Super green light, clearly visible indoors and outdoors High-brightness green light technology: adopting German OSRAM light source, the green light has high brightness and fine light, which is still clearly visible under the strong outdoor light environment, and can easily cope with all kinds of decorative scenes. No dead-angle marking: Innovative rotating window design, with multi-line laser (such as 12 lines, 16 lines), to achieve all-round blind spot-free measurement, to meet the needs of multi-dimensional construction of walls, floors, ceilings and so on. Intelligent levelling, convenient and efficient operation Fully automatic levelling: Built-in high-precision sensors, 5-degree automatic levelling range, quickly complete the calibration, reduce manual adjustment time and improve construction efficiency. One-key flash function: long press button can enhance the brightness of light to ensure clear positioning even in bright light environment, especially suitable for outdoor decoration projects. Rugged and durable, adapt to complex working conditions Rubber-coated and thickened body: the body is designed to be drop-proof, waterproof and dust-proof, which is durable and can adapt to complex environments such as construction sites and outdoor decoration. Micro-adjustable rotating base: the base supports up and down micro-adjustment, easy to cope with uneven ground conditions, to ensure the accuracy of measurement. Ultra-long battery life, durable and stable Large-capacity battery: Equipped with digital display giant battery, long-lasting, reducing the trouble of frequent charging, suitable for long-time construction. Dual power and one charging design: some models support dual battery configuration, one charging, one use, to ensure uninterrupted construction. Multi-functional application to meet various needs Slanting line mode: supports the construction of slanting lines such as staircase paving to meet the needs of personalised decoration. Crosshatch square line: horizontal up and down, vertical window design on both sides, easy to realise wall and ground levelling, ceiling and floor precision alignment.
