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, 4 automatic leveling, but if the angle is over 4, 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. 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. Output 16 visible laser horizontal and vertical lines separately or simultaneously for finer positioning, with 4 self-leveling system, high flexibility and stability. Equipped with self-test calibration function, 4 automatic leveling, but if the angle is over 4, 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. Digital display control panel design, touching buttons with clear-definition battery power display, convenient for you to know the remaining battery power in real time so that you can recharge or replace the battery in time. 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 (included) to adjust the working height of the machine. Two-way clamped pendulum locking to avoids the displacement of the pendulum, provide evenly force without shaking, stable internal structure, thus significantly improving impact protecting ability. Equipped with a bubble level to help you check whether the laser level is horizontal or not. 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 pulsed laser. "V"=vertical line, "H"=horizontal line, you can adjust the quantity of laser lines easily by press the "V"or "H" button, and long press "V" button to reduce luminance and long press "H" button to increase luminance. 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 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, anti-slip texture design for increasing friction, more stable placement. Comes with EVA carrying bag, waterproof and rainproof, 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.
