How Does Your Golf Rangefinder Work?

Your golf rangefinder is an amazing tool which helps you a lot in picking up information about the distance of the field, the terrain, the obstacles you might be facing and sometimes even the speed of the wind. With one, you would have to spend less time making your shots but with high precision.


Understanding how your golf rangefinder works is just as important as having one. As you will be able to utilize all the functions of your machine and make your games even better. Most of the times, people use a laser golf rangefinder when they are on the field. This type is quite light and efficient compared to other models. So, let’s have an overall look of how these little guys work.

All laser rangefinders share a same working method: transmission of a laser beam. Basically, what they do is that when you press the button (after aiming to the spot where you want to measure the distance), the rangefinder shoots out a beam of laser toward that targeted location. After the beam has reached the location, the rangefinder will measure the distance from itself to that location by calculating the distance through the time the laser travelled.

Rangefinders are used in many circumstances other than on the golf fields; you can see one in the hunting rifles, in army’s binoculars, in a bag of an engineer, etc. However, apart from all the convenience that it may offer, there are certain drawbacks that are difficult to avoid when we use our rangefinder. Keep in mind that even the best golf rangefinder can still be faulty as time. The most common problem would be the result distance can sometimes vary.

Huge variation in the distance can be found when you measure a spot more than two times in a row. Usually, the further the target spot is from you, the larger the variation gets. There are many reasons behind this: it could be because of you or the rangefinder itself. Sometimes, when pressing the button, something may cross by and obstruct the flow of the laser beam so you would get an incorrect result.

So in order to maximize the efficiency of your rangefinder it is recommended that you:

  • Invest in a decent laser rangefinder with good quality and has a lot of positive reviews
  • Buy one with low laser beam divergence. This means that no matter how far the beam travels, it won’t spread out too much (instead, still focus at one small spot). You can actually ask someone to test it with you by telling them to stay far away and observe the end of the beam.
  • Be still when you are measuring. It means that from the moment when you press the button to the moment when the result is displayed on the machines, you need to be perfectly still. If you only move a little, the result can still be changed a lot because it results in large movement at the other end of the beam.
  • Measure more than one with different position. I always do it once when I’m standing and once when I sit down. It assures that I won’t be blocked by something I don’t see.
