Here are a few things to consider when buying a rangefinder:
1. Measuring range
2. Measurement accuracy
3. The occasion of use
It is 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 Rangefinder" can be used.
*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! It is suitable for indoor measurement.
b) The measurement distance is not long, and it is mostly used indoors, with high precision requirements!
*Recommendation - Optional "Handheld 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, and use them together to achieve the expected range and effect.)
c) The measurement distance is far, and it is mostly used for outdoor use!
*Suggestion - buy "telescopic laser rangefinder" (ie: laser rangefinder telescope)
*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 aiming system inside the eyepiece! Use the transparent infrared rays that are harmless to the eyes Laser emission and reception, can accurately measure the target distance, its small size, light and easy to carry!
e) Measuring long distances and outdoor measurements
*Suggestion - buy a built-in telescope, so that you can see more clearly in strong light.
