Up to 45ft (dependent on the lighting conditions) >100 ft with detector * Self-levelling: Minor angular misalignments of ± 4° are compensated automatically. If the angular misalignment is greater, the device does not project any lines. Errors are prevented * Exact 90° angle: Alignment work, such as marking 90° angles, is performed at the touch of a button. You really save time! * Lock function: You can manually switch off the self-levelling using the lock function. The laser line can then be projected at any angle. * Very easy to use: With only two buttons the Leica LINO? L2 is intuitive to operate.
