The rangefinder is a device that measures the distance and other characteristics of an object using a laser. To do this, he uses the principle of flight time; the rangefinder sends a laser pulse in a narrow beam to a target and, depending on the target reflection time and the return time, the distance can be obtained. Rangefinders are popular among hunters, in various sports and with military personnel. We have researched and reviewed of the best hunting rangefinder from our pick.
Some models provide feedback on the release of the shot so that the user can be certain that nothing will interfere with his target. This can be particularly important for the military, as they use their rangefinder for life and death issues, and cannot afford to shoot the wrong target. Some also have high definition optics, which allows the user to examine their target closely on a small screen. Hunters and the military benefit from models that determine whether an object moves or not, and at what speed.
People who use a bow and arrows need a model with integrated tilt/decay technology and so military rangefinder is a good choice. This will take into account different shooting angles when calculating the distance. Night hunters need a laser rangefinder with an adjustable display screen for different lighting conditions. Some act as night vision devices, with a brightness control technology that provides eye contrast, changing with the surrounding light conditions.
The History Of Rangefinders
The very first rangefinder was called a micrometer. A man named James Watt invented it in 1769 and his version consisted of two parallel hairs that were inside the focal plane of a telescope eyepiece. A man named Alexander Selligue is sometimes credited with the invention of the rangefinder, and although he has developed the model that has become popular among the masses, he is not the original inventor.
In 1781 Georg Friedrich Brander made the coincidence rangefinder. These are two mirrors positioned horizontally that make two images in the same eyepiece. No matter who historians believe invented the very first rangefinder, most agree that it was born in the steam era. But at the end of the 19th century, electrical engineers applied the term rangefinder to devices they used to measure different quantities.
Several very different devices have been tagged at one point, including a resistance thermometer, which is used to measure temperature, and an electric strain gauge, which determines the amount of strain on an object. Because the term rangefinder was so widely used and its meaning had become blurred, the Institution of Civil Engineers suggested replacing it with the word tachometer.
During the Second World War, the boom in industrial development made tachometers commercially viable. These devices became especially important when humans began rocket and aviation research, as well as space exploration. Since spacecraft can lose contact with radio or electromagnetic waves, rangefinders were one of the only ways for people on the ground to measure vehicle parameters. The rangefinders have also played a role in the history of espionage. American spies during the Cold War used them to determine the location of Soviet missile tests.
WHICH RANGEFINDER FOR HUNTING?
The breadth of manufacturers, types of rangefinders, price ranges, applications, etc. is enormous and therefore, of course, the question arises which distance meter is optimal for you. Of course, there is no blanket answer here. However, it may be helpful to ask yourself a few questions before buying and to have a closer look at the offerings of the various models. Depending on your budget and scope, you may be able to make a quick decision.
