Lasers are typically utilized in the early stages of construction and measurement needs will vary based on application requirements. The Makita 12-Volt MAX CXT Lithium-Ion Self-Leveling Cross-Line Green Beam Laser (SK105GDNAX) gives the user a cordless solution for selectable horizontal/vertical cross reference lines required for level, align and plumb applications. Depending on ambient light in the working environment, the SK105GDNAX has a line visibility range up to 115 ft. and is detectable up to 262 with a Makita Laser Detector (sold separately). The SK105GDNAX has a bright 525 nm class II green laser with plus/minus 1/8 at 33 for best-in-class accuracy. The laser line fan length spans past the 90 position to provide 180 horizontal and 160 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 12-Volt MAX CXT cordless tools are also compatible with the 12-Volt MAX CXT Lithium-Ion 4.0 Ah battery (BL1041B). 12-Volt 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 12-Volt MAX CXT series, combining performance with superior ergonomics in a compact size. This also comes with a LD080P Laser Distance Measure, 262'.
