Laser rangefinders are useful in many areas of activity because they allow you to measure distances precisely and quickly. What is worth knowing about this helpful device? What forest rangefinders can be recommended?
Laser rangefinder - what is it?
A laser rangefinder is an extremely precise measurement device, which is why it is useful wherever accurate measurement results are needed, especially during construction, renovation and finishing works, but also in many other areas, such as energy, forestry, agriculture, hunting, sports, etc. It is invaluable in any task where the most precise measurements of distances, angles or terrain slopes are crucial.
Laser rangefinders are modern measuring instruments, definitely more innovative than optical and ultrasonic models. They tower over them in terms of functionality and technological advancement. Thanks to this, they provide extremely precise measurements of +/- 1-5mm/km. Moreover, they can be operated by one person, and not, as in the case of optical rangefinders, by at least two people. This not only speeds up and improves measurement work, but also facilitates matters related to staffing needs.
But that's not all, because laser rangefinders offer much more. It is also worth mentioning that they are less susceptible to measurement errors, regardless of whether they are committed by the operator (e.g. incorrect leveling of the device) or result from other reasons. Especially since most laser rangefinders are equipped with an auto-calibration function.

Laser rangefinders - how do they work?
The principle of operation consists in sending an electromagnetic pulse through the optical-electronic system, which takes the form of a laser beam. It is reflected from the measured plane and then returns to the rangefinder. Next, the beam is processed and thus the measured distance is determined. In phase laser rangefinders, the measurement is calculated based on the travel time of the section in two planes (based on the measurement of the phase shift of the transmitted and returning EM wave).
There is also another way to do it, which involves pulse laser rangefinders. This determines the direct time that the impulse needs to travel between the rangefinder and the object and between the object and the rangefinder. Laser rangefinders are also available that perform interferometric distance measurements, which provide by far the most precise and at the same time fastest way to measure distances. The problem is that these types of laser rangefinders cost quite a lot and are quite delicate, which makes them easy to damage. This excludes them from field research.
