Product Highlights

Engineered to be a comprehensive solution for complex outdoor jobsite leveling, the Bosch GRL18V-34K 18V Rotary Laser Kit delivers high precision with convenient power flexibility to keep the workday moving. Use with either the included 18V 4 Ah battery or C alkaline batteries (sold separately) for extended use or backup power on the jobsite. The intuitive single dial-in slope features an expanded ±15% Y-axis range for more precise results in grading or sloping applications. A simplified bi-color LED display provides clear visual feedback, making it easy to know if the laser has a slope set (red) or is level (green). IP66 rated, the laser is dust-tight and water-resistant for enhanced durability in harsh job site conditions. It’s also tested to withstand a 5 Ft. tripod tip-over for added confidence on the job. Built for precision, the rotary laser has a working range of up to 1,500 Ft. and delivers accuracy up to ±1/16 In. at 100 Ft. in horizontal applications and ±1/8 In. at 100 Ft. in vertical mode. The enhanced self-leveling range of ±15% helps support faster setup on uneven surfaces and reduces the need for manual adjustments. Fully featured with Bluetooth® connectivity, control the setup of the laser from across the room when paired with a smartphone and the free Bosch Leveling Remote App. An all-in-one solution, this kit comes complete with an LR20 receiver, 18V 4 Ah battery, charger, alkaline battery adapter, tripod, grade rod and plastic carrying case.
