DOVOH Green Laser Laser 4D Laser Level with Auto 2 Vertical Lines and 2 Horizontal Receiver Compatible Y4-360G Level, 4x360° 16-Line Level,

【Convenient Charging Options】This self-leveling laser level 360 has two power options: it can be powered by a USB cable or by a USB cable, which is convenient when the power runs out. The power can be charged within the device. This feature eliminates the need to remove and replace the power, saving time and convenience. 【Auto-Leveling & Manual Mode】This 16-line laser level can automatically level within ±4 degrees when working in auto-leveling mode. It will beep and flash when it is out of the auto-leveling range. When working in manual mode, the laser line can be locked at any angle. [Pulse Mode for Outdoor Use] The laser level supports 360° self-leveling in pulse mode, which works with a 10KHz laser level receiver. In pulse mode with the laser level receiver, the working range can be extended to 197ft/60m. The DOVOH DR1 high-precision laser level receiver is recommended for use with the Y4-360G laser level. Durable Design & IP54 Protection: This green laser level features a durable housing with rubber edges and an aluminum alloy laser hood. It has passed a 1m drop test and can withstand a certain amount of wear and tear on the job site. Its dustproof and waterproof body with IP54 protection rating ensures peace of mind even in dusty environments or sudden rain showers.
