How Does a Golf Rangefinder Work?

The main purpose of a golf rangefinder is to determine the accurate distance to fixed objects on the course. Besides the fact that these devices are easy to use and understand, they can also help you improve your game and achieve better results. The rangefinders are a great choice for both professional and amateurs, being exactly what you need to get the right distance to the flag without guessing. What is great about such devices is that they offer you reliable data in no time, so you can concentrate more on your shots and less on determining the distances to the targets. There are many players who decided to invest in a rangefinder due to the fact it comes with many advantages, this device being very popular among those who want to take their game to the next level. So, if you’re considering buying a golf rangefinder or you have just purchased one and you want to know more about how it works, we have gathered some information that will help you understand more about this technology.

To begin with, you have to know that there are two types of rangefinders and even though they work on the same principle there are some differences between them. The two available devices that are specially designed to offer you an accurate distance are the GPS rangefinders and laser rangefinders. Let’s find out more about each of them.

GPS Rangefinders

As their name suggests it, these particular devices use GPS technology and usually, they are more expensive than the laser ones. However, some people consider that using a GPS rangefinder is a little bit more complicated because you need to load the golf course map from a computer before starting the game. At the same time, with some models, you may need to subscribe to a monthly service in order to get the courses which means that you have to pay extra fees. Once you get on the course field, the device will acquire the GPS satellite feed and will provide you accurate distance to the available targets.

Laser Rangefinders

In what concerns this type of rangefinders, it emits a laser beam to the target and you can only use it to determine distances for targets that are visible. After you look through the lens of the golf rangefinder, the distance readout will be shown on the display. Additionally, you don’t need any computer system and you don’t have to pay any additional fees. From point of view, the laser rangefinders are more practical, being preferred by many golf players. Next, we will present you the main features of a laser rangefinder and what exactly they do in order to improve your game.

  • Slope Detection
    With the help of a built-in inclinometer the device determines the level of the slope, so besides the distance to the pin, you will also know the elevation change to the pin. Therefore, due to the fact that this feature shows you elevation adjusted distances to a particular hole, the rangefinders with this feature are not legal for tournament play.
  • PinSensor Technology
    Also named PinHunter and First Target Priority Mode by some manufacturers, this feature is very helpful because it basically measures the distance to the target by overlapping objects that may interfere with it. Therefore, even if there are objects in the background, the device will ignore them, focusing only on the target.
  • Jolt Technology
    This technology can be found only on some models and it’s quite innovating. So, every time the device locks onto the flag, you will be announced by short vibrating pulses. In this way, you will know for sure the rangefinder has isolated the target.
  • E.S.P.
    The E.S.P. or better said Extreme. Speed. Precision. is a feature that provides more accuracy to the player, rendering the results much faster. So, when it comes to distances up to 125 yards, you will have an accuracy of 0.1 yards.
  • Distance Range
    Most devices can measure more than 400 yards, some of them being capable to determine accurate distances up to 600 yards or even more. The maximum distance range is very important because you will know the maximum distance covered by the device. Therefore, when you’re looking for a golf rangefinder you definitely have to consider the distance range, especially if you want to cover larger distances.
