Bosch GCL165-42GL Description

The Bosch GCL165-42GL 3.7V Green-Beam Self-Leveling Cross-Line Laser with Plumb Points delivers remarkable power flexibility paired with advanced green-beam technology that projects lines up to 4X brighter than standard red beams. Built for all-day productivity, it runs up to 8 hours on the included rechargeable 3.7V Li-Ion 3.0 Ah battery, or can be powered by AA batteries (sold separately) for added versatility on the job. The USB-C charging cord provides the convenience of charging the tool even while it is in use. Built-in VisiMax technology monitors temperature and power consumption to maximize line brightness, optimize energy efficiency, and extend tool longevity. IP65-rated and wrapped in full rubber overmold housing, the GCL165-42GL is engineered for dust-tight and water-resistant durability in demanding jobsite conditions. A Smart Pendulum System self-levels within 4 degrees, blinks to indicate out-of-level conditions, and locks when switched off for safe transport. The fine adjustment knob and pivot rotation allow the laser to rotate around the plumb point for precise point-to-point alignment. With a working range of up to 100 Ft. and 1/8 In. accuracy at 30 Ft., it also supports range extension up to 330 Ft. when used with a compatible receiver (sold separately).
