The MILWAUKEE M12 Green 360˚ 3-Plane Laser w/Automatic Alignment & Receiver Kit provides Automatic Alignment & 70% Brighter Lines* for a faster, more accurate layout onsite. With the kitted Receiver, you can Automatically Align your Laser up to 125’, making the layout of long runs more efficient.  In boosted mode, the 3642-21 is 70% Brighter than our current 3632-21 providing better visibility when it's needed. You will get 10+ Hours of Runtime in Standard Brightness, and 6+ Hours of Runtime in Boosted mode when paired with the 4.0 XC battery pack. You can adjust the brightness and put the laser to sleep from the receiver which is ideal for saving power during breaks. The three 360° planes include horizontal and two vertical lines for fast and easy alignment, leveling, squaring, and transfers allowing you to easily layout large spaces with one tool. The integrated bracket features amplified rare earth magnets that provide a strong hold and will not slide on steel studs, while an integrated hang hole makes setup easy and efficient in any environment.
