This cross laser level comes with a convenient PRO-STACK™ carrying case, a target, safety glasses, a multi-mount, a 7.2V 2Ah Li-Ion battery, and a charger. It offers a line range of 30 meters (up to 50 meters with a detector) and an accuracy of 3 mm at 10 meters. It projects a horizontal and then a vertical line forming a cross, with a 150° angle for an extended line return onto the ceiling. Its pulsed mode allows for outdoor use with a detector (not included), while its reinforced casing and IP54 protection ensure optimal resistance to dust and splashes. The compensator lock is easily engaged via the on/off button, and its compatibility with 1/4" and 5/8" threads guarantees versatile installation, making this laser a reliable, robust, and practical tool for all your alignment and leveling tasks.
