How to Use Rangefinder Arma 3

How to Use Rangefinder Arma 3?

Arma 3 is the Bohemia Interactive’s fourth main game of the long-running Arma series. It was initially released as an Alpha on March 5, 2013, and was later on updated on June 25 of the same year.

The full version was released on September 12, 2013. More content was added in the form of three more episodes entitled Survive, Win, and Adapt.

Arma or Armed Assault rangefinders releases a laser beam at the push of a button. Once the beam hits an object, it will bounce off the surface or the terrain.

The rangefinder’s high-speed clock will then measure the amount of time it took when the beam left the unit to the time it returns to determine the distances on its target.

Take note that as compared to the beams emitted by infrared laser pointers or laser markers, rangefinders do not release visible beam under night vision or thermal scope in-game. They are making it safe to use if the priority is to avoid detection.

More Facts About Rangefinder in ArmA 3


When it comes to laser rangefinders, it is more detailed in Arma 3. It also provides the Azimuth and the elevation of a target, not just the distance. As compared to Arma 2, every faction can access the rangefinders as opposed to it as being exclusive to only Blufor.

For ground troops, the handheld rangefinders are recommended, and it is still available. Most of the armed vehicle platforms, as well as aircraft, has a rangefinder installed as part of its weapon’s targeting pod or FCS.

Some shoulder-launched weapons such as MAAWS Mk4 Mod 1 also have rangefinders, which makes calculating the distance to target much more accessible.

But handheld and vehicle rangefinders should be activated manually and do not scan the distance target continuously.

The process is simple, but you need to press the targeting key when aiming at a specific surface.

Functions of Rangefinder Arma 3


The rangefinder in Arma 3 will not just show you the distance to your target, but it also enables you to carry out a lot of things which is not available in others. Some of the functions of the rangefinder but are not limited to includes the following:

  • The angle between 2 targets
  • Azimuth to a target
  • Distance between 2 targets
  • Distance to a target
  • Horizontal and vertical distance to a target
  • Switching between degrees and mils …
  • Switching between feet and meters

Guide on How to Use Rangefinder Arma 3


Two keys control the rangefinder – the range key (R) and the azimuth key (Tab) and is brought up just like other binoculars.

Slope Distance

To determine the slope distance, Press the R key and hold until you see the red pointing circle. Sight the circle on the target and release the key.

Azimuth

To know the Azimuth, press the Tab key and hold until it shows up the Azimuth.

Azimuth and Slope Distance

If you need to measure both, press both Tab and R at the same time and hold until the red pointing circle shows up, focus the circle on the target, and then release the two keys.

Determining the Height Difference and the Horizontal Distance

To determine the height difference and the horizontal distance, press the R key once then press it again. This time hold it until you see the red pointing circle. Point the circle on the target and then let go of the key.

Determining the Azimuth and Inclination

In determining the Azimuth and inclination, simply press on the Tab key once then press it again and hold the inclination, and Azimuth shows up.

Measuring the Distance Between 2 Points

The distance between two points can be measured by pressing and holding the R key long enough for the red pointing circle to show up.

Focus the circle on the first item and then click the Tab key as you continue holding the R key. It confirms the first measurement. Do the same thing in measuring the second object and release the R key.

Assessing the Distance Between 2 Points Horizontally and Vertically

To measure the distance between two points horizontally and vertically start by pressing the R key once and hold it long enough for the red pointing circle shows up.

Vision the circle on the object and then press the Tab once. This will confirm the first measurement.

Vision the second object and stop pressing the R key.

Determining the Horizontal Distance and Azimuth Between 2 Points

In measuring the horizontal distance and the Azimuth between two points, you need to press and hold the tab key until the Azimuth shows up.

Vision the circle on the first object and then press the R key as you hold the Tab key. This will confirm the first measurement. Vision the second object and let go of the Tab key.

Visioning Fall of Shot

To measure the fall of shot, press the Tab key once then press again, this time hold it long enough until the Azimuth is displayed. Then vision the circle on the object and press the R key as you hold the Tab key. This will confirm the first measurement.

Vision the fall of shot and let go of the Tab Key. The left digits show the left key/right correction value in the meter while the right figures show the longer/shorter correction value in the meter. The height correction values are displayed if you press the R keys.

How to Set the Measurement Units (meters/feet and degrees/mils)?

Press the Tab 5x fast. It will show “UnitSEtt” briefly. Tap R long enough to display the desired units. Press Tab 5x fast to save the option.

Final Thoughts


For those who are new in using the rangefinder Arma3, you might find it complicated or a bit different from the others. The rangefinder is an essential part of the scopes and optics.

Through this, you can measure the distance between your target and enables you to shoot the object accurately. Knowing how to use it correctly will provide you a precise measurement that helps hit your target.
