Guide to buying a rangefinder
Points to consider when buying a rangefinder:
1. Measuring range
2. Measurement accuracy
3. Place of use
Basically, it is divided into the following situations:
a) It only needs to measure a distance of a few meters or ten meters, and the accuracy requirements are not high.
*Recommended-"Ultrasonic rangefinder" can be used.
*Remarks——The measurement effect of ultrasonic rangefinder is greatly affected by the environment, and the stability and directionality are worse than that of laser rangefinder, but the price is relatively cheap! Suitable for indoor measurement.
b) The measuring distance is not long, the ambient light is not complicated, and the accuracy is required to reach the millimeter level
*Recommended-"Phase Laser Rangefinder" can be purchased.
*Remarks——The phase laser rangefinder is most suitable for indoor use, and the measurement accuracy can reach 2mm or less.
(For example, when the user needs to detect in an outdoor environment, due to the influence of ambient light, it is necessary to install a professional laser sight and reflector, and use them in combination to achieve the expected range and effect.)
c) Long measuring distance, mostly used for outdoor use!
*Recommendation-purchase "telescope laser rangefinder" (ie: laser rangefinder telescope)
*Function-telescope and rangefinder! With multiple observation magnifications, users only need to use the cross aiming system in the eyepiece to easily aim at the target for distance measurement! Using transparent infrared laser emission and reception that is harmless to the eyes, it can accurately measure the distance to the target, and it is small in size, light in weight and easy to carry!
e) Measuring long distance and outdoor measurement
*Recommendation——Buy built-in binoculars to see more clearly under strong light.
*Remarks-convenient and accurate measurement.
Points to note when using laser rangefinders: Laser rangefinders cannot be aimed at the human eye to measure directly to prevent harm to the human body. At the same time, general laser rangefinders are not waterproof, so you need to pay attention to waterproofing.
