Product Feature And Application
150-meter laser pointer
- Co-focal, coaxial, visible laser dot; the laser beam is directed directly at the target point
- 150-meter range, suitable for long-distance operations
- When the laser pointer is aligned with the crosshairs of the telescope and both are in focus and on the same axis, the position indicated by the laser dot is the target point to be measured.
No calibration required for the laser
- The lower laser is mounted on a vertical shaft, making it difficult to shift out of alignment, which resolves the issue of the lower laser drawing circles on the ground due to misalignment.
Encoder-based angle measurement technology
- No initialization required upon startup; angle data is automatically saved when the device is turned off
- No need to worry about data loss even if the device is turned off due to a power outage during extended outdoor use
