When buying a laser range finder, there are a few things to consider:
1. Measurement range
2. Measurement accuracy
3. Use occasions
In general, you should pay attention to the following points:
a) It only needs to measure the distance within a range of more than ten meters, and the accuracy is not high.
Recommendation – optional ultrasonic range finder.
Remarks – The effect of ultrasonic range finder measurement is greatly affected by the environment, stability and directionality are worse than laser range finder, but the price is relatively cheap!
b) The measurement distance is not long, but the relative accuracy is high!
Recommendation – A short range laser rangefinder is available.
c) The measurement distance is far away, and it is mostly used for outdoor use!
Suggestion – purchase telescope laser range finder
(ie: long range laser rangefinder)!
Features – both telescopes and rangefinders! With multiple observation magnifications, the user can easily aim at the target for distance measurement simply by the cross aiming system inside the eyepiece! With 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!
