Introduce：
This Laser Rangefinder Telescope is able to measure the distance as by emitting invisible,
eye safe, infrared energy pulses to the target and instantaneously calculates ranges by
measuring the time it takes for each pulse to travel from the rangefinder to the target and
back.
Rangefinders are used in many sports, recreation and commercial environments.
Rangefinders ability to measure the distance to a target is determined by the size, colour
and reflectivity of the target.
Please strictly observe the following guidelines so you can use the rangefinder properly and
avoid potentially hazardous problems. Before using this product, please refer to the “Safety
