Precautions:

1. This rangefinder is designed for long-distance measurements, with a minimum measurement distance of 5 meters.

2. Glass can reflect the laser beam and affect measurement results. Do not measure through glass during use.

3. In low-light conditions at night, additional lighting is required to view the readings, as the eyepiece display is not illuminated.

4.It supports 6x magnification, turn the eyepiece knob to achieve optimal clarity.

5.Rain, fog, and dusty conditions may obstruct laser transmission and affect the maximum measurement distance.When measuring objects, select light-colored buildings as the farthest target as possible. Complex vegetation on mountains can obstruct the reflection of laser signals.

Please review these precautions for the rangefinder. We recommend retesting the device outdoors on a target exceeding 5 meters. If you have further questions, feel free to contact us again, and we will respond promptly.
