A laser rangefinder is an instrument that uses a laser to accurately measure
the distance to a target. The laser rangefinder emits a very thin laser beam to
the target when it is working, and the photoelectric element receives the laser
beam reflected by the target. The timer measures the time from the emission to
the reception of the laser beam, and calculates the distance from the observer
to the target. The laser rangefinder is light in weight, small in size, simple
in operation, fast and accurate, and its error is only one fifth to several
hundredths of other optical rangefinders.
Purchase of Portable Handheld Laser Rangefinder
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 rangefinder" can be used.
Remarks - The measurement effect of the ultrasonic rangefinder is greatly affected by the environment. The stability and directionality are worse than that of the laser rangefinder, but the price is relatively cheap and 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 long, and it is mostly used for outdoor use.
Suggestion - buy "telescopic laser rangefinder" (ie: laser rangefinder telescope)
