4D 16 lines:< /strong>16 laser lines emitted separately or simultaneously for finer positioning, with a 3 , flexibility and stability. Using high quality laser diodes and high-precision cone mirrors, the emitted laser lines are fine and bright with high precision, and the brightness is high. is adjustable. Automatic leveling of 3:&Equipped; a self-test, self-leveling 3 calibration function, but if the angle is greater than 3 , the laser light will continue to shine. It will flash and the laser level will beep to remind you to reset them on flat ground. Remote control: Delivered With a remote control, H = vertical line, V = horizontal line, and you can adjust the brightness. Switch the laser light easily by pressing the + or - button. Scan the QR code on the back of the remote control to download the APP from the mobile phone, convenient for controlling the laser light. operate the machine level. The laser level is controlled by the application via the BT connection, the brightness Adjustable laser light and voice control function.
