How is a rangefinder used in agriculture


Laser rangefinders are indispensable measurement tools that come in handy during construction work, renovations, finishing, in the military, forestry, sports, power industry, hunting, agriculture and everywhere else where quick and precise distance, angle, or slope measurements are required.

For example, machines used to pick crops from fields can be guided using laser rangefinders to detect the height of the crops relative to the ground. Here, the picking apparatus is constantly adjusting its height based on instantaneous crop height to maximize yield and minimize waste.

Rangefinders provide an exact distance to targets located beyond the distance of point-blank shooting to snipers and artillery. They can also be used for military reconnaissance and engineering. Handheld military rangefinders operate at ranges of 2 km up to 25 km and are combined with binoculars or monoculars.

Which type of laser is used as rangefinders?

Series 8 and Series 9 have their highest sensitivity at 650 to 850 nm or 905 nm and are used in many laser rangefinders. Series 10 is particularly suitable for all applications using Nd:YAG laser beam sources at 1064 nm.

What is optical rangefinder in surveying?

A rangefinder (also rangefinding telemeter or simply telemeter, depending on the context), is a device used to measure distances to remote objects. Originally optical devices used in surveying, they soon found applications in other fields, such as photography and in the military.

A range finder is a binoculars/ monocular type device used to measure distance between its observer and a target.


Rangefinders are usually used in golf, ballistics, hunting, forestry and virtual reality. There are many reasons why you may feel the need to use a rangefinder, for example, if you are hunting in the wild, a hunting rangefinder will help you adjust your aim to account for the drop of bullet at relatively longer distances.


There are many different types of rangefinders, however, three among them distinctly stand out. These include, Laser, Optical and GPS rangefinders. There are other less used/ purpose-specific types too that include radar, lidar, sonar and ultrasonic rangefinders. We will remained focused on.


Each of the different types of rangefinders, whether cheap or pricey works in its own specific way. We will illustrate here the working mechanism of the main types of rangefinders.

Why use a laser rangefinder?

That’s why using a laser rangefinder lets you reduce staffing requirements and significantly speed up measurement processes.

How far can a laser rangefinder be used?

Professional construction laser rangefinders can measure distance of up to approximately 150 metres. Long-range rangefinders can measure distance of up to 1500 metres. These rangefinders are mostly used in hunting, agriculture, forestry, and the construction of roads.

How to measure distance with laser?
