How to choose a good rangefinder correctly?
Here are a few things to consider when buying a rangefinder:
1. Measuring range
2. Measurement accuracy
3. The occasion of use
Basically it is divided into the following situations:
a) Only need to measure the distance within a few meters or a dozen meters,
And when the accuracy requirement is not high.
*Recommendation - "Ultrasonic Range Finder" is optional.
*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, the ambient light is not complicated, and the accuracy is required to reach the millimeter level
*Recommendation - "Phase Laser Rangefinder" is optional.
*Remarks - The phase laser rangefinder is suitable for indoor use, and the measurement accuracy can reach below 2 mm.
(For example, when the user needs to detect in an outdoor environment, due to the influence of ambient light, it is necessary to add a professional laser sight and reflector, which can be used in combination 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: 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 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!
e) Measurement of long distance and outdoor measurement
*Recommendation - buy with built-in telescope, so that you can see more clearly in strong light.
*Note - for ease of measurement.
Problems that need to be paid attention to when using the laser rangefinder: The laser rangefinder cannot be directly measured at the human eye to prevent damage to the human body. At the same time, the general laser rangefinder is not waterproof, so you need to pay attention to waterproofing.
