The laser level can emit visible horizontal, vertical and tilt lines for self-leveling, either separately or simultaneously. It provides accurate horizontal and vertical data for interior construction staking and calibration. It is easy to use and versatile. Suitable for laying floor tiles, panelling, wallpapering, stenciling, paneling, finish carpentry, laying wall studs and installing partitions. You can try it. Features: Compact size, lightweight and portable, allowing quick and convenient mobility and storage with the carrying box. Product 16 laser lines separately or simultaneously for finer positioning, with 3° self-leveling system, flexibility and stability. Using high quality laser diodes and high precision conical mirrors, the emitted laser lines are fine and bright with high precision, and the brightness is adjustable. Equipped with self-test calibration function, self-leveling ≤3°, but if the 39; angle is over 3°, the laser light will keep flashing and the laser level will
