Feature: 1. 1. High Precision with 4D 16-Line Positioning: Equipped with a 4D 16-line positioning system for more precise and detailed work, ideal for both horizontal and vertical alignments in interior construction. 2. 2. Automatic Self-Leveling System: Features an advanced self-leveling mechanism that ensures accurate readings within ±3°, making it incredibly easy to use even for beginners. 3. 3. Versatile Use; Adjustable Extension Pole: Comes with an adjustable extension pole (3 height settings) compatible with most 5/8" laser level interfaces, enhancing its versatility across various applications such as tiling, paneling, wallpaper hanging, and stud framing. 4. 4. Compact & Portable Design: The compact design, coupled with a carrying case, makes this laser level easy to transport and store, perfect for professionals on the go or DIY enthusiasts working in multiple locations. 5. 5. High-Quality Laser Diodes & Precise Mirror: Utilizes top-grade laser diodes alongside high-precision conical mirrors to produce clear, bright, and highly accurate laser lines, with adjustable brightness for optimal visibility under different lighting conditions. 6. 6. Self-Calibration & Safety Alerts: Incorporates a self-check calibration function. If the unit is placed at an angle greater than 3°, the laser will flash continuously, and the device will emit a warning beep, prompting the user to reset the instrument on a flat surface, ensuring safety and accuracy in every project.
