When purchasing a handheld laser pointer rangefinder, there are two issues to be aware of in order to determine if you can purchase the machine you want:
1. For indoor or outdoor use? Or prefer to be indoors or outdoors.
2. What is the measured distance when measuring?
Handheld laser range finder is mainly divided into 30 meters, 60 meters, 80 meters and 80 meters to 200 meters indoors: if it is pure indoor application, it does not involve the problem of light, the measurement distance is within 60 meters, and the quality is good. . If you are using indoors and outdoors, outdoor (daytime) within 60 meters.
There are three issues that must be considered when purchasing a handheld laser range finder: measurement range, measurement accuracy, and use.
(1) It is only necessary to measure the distance within a few meters or ten meters, and the accuracy is not high. It is recommended to use the "ultrasonic range finder". The effect measured by the ultrasonic range finder is greatly affected by the environment, and the stability and directivity are worse than the laser pointer range finder, but the price is relatively cheap, suitable for indoor measurement.
(2) The measurement distance is not long, and it is mostly used indoors, and the precision is high. It is recommended to purchase a "handheld laser range finder". The handheld laser range finder is best suited for indoor use, and the measurement accuracy and effect are very good. (If the user needs to detect in an outdoor environment, it is recommended to use a professional laser sight and reflector to achieve the desired range and effect.)
(3) The measurement distance is far, and it is mostly used for outdoor use. It is recommended to purchase a "telescope laser range finder" (ie: laser ranging telescope).
