makes alignment easier, while the audible indicator and low-battery indicator provide updates during use. It is powered by AAA batteries and switches off automatically to save energy.
