Milwaukee cross line laser M12 3PLSKIT-401P

The M12™ green 360° 3-plane laser is a versatile unit with one horizontal and two vertical lines, making alignment, leveling, squaring, and transferring points fast and simple, and allowing for easy layout of large spaces with one tool
The unit uses bright green diodes for best visibility, which are up to 4x more visible than red lasers
Thanks to bright green beams, the working range is 38 m (50 m with receiver).
Runs on M12 B4 battery for all day, 15+ hours.
3-mode pendulum system: manual mode can be used at any angle, self-leveling mode indicates deviations and corrects the line by 4°, and lock mode protects the device's components during transport.
Integrated magnetic bracket with rear amplified rare-earth magnets, ¼″ and ⅝″ tripod thread, and hanging hole allow the device to be attached to steel and wooden posts and a tripod.
The bracket allows the laser to rotate 330° around the vertical point, and the integrated control knob ensures faster point-to-point alignment.
The construction with a robust coating has a protection class of IP54, the laser is water and dust resistant and can withstand drops from up to 1 m height.
Flexible battery system: works with all MILWAUKEE® M12™ batteries.
