Classification and selection of laser rangefinders
Laser rangefinders include ultrasonic rangefinders, handheld laser rangefinders, and laser rangefinder telescopes (telescopic laser rangefinders). First, determine your measurement range; second, determine measurement accuracy; third, use occasions. When purchasing, pay attention to the following points:
1. If you only need to measure the distance within a range of a few meters or ten meters, and the accuracy requirements are not very high: you can choose an "ultrasonic distance meter". Since the measurement effect of the ultrasonic rangefinder is greatly affected by the environment, its stability and directionality are worse than that of the laser rangefinder, but its price is relatively cheap! More suitable for indoor measurement.
2. The measurement distance is not long, and it is mostly used indoors. When the precision is high: "Handheld Laser Rangefinder" can be selected. This type of rangefinder is the most suitable for indoor use, and its measurement accuracy and effect are very good!
3. Long-distance measurement, mostly used for outdoor use: optional "telescopic laser rangefinder" (ie: laser rangefinder telescope). It is 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. It uses the transparent infrared laser emission and reception that is harmless to the eyes, can accurately measure the target distance, and is small in size, light and easy to carry.
4. Measuring long-distance and outdoor measurement: You can choose a built-in telescope, so that you can see more clearly under strong light. Because it is convenient for precise measurement.
Precautions when using the laser rangefinder: The laser rangefinder cannot be directly measured at the human eye 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 when using or storing.
The above are some tips that need to be paid attention to when purchasing and using the laser rangefinder. For specific use, please refer to the product manual and manual.
