Compared with other ball games or entertainment, golf has its own speciality. The manufacturer of the Metek golf rangefinder emphasizes that, especially with its relatively large field size, it is difficult to judge the distance of a goal with the naked eye. Therefore, it is necessary to use some equipment for observation, for example, golf rangefinder is a commonly used equipment, according to different principles, the instruments are also divided into the following types.
1. Laser rangefinder.
The application of laser is the highlight of this type of golf rangefinder, which can use the reflection principle of laser to obtain a more accurate distance of the target object. In addition, the distance on the golf rangefinder side is relatively large from far to near, and you can make corresponding choices according to your needs, such as short-distance handheld and long-distance telescope laser rangefinders, which can reach hundreds to several kilometers. distance.
2. The ultrasonic rangefinder.
During the measurement process, the golf rangefinder mainly transmits ultrasonic waves to reach the target object without reflection, and calculates to obtain the relevant distance. Therefore, it can be said that its principle is actually similar to the laser rangefinder, but the golf rangefinder manufacturer reminds that since the ultrasonic wave may be affected by the surrounding environment, the measurement distance is relatively short and the accuracy is not high, and it is more suitable for short-distance measurement. relatively low.
3. Infrared rangefinder.
According to the golf rangefinder manufacturer, the infrared rangefinder emits special infrared light to the target object and reflects it back, records the time, and then calculates the distance. The measurement range of the instrument is generally 1-5 kilometers. Infrared light does not spread during propagation, so it can be emitted farther, but because it has a certain refractive index, it can only be used for close-up measurements, but golf rangefinder manufacturers have found that the instrument also has its advantages, That is, it is easy to produce, safe and cheap, etc.
