USB Rechargeable Green 3-Point Laser. The MILWAUKEE® USB Rechargeable Green 3 Point Laser is powered by REDLITHIUM™ USB, delivering all-day runtime and uncompromised visibility. The high-intensity laser beams allow the green points to be visible up to 150' for fast, accurate point transfer. The Integrated Adjustable Clearance Bracket enables this 3 point laser level to easily fit over steel stud track or create clearance for marking the floor. The amplified rare earth magnets provide a strong hold onto metal surfaces, while the integrated screw and nail hang holes allow easy and efficient setup in any environment. REDLITHIUM™ USB Batteries can be charged inside the laser via a Micro USB or swapped out with additional REDLITHIUM™ USB Batteries for virtually no downtime.
