3d green line laser, rechargeable self leveling laser level for construction, usb charging auto leveling 3 plane level kit with 12 lines, 360 degree alignment laser leveler tool, laser level: class ii wokeline <br>the green laser lines projected by this unit are clearly visible up to 130 feet indoors, and <br>outside with the laser receiver in use the effective range is up to 165 feet. the self-leveling <br>smart pendulum system keeps the lines level when in unlocked mode with the unit <br>anchored using the magnetic base. if the unit becomes out of level for any reason, an <br>alarm will indicate that the base and unit should be checked. when the pendulum system <br>is locked, the multifunctional unit can be safely transported or used to project square lines <br>at any desired angle. <br> <br>the coated laser reticle provides improved laser clarity and prevents reflections that could <br>especially affect outdoor use in bright light. the 520nm wavelength lasers are accurate to <br>1/16 inch at 30 feet, providing for true and level lines throughout all projects. <br> <br>the laser comes with two long-lasting batteries and a charger that includes a usb charging <br>port for convenient charging of other devices. <br> <br>this unit provides the same functionality of other 3x360 degree units at about half the cost. <br>the manufacturer provides a 5-year warranty on all the parts of this laser unit. <br> <br><b>specifications:</b> <br>self-leveling range: ±4° <br>accuracy: 1/13in. at 33ft(2mm/10m) <br>number of lines & range: 12 lines, 360°×3 <br>wgr12l wave length: 520nm(green laser) <br>laser safety class: laser power: ≤1mw. class ii. <br>working range: 65 ft.(20m) or 165 ft.(100m) with detector <br>power range: 7.2v-2000mah/ li-ion battery <br>wgr12l operating time: 6 hours <br>operating temperature: 14 to 113?(-10? to 45?) <br>waterproof/ dust level: ip54 <br>dimensions: 5.1×3.5×4.7in.(129x88.5x120mm) <br>net weight: 1.21lb./ 0.55kg
