Golf is the so-called "green opium". When playing golf, you need to prepare a variety of equipment. Jerseys, caps, clubs, bags, clubs and more. Anyone who has played golf knows that such a situation is often encountered: one shot is overshot, and this shot is undershot. The golf course is uneven, with both uphill and downhill, and bunkers. How much does it take to get out of this shot? The prerequisite is to have an accurate judgment on the distance.
The principle of the laser rangefinder is to use the propagation speed of laser or infrared rays in the air to calculate. When working, it shoots a very thin laser beam to the target, and the photoelectric element receives the laser beam reflected by the target, and the timer measures the time from the launch to the reception of the laser beam, so as to calculate the distance.
It is very simple to use, aim at the target, press the button, and the distance can be read out. The accuracy of the laser rangefinder is high. No other auxiliary information such as stadium maps is required.
