People often ask, how to measure distance with a rangefinder?
Let’s find out!
How to Measure Distance With a Rangefinder?
To measure the distance with a rangefinder follow these steps.
- Choose Measure by tapping the Menu button.
- Tap Measure laser points.
- The point’s name and a code must be entered.
- Choose the Start point from which you are measuring the laser point, or use the attached GNSS receiver to measure a new point.
- Put the target height and the laser height here.
- Before taking a measurement with the laser, give it a moment to settle.
- Tap Measure.
- To determine how close you are to your target, use the laser rangefinder.
- The Measure laser points screen displays the measurement’s specifics.
A rangefinder uses light waves to determine the distance between two points. This method works best at night because it doesn’t require any artificial lighting. It’s also useful if you want to check distances from tall buildings or trees.

Laser Rangefinder
Laser Rangefinders use lasers to measure distances. Long Range Laser Rangefinders are capable of measuring distances up to 20km. Laser Rangefinders are mounted on tripods with angular mounts. Laser Rangefinders provide azimuth elevation. Laser Rangefinders operate on the time of flight method.
Pulse
The rangefinder is designed to detect objects within a certain distance. The pulse may be coded to prevent jamming. Using Doppler effect techniques, an object can be detected as it moves towards or away from the sensor.
Precision
A laser-ranging device measures the distance to objects based on how long it takes light to travel to them. Laser-ranging devices use lasers to measure distances.

Range and Range Error
Beam spreading is a problem when using lasers. Air bubbles act as lenses, causing beam divergence. This means that the beam spreads out over time. Scintillation occurs because of turbulence in the atmosphere. Beam wander causes the beam to move up or down depending on whether the beam is moving towards or away from the ground.
Distortion and divergence of the laser beam make it hard to measure distance accurately. In open areas, there might be too much distortion and divergence of the laser beams.
In closed areas, the laser beams might be blocked by objects such as trees, bushes, etc.
Laser light reflected off leaves or branches gives a lower reading than the actual distance. Over long distances, the target disappears into a mirage.

Calculation
Laser range finding is based on the principle of time-of-flight. The distance between two points is calculated using the speed of light and the time taken for the round trip. The phase delay caused by the light traveling is used to calculate the angle of the beam.
This is the formula used to calculate the distance of an object from the source of sound waves. The distance is calculated by dividing the speed of sound into two parts.
The first part is the speed of sound divided by 2. The second part is the phase difference between the sound waves traveling back and forth.
Industrial Production Processes
Laser rangefinders are used by the steel industry to automate the process of measuring the distance between two objects. This allows them to determine how much material needs to be produced.

Conclusion
Laser Rangefinders are used in many industries. Construction, Renovation, Real Estate, etc. A laser Rangefinder can measure objects accurately without having someone else holding the tape.
Laser Rangefinders can calculate areas, volumes, and other basic measurements. Laser Rangefinder can be calibrated to use either Imperial or Metric Units.
