Product description Battery-operated multi-line laser with green laser A self-levelling multi-line laser with two green horizontal and one vertical lines that can be used separately or together. The laser is dust- and water-resistant with IP54 rating. Memory mode function: when the power is switched on, the laser beam will have the same mode as the last time before it was switched off. Also works with 8 x AAA (ADP09) batteries. Compact and lightweight design The eXtreme Protection Technology (XPT) ensures good dust and water resistance. Designed for use in harsh environments Battery protection system automatically switches off power when battery level is low Even power-hungry green laser lines can continue to be projected during prolonged continuous use Rotating base with eccentric rotation mechanism reduces set-up time Vertical laser lines can rotate up to 10° left and right around the defined plumb point (with a dial for fine adjustment). The eccentric rotation mechanism allows the laser housing to rotate without changing the position of the defined plumb point on the ground, allowing easy line positioning. High-brightness green laser for increased visibility in bright work locations or outdoors. Even green laser lines that consume a lot of energy can continue to be projected during long-term continuous use.
