What is a Laser Rangefinder and How It Works?
Laser rangefinders for hunting significantly facilitate the hunter process of determining the distance to the target. And, accordingly, increase the effectiveness of hunting. However, choosing a rangefinder is not so easy. After all, modern laser rangefinders have a lot of useful functions and allow not only to determine the distance, but also to determine the speed of movement of the object and even calculate the coefficients of falling bullets. Let's figure out what to look at when choosing a rangefinder.
The modern hunter is lucky: he has high-precision weapons, clothing made from high-tech materials, and a number of instruments that facilitate hunting. One such device is a laser rangefinder - an electron-optical device designed to quickly measure the distance to a target or target. Range finders for hunting have multiplicity (2х-8х), high-quality optics with clearing and aiming grid and are certainly equipped with a digital processor. The presence of OLED-display allows you to use the range finder in sub-zero temperatures.
Which Rangefinder Functions Should a Hunter Pay Attention to?
Choosing a rangefinder for hunting is not an easy task, choose devices with useful functions, for example:
- Ballistic calculator for making corrections depending on the caliber of the weapon;
- angle meter for angular range compensation;
- measuring distance to moving objects;
- determining the speed of movement of the object.
However, most hunters feel fine with a laser rangefinder with a standard set of functions and modes.
Learn more about the principle of the rangefinder work
How laser rangefinder works? It uses the principle of lidar-the technology of obtaining and processing information about distant objects with the help of active optical systems using the phenomena of light reflection and its scattering in transparent and semitransparent media.The laser beam goes to the object, the computer records the time of passage of the beam to the object and back to the rangefinder, adds, multiplies by the speed of light in a vacuum, divides by twice the value of the refractive index of the medium (they contain mode settings), the result of division is the distance from the hunter to the object.
As a rule, the accuracy of the rangefinders for hunting is usually 1 meter, which is quite enough for accurate shooting and greatly simplifies the calculation of vertical corrections, whether determining the distance to the object in an open space or in a more complex terrain.
