Featuring an advanced green-beam laser diode that projects a line up to four times brighter than standard red beams, this high-performance transit level provides exceptional visibility across long distances, even under direct sunlight. Engineered specifically for massive outdoor grading, concrete formwork alignment, and excavation setups, this system features a streamlined, one-button user interface that eliminates complex menu tracking. Turn the tool on, and its smart internal systems handle the rest, enabling seamless automatic self-leveling so your crew can get to work immediately.\u003c\/p\u003e\n\u003cp\u003eEngineered for maximum versatility on unpredictable terrain, this structural leveling tool features a wide ±15% self-leveling range that ensures rapid, error-free setup on uneven ground. Its heavy-duty composite framework is IP66-rated to be completely dust-tight and resistant to high-pressure water jets, and it has been officially drop-tested to survive a 5-foot tripod tip-over shock. To prevent costly downtime on remote jobs, the laser boasts a flexible dual-source power system, allowing it to run continuously on the included universal AMPShare 18V Lithium-Ion battery pack or standard C alkaline batteries using the provided adapter sleeve. Complete with a heavy-duty tripod, a telescoping grade rod, and a robust laser receiver, this kit provides a 1,000-foot working range with an accuracy of up to ±1\/16-inch at 100 feet.\u003c\/p\u003e\n\u003ch3 style=\"color: #004b87;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra-Bright Green Laser Diode:\u003c\/strong\u003e Delivers exceptional visibility that is up to 4X brighter than classic red lasers, optimizing performance for long-range outdoor layouts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRapid One-Button Interface:\u003c\/strong\u003e Simplified singular button design streamlines setup and operation while full automatic self-leveling eliminates manual calibration errors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Power Flexibility Architecture:\u003c\/strong\u003e Operates seamlessly using the included 18V 4.0Ah battery pack or conventional C alkaline cells for flexible power management.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP66 Environmental Rating:\u003c\/strong\u003e Heavy-duty dust-tight construction shields delicate internal optics from harsh windborne site dust and powerful rain or water splashes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMassive 1,000-Foot Operational Range:\u003c\/strong\u003e Provides dead-on reliability across vast distances with a tight structural accuracy of up to ±1\/16 in. at 100 ft.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAMPShare Battery Compatibility:\u003c\/strong\u003e Part of a cross-brand cordless ecosystem, the included battery works across an expansive array of professional power tools.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"color: #004b87;\"\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e(1) GRL18V-3-31G Horizontal Green-Beam Rotary Laser\u003c\/li\u003e\n\u003cli\u003e(1) EXBA18V-40 18V 4.0Ah Lithium-Ion Battery\u003c\/li\u003e\n\u003cli\u003e(1) GAL18V-40 Fast Battery Charger\u003c\/li\u003e\n\u003cli\u003e(1) BA18-C Alkaline Battery Adapter Sleeve\u003c\/li\u003e\n\u003cli\u003e(1) LR20 Heavy-Duty Laser Receiver\u003c\/li\u003e\n\u003cli\u003e(1) BT170HD Heavy-Duty Aluminum Building Tripod\u003c\/li\u003e\n\u003cli\u003e(1) GR8 Aluminum Telescoping Grade Rod\u003c\/li\u003e\n\u003cli\u003e(1) Impact-Resistant Plastic Molded Carrying Case\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ciframe width=\"1076\" height=\"605\" src=\"https:\/\/www.youtube.com\/embed\/5jXUWiW1kLw\" title=\"New Bosch Rotary Lasers | Bosch WOC 2026\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch3 style=\"color: #004b87;\"\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 56.0714%;
