1. Measurement range 2. Measurement accuracy 3. The fields used are basically divided into the following situations:
a) Only need to measure the distance within a few meters or more than ten meters, and the accuracy requirements are not high. *Recommendation - "Ultrasonic Range Finder" is optional. However, due to the low accuracy and great environmental impact, the ultrasonic rangefinder has been eliminated in China at present. *Remarks - The measurement effect of the ultrasonic rangefinder is greatly affected by the environment, and the stability and directionality are worse than that of the laser rangefinder, but the price is relatively cheap! Suitable for indoor measurements.
b) The measurement distance is not long, and it is mostly used indoors, with high precision requirements! *Recommendation - Optional "Handheld Laser Rangefinder" available. *Recommended - Hong Kong CEM brand laser rangefinder *Remarks - The handheld laser rangefinder is most suitable 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 expected range and effect.
c) The measurement distance is far, and it is mostly used for outdoor use! *Recommendation - buy "telescopic laser rangefinder". (ie: a laser telescope rangefinder)! *Features - both a telescope and a rangefinder! With multiple observation magnifications, the user can easily aim at the target for distance measurement only through the cross sight system inside the eyepiece! Using the transparent infrared laser emission and reception that is harmless to the eyes, the target distance can be accurately measured, and its size is small, light and easy to carry.
d) The measurement distance is long, outdoor use, and the measurement accuracy is high!
