Features:
With 3° self-levelling system: Equipped with a self-checking calibration function, automatic levelling at ≤3°, but if the angle exceeds 3°, the laser light will continue to flash and the laser level will beep to remind you to reset it on flat ground.
4D 16 lines 360° laser level: Two horizontal lines at 360° and two vertical lines at 360° cover every corner of the room. The green laser level produces 16 laser lines individually or simultaneously for more accurate positioning.
High-visibility green laser: Using high-quality laser diodes and high-precision conical mirrors, the laser lines emitted are delicate and bright, with high precision and adjustable brightness. Press the ‘OUTDOOR’ button, briefly press or long-press the ‘H’ or ‘V’ button to freely adjust the laser brightness according to the working situation.
Comfortable and easy to use: Touch button design, clear division of horizontal, vertical and inclined lines. The buttons are wear-resistant, highly sensitive, can quickly change line modes and are comfortable to hold. The laser level is controlled by APP via a BT connection and also features a power display, adjustable laser brightness and voice control functions.
