Feature: 1. High accuracy, precise positioning of the vertical line, reducing errors and improving work efficiency. 2. Through strict balance test, the pendulum can be stable and accurately leveled even if it vibrates randomly. 3. Low refraction, good light transmission, using optical glass, high light transmission and no other variegated colors. 4. The equipment will be self‑leveling, put the line level on a more level place, and automatically level within an inclination of <4°. 5. Multiple protection performance is more stable, protection grade IP54. Suitable for wall construction, photo hanging, etc. 6. The green beam has strong penetrating power, clear eye protection, no blur, no dazzling. The locking mechanism protects internal parts and allows manual mode.
