Why Bosch GLL 30 Blinking Is Necessary

This blinking acts as an immediate alert, preventing me from relying on inaccurate measurements that could compromise my work.
Additionally, the blinking helps me maintain proper alignment. If the line isn’t steady, I know right away that I need to adjust the device or check its positioning. This feature saves time by avoiding guesswork and re-measuring later. Overall, the blinking is a small but essential signal that keeps my projects precise and professional.
