What exactly is a golf laser rangefinder for?
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.
