Extremely Long Working TimeThe Laser Level is equipped with a 3.7V 7.5Ah (27.75Whr) lithium-ion rechargeable battery providing over 20 hours of continuous operation ensuring uninterrupted work sessions.Greater Visibility and AccuracyUtilizing the latest diode technology the green laser level offers four times better visibility and increased accuracy. In pulse mode it can be used with a detector to maintain full brightness and extend the range up to 196ft/60m under 20000lux illuminance (receiver not included).Self-Leveling Laser LinesThe self-leveling laser level provides 3x360° laser lines one horizontal plane and two vertical planes allowing parallel alignment on floors ceilings and walls. It ensures complete room coverage with one horizontal and two vertical lines.Automatic Self-LevelingFeaturing exact alignment with the Osram laser diode the device self-levels within 4 degrees using a single button for easy mode selection. Automatic self-leveling guarantees fast and error-free work in just a few seconds with a leveling accuracy of ±3mm at 10m.Durable and Waterproof ConstructionHoused in a robust casing the laser level is IP54-rated for waterproof and dustproof protection ensuring reliable performance in challenging environments.
