4x 360° Laser Level16 Lines 3D Fine Positioning Laser Level, 4/8/12/16 adjustable lines, two 360° horizontal lines and two 360° vertical lines for complete coverage of floors, walls and ceilings in the room. 360° coverage and professional variable frequency laser head for increased range and clear light transmission.Green Laser LineThe wavelength of green light is changed from red light, so it emits stronger light which provides a working distance of up to 65 feet for outdoor use. Universal for general use for indoor and outdoor, high brightness green, clear indoor and outdoor, long projection distance, high laser height, clear lines.Auto-adjustment & Remote OperationThe laser lines emitted are thin and bright with high accuracy. The laser level automatically adjusts the balance within ± 3° and keeps flashing and beeping when the auto-leveling range is exceeded. When the laser level is placed in a hard-to-reach position, it can be controlled by the remote control, which allows the laser level to be used at any angle.IP54 WaterproofIP54 protection rating against water and dust ensures the reliability and robustness of the device, even in hazardous environments. The laser level is covered on all sides with 3D soft rubber, resistant to shocks and abrasion.Long EnduranceThe high-brightness green beam is clearly visible in the sun and brighter than the standard red beam.
