Milwaukee 50 Meter Laser Line Detector extends the laser functionality to up to 50 meter indoors and outdoors for fast point-to-point alignment. The front and back LEDs provide users with high visibility feedback improving the set-up process. Rare earth magnets located on two sides of the detector allow it to easily attach to metal surfaces, ideal for ceiling grid installation. The included material clamp is perfect for setting elevation. The Laser Detector also features adjustable audio and is compatible with Milwaukee Cross Line and Plane lasers.
