Wireless Green Laser Pointer Presenter

Chongqing Lelang Optical & Electronic Instruments Co., Ltd.

Principle
The unit emits a laser beam that is invisible and safe to the eyes. Then it calculates distances by measuring the time it takes for the laser to travel from the rangefinder to the target and then back again.
&nbsp;
General introduction
Accuracy
This rangefinder is accurate to within +/- 0.3 meters in most cases. The effective operating range is from a minimum of 3.5 meters to a maximum range of 600/800/1000/1200/1500 meters. Please note that the maximum operating range may vary due to the reflective properties of the viewing subject, the size of the viewing subject and the environmental conditions at the time of use. Highly reflective shiny surfaces allow for longer ranges than dull, less reflective surfaces. Larger subjects are easier to measure than small ones. Bright light conditions adversely affect the maximum range of the item. The angle to the viewing subject may also affect the range. Viewing objects at a steep angle will limit the operating range.
