Powered by an 18V 4.0Ah lithium-ion battery or C alkaline adapter, this green-beam rotary laser delivers up to 1,500 feet of operating range with the included LR20 receiver, ±1\/16-inch accuracy at 100 feet, a ±15% Y-axis dial-in slope capability, and an IP66 water-resistant composite housing. Equipped with Bluetooth smartphone connectivity, a 5-foot tip-over drop resistance, a 13-foot grade rod, and a heavy-duty aluminum tripod, this rotary transit system establishes precise elevations across civil engineering and excavation sites.\u003c\/p\u003e\n\u003ch3 style=\"color: #004b87;\"\u003eBest Used For:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCivil Earthmoving \u0026amp;
