Dual Power Supply Laser Distance Meter

1. Three Range Options
843E (50m), 843F (70m), 843G (100m) – choose the right model for your application.

2. High-Frequency Green Laser (843G Exclusive)
Brighter and more visible than red laser – works better outdoors and in bright lighting conditions.

3. Dual Power Supply System
Operates on 3× AAA batteries OR a 3.7V / 850mAh rechargeable lithium battery – maximum flexibility on the job site.

4. High Accuracy
±(5mm + d×1/10000) precision – reliable for professional construction, interior design, and real estate measurement.

5. Voice Broadcast
Audible measurement readout – convenient for solo work, overhead measurements, or low-light environments.

6. Electronic Angle Sensor (Inclinometer)
±90° measurement range – enables indirect height measurement and Pythagorean functions.

7. 99-Transaction Data Storage
Saves up to 99 measurement records for on-site comparison or post-work documentation.

8. Multiple Measurement Modes
Supports continuous measurement, area/volume, hook stock (Pythagorean), addition/subtraction, area/volume addition/subtraction, and max/min value tracking.

9. Three Measurement Reference Points
Switchable between front-end, mid-end, and end-end benchmarks – adapts to different measuring scenarios.

10. Self-Calibration Function
Allows user calibration to maintain accuracy over time.

11. Delay Measurement Setting
Set a timed delay to prevent vibration-induced errors – ideal for unstable or hard-to-reach positions.

12. Auto Power Management
Laser auto-off after 20 seconds; device auto-shutdown after 150 seconds of inactivity – preserves battery life.

13. Clear Display & Durable Build
43×35mm backlit display for easy reading. Body size 118×52×27mm, weight ~132g, black + orange color.

14. Optical Lens
Enhanced laser beam quality for more consistent and accurate targeting.

15. Low Voltage Prompt
Alerts user when battery power is low – prevents unexpected shutdown during critical measurements.

16. Unit Switching
Easily toggle between metric and imperial units as needed.
