The Makita 10.8V/12V MAX CXT Lithium-Ion Self-Levelling Cross-Line/4-Point Red Beam Laser (SK106DZ) gives the user a cordless solution for selectable horizontal/vertical cross reference lines plus 4-point required for level, align, plumb, and square applications. Depending on ambient light in the working environment, the SK106DZ has a line visibility range up to 25m and is detectable up to 80m with a Makita Laser Detector (sold separately). The SK106DZ has a bright 635 nm class II red laser with ±0.3 mm/m = ±3.0 mm at 10m for best-in-class accuracy. The laser line fan length spans past the 90 degree position to provide 180 degree horizontal and 160 degree vertical lines for full reference line coverage. For increased efficiency, self-levelling line stability is achieved in up .
