Bosch GPL 3 Self Leveling 3 Point Laser - GPL 3

 

Three-point plumb and level point projection laser accurately transfers and aligns plumb up/down, front level and align points; accuracy is +/- 1/4 In. at 100 ft. There's no waiting for a standard plumb bob to stop moving thanks to a quick-settling pendulum. Smart Pendulum System self-levels, indicates out-of-level condition and locks when switched off. Compact design allows the unit to go anywhere and can be used in almost any interior application. Multi-purpose attachment positions the mount with magnets, strap or threaded mounts (5/8" to 11, 1/4" to 20).
