How Does A Laser Rangefinder Work

The first time someone used a laser rangefinder was likely in the early days of shooting video games. Since then, technology has come a long way, and you can find rangefinders in professional and recreational shooting circles. While they may seem like an old-fashioned tool, there are plenty of reasons to invest in a good laser rangefinder. In this article, we’ll explain how a laser rangefinder works.

How Does A Laser Rangefinder Work

How does a laser rangefinder work, it’s a question people ask often. A laser rangefinder is a device that uses lasers to measure the distance between the device and an object. Laser rangefinders typically use infrared lasers, which are invisible to the human eye. 

Once it makes contact with its target, that energy reflects towards the rangefinder in a “return signal.” Sophisticated circuitry inside then quickly calculates how long it took for that signal to come back — allowing for an extremely accurate reading of how far away your target is.

Laser rangefinders work by emitting a laser pulse and measuring the time it takes for the pulse to return to the device. Users can use this time to calculate the distance between the device and the object. 

Most laser rangefinders have two buttons: one for emitting a pulse and one for measuring the time it takes for the pulse to return. Some devices also have a display that shows the distance measured. 

Types Of Laser Rangefinders

Laser rangefinders have many different types. The most common are golf rangefinders, hunting rangefinders, and military rangefinders. Each type has unique features that make it better suited for a specific activity.

Golf Rangefinders: Golf rangefinders typically use a laser to measure the distance from the user to the target. This information is then displayed on an LCD screen. Golfers use this information to help them determine the correct club to use for their next shot.

Hunting Rangefinders: Hunting rangefinders are often designed with camouflage patterns to help them blend in with their surroundings. They typically use a laser to measure the distance from the user to the target, but some models also include an optical viewfinder for more accurate measurements.

Military Rangefinders: Military rangefinders are designed for battlefield conditions.

What Are Some Applications For Laser Rangefinders

Laser rangefinders have a variety of applications, including golf, hunting, surveying, and construction.

Golfers use laser rangefinders to determine the distance from the ball to the green. This information allows them to select the club with the appropriate loft for the shot. Laser rangefinders are also useful for measuring distances on short par 4s and 5s.

Hunters use laser rangefinders to measure the distance to their prey. This information allows them to make accurate shots with their bow or rifle.

Surveyors use laser rangefinders to measure distances between points to create maps or plans.

What Are Some Benefits Of Using A Laser Rangefinder

Militaries have used rangefinders for centuries, and the civilian population now realizes their benefits. Rangefinders can calculate the distance between an object and the user. This information is then used to provide an accurate measurement for whatever the rangefinder is pointed at. There are various applications for laser rangefinders that you can find in both the civilian and military worlds.

The use of laser rangefinders has a variety of benefits that include accuracy, speed, and distance.

  • First, the accuracy of laser rangefinders is precise within one meter. This level of accuracy is beneficial when measuring the distance to an object or trying to gauge how far away a hazardous area is.
  • Speed is another benefit of using a laser rangefinder. Laser rangefinders provide results much faster when compared to other methods such as using a map and compass or estimating distance.
  • Lastly, the distance that lasers can reach is farther than other methods. This allows people to measure distances more precisely, especially in areas where obstructions interfere with the view.


Laser rangefinders are a popular tool for hunters, golfers, and other outdoor enthusiasts. They accurately measure the distance to an object, making it easy to identify the target and make a precise shot. While laser rangefinders have many benefits, they also have a few drawbacks.

Laser rangefinders are not always accurate. The measurement can be affected by factors such as weather conditions, the angle of the object, and even the terrain type. It can make it difficult to hit your target, especially if you are shooting from a distance.

Laser rangefinders can also be expensive. They typically cost more than other types of rangefinders on the market. This can be a disadvantage if you are on a budget or only need a basic rangefinder for occasional use.

Can You Use A Laser Rangefinder When Golfing

Are you looking for an edge when playing golf? If so, you may be wondering if using a laser rangefinder is allowed on the course. In most cases, the answer is yes – experts allow using laser rangefinders in golf. However, a few things to keep in mind before using one.

First and foremost, check the course rules before using your rangefinder. Some courses do not allow their use, while others restrict where you can use them. Also, ensure that the USGA approves your rangefinder for tournament play, as some models are not.

Second, be aware of your surroundings and ensure you are not casting a shadow over the target.

Finally, ensure you are using the correct mode for measuring distance on a golf course.


In conclusion, a laser rangefinder emits a beam of light bounced off an object and then back to the rangefinder. The rangefinder then displays the distance. Hunters, golfers, and surveyors use these devices to measure distances. 

Thanks for reading! I hope this article helped you understand how a laser rangefinder works.
