Lasers are typically utilized in the early stages of construction, and measurement needs will vary based on application requirements. The Makita 12V max CXT Lithium-Ion self-leveling cross-line/4-point green beam laser (SK106GDWAX) 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 SK106GDZ has a line visibility range up to 115 Ft. and is detectable up to 262 Ft. with a Makita laser detector (sold separately). The SK106GDZ has a bright 525 nm class II green laser with +/- 1/8 In. at 33 Ft. 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-leveling line stability is achieved in up to 3 seconds for increased productivity. For longer run time, all 12V max CXT cordless tools are also compatible with the 12V max CXT Lithium-Ion 4.0 Ah battery (BL1041B). 12V max CXT Lithium-Ion batteries are engineered with a battery protection circuit that protects against overloading, over-discharging and over-heating. Its part of the expanding 12V max CXT series, combining performance with superior ergonomics in a compact size. For users in the 18V LXT battery platform, the SK106GDZ has a power connector port that allows an 18V LXT battery to be used with the power source adapter (ADP05) and adapter cord (adapter and cord sold separately).
