Feature:1. [Self-Leveling \u0026 Manual Modes] Automatic self-leveling and manual modes are applied on this 50 ft green beam laser level for construction and renovation. The smart pendulum system ensures level line to be projected on rough surface. By the designated button, automatic self-leveling and manual modes can be switched easily.2. [Wide Ranges of Lasers] Crossline green beam laser is applied on this self-leveling laser level with the ranges of 150 and 130 for vertical and horizontal lines respectively. The wide ranges of laser lines are helpful for you to work on your projects in most areas.3. [High quality Design \u0026 Magnetic L-shape Bracket] The red beam laser level device is designed with IP54 protection (Splash \u0026 Dust) for some outdoor and hazardous working conditions. The laser level tool comes with a 360 rotatable magnetic L-shape bracket with a mounting thread of 1/4 to make laser level device can be mounted on an auxiliary tool and be hanged on magnetic objects.4. [Brightness Adjustment \u0026 Improved Accuracy] Brightness pulse stepwise adjustment are designed on this laser level tool for different working contexts and protect the eye. The laser level projects brighter green beam with an accuracy of 2 mm/15 m to make your projects can be done precisely.5. The eye protection function is adjusted by pulse gradual change of strong and weak light, and can adapt to various working scenes at the same time: A. Press V for a long time to thin the light, and the bright spot gradually weakens, which is suitable for close work. For example, the wall tiles and floor tiles are equal to the light, and the weak light can be used for close construction. The advantage is that the eyes will not have irritating pain, but also save electricity and prolong the service life of the laser head; B. Press H for a long time to thicken the light, and the light will become stronger gradually. If you can use strong light for long-distance construction, it will be clearer and brighter.Specification:Features:[Self-Leveling & Manual Modes] Automatic self-leveling and manual modes are applied on this 50 ft Green beam laser level for construction and renovation.
