The laser level meter can emit 16 visible lase horizontal, vertical and oblique lines for the automatic leveling separately or simultaneously. Equipped with self-test calibration function, ≤3° automatic leveling, but if the angle is over 3°, the laser light will keep blinking 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 operate and versatile. Suitable for flooring tile layout, paneling, wallpapering, stenciling, wainscoting, finish carpentry, wall stud layout and partition installation. Features: Compact size, lightweight and portable, long-lasting ABS housing make this laser level perfectly shock resistant, wear resistant and impact resistant. IP54 waterproof and dustproof. ​Using 4 high precise millimeter-level green laser line laser sources, with higher brightness, strong penetrability, thickness adjustable and brightness adjustable, and the light is clearly visible both indoors and outdoors.​ One button to switch 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. Equipped with self-test calibration function, ≤3° automatic leveling, but if the angle is over 3°, the laser light will keep blinking and the laser level will make a beep sound to remind you to reset them on a flat ground. It features a tilt mode, you can place the laser tool at arbitrary angle to make tilt lines, will not flash the line and will not promote beeping sound. The rational layout panel has a clear-definition digital battery-powered screen, which makes it easy to control the amount of laser light and the laser line brightness, and you can replace the battery and recharge it at any time. Support adjust the quantity of laser lines, and adjust the laser lines' 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. "V"=vertical line, "H"=horizontal line, you can adjust the quantity of laser lines easily by short press the "V"or "H", and long press "*" to reduce luminance and long press "H" button to increase luminance. The bottom of the laser level reserved with 1/4inch screw thread for easy connection, it also can be used with tripod (not included) by 1/4inch to 5/8inch thread base (not included) or 1/4inch to 5/8inch adapter (included) to adjust the working height of the machine. Stylish remote controller design, ergonomic buttons designed on the remote controller, wear-resistant, with high sensitivity line mode switchment and line brightness adjustment, and with a comfortable grip feel. The T-shape bracket with 7mm wall mounted distance, which has 360° rotatable fine adjustment mechanism, up and down angle regulation and 50mm fore-and-aft regulation distance, all the structures can make the machine quickly find the target (1/4 inch screw size). The laser level lift bracket is height adjustable design, max 65mm adjustment ranges, anti-slip texture design for increasing friction, more stable placement. ​There is a window clip holder for works with wall-mounted bracket, with wide clamping ranges, suitable for a variety of laser levels. Comes with a plastics box, 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. The laser output maker is located at the output hole. Do not stare directly at the laser light. Do not disassemble the instrument and perform your own internal repairs. The instrument meets laser radiation safety rating standards.​ Specifications: Name: Laser Level Main material: plastics+metal Battery: 2 * rechargeable lithium batteries, 3.7V, 2400mAh (included) Line type: 4 * 360°, 16 lines Wavelength: 532nm (Green) Self-leveling angle: ±3° Wall mounted distance: 7mm Operating temperature: -5℃ to 50℃ Working ranges: about 20m in diameter Waterproof: IP54 Level machine size (assemble with battery): 114 * 135 * 135mm / 4.49 * 5.31 * 5.31in Rotation base: 97 * 83 * 75mm / 3.82 * 3.27 * 2.95in Lifting platform size: 113 * 92 * 30mm / 4.45 * 3.62 * 1.18in Wall mounted bracket size: 160 * 83 * 75mm / 6.30 * 3.27 * 2.95in 1/4inch t
