The laser level can emit 16 visible horizontal, vertical and inclined laser lines separately or simultaneously for automatic leveling. Equipped with self-test calibration function, ≤3° automatic leveling, but if the angle is over 3°, the laser light will keep flashing and the laser level will make a beep sound to remind you to reset them on a flat ground. It provides accurate horizontal and vertical data for indoor construction stakeout and calibration, easy to use and versatile. Suitable for floor tile layout, paneling, wallpapering, stenciling, wainscoting, finish carpentry, wall stud layout and partition installation. Features: Compact Size: Lightweight and portable, long-lasting ABS housing makes this laser level perfectly shock resistant, wear resistant and impact resistant. IP54 waterproof and dustproof. Millimeter-level Laser Sources: Using 4 high-precise millimeter-level green laser line laser sources, with higher brightness, strong penetrability, adjustable thickness and brightness, and the light is clearly visible both indoors and outdoors. Accurate Positioning: One button power on/off. It can output 16 visible laser horizontal and vertical lines separately or simultaneously for finer positioning, with 3° self-leveling system, high flexibility and stability. 3° Automatic Leveling: Equipped with self-test calibration function, ≤3° automatic leveling, but if the angle is over 3°, the laser light will keep flashing and the laser level will make a beep sound to remind you to reset them on a flat surface. Tilt Mode: It has a tilt mode, you can place the laser tool at any angle to make tilt lines, the line will not flash and will not promote beeping sound. Laser Quantity & Brightness Adjustable: Touching panel, convenient for you to control the laser quantity and laser brightness, which makes it suitable for both indoor and outdoor use, with continuous laser and pulse laser. And also support pulse laser under tilt mode. High Extensibility: The bottom of the laser level is reserved with 1/4inch screw thread for easy connection, it can also be used with tripod (not included) by 1/4inch to 5/8inch threaded rotation base (included) or 1/4inch to 5/8inch adapter (not included) to adjust the working height of the machine. Stylish Remote Controller Design: Ergonomically designed buttons on the remote controller, wear-resistant, with high sensitivity line mode switching and line brightness adjustment, and with a comfortable grip feel. "V"=vertical line, "H"=horizontal line, you can easily adjust the amount of laser lines by briefly pressing "V" or "H"; and long pressing "V" to decrease luminance and long pressing "H" to increase luminance. 7mm Wall-mounted Bracket: The T-shaped bracket with 7mm wall mounting distance, which has 360° rotatable fine adjustment mechanism, up and down angle regulation and 47mm fore-and-aft regulation distance, all the structures can make the machine quickly find the target (1/4 inch screw size). Lifting Platform: The laser level lifting platform is height adjustable design, max 65mm adjustment ranges, anti-slip texture design for increasing friction, more stable placement. Window Clip: There is a window clip holder for working with the wall-mounted bracket, with 27-36mm wide clamping ranges, suitable for a variety of laser levels. Carrying Bag: Comes with a EVA cloth bag, wear resistant and impact resistant, easy to carry, providing quick and convenient mobility and storage in a complex environment. Note: Please do not let the laser line shoots your eyes directly, and do not stare directly at the laser light. The laser output maker is located at the output hole. Do not disassemble the instrument and perform your own internal repairs. The instrument meets laser radiation safety rating standards.
