Leupold Rangefinder Buying Guide

Laser rangefinders are extremely precise devices, ideal for replacing the tape measure in daily chores, but also for large projects. They are used in outdoor sports such as golf and are highly appreciated by hunting enthusiasts. To help you choose the best one on the market, we explain everything you need to know about them.

What Is a Laser Rangefinder?

A laser rangefinder is a measuring device that uses a laser beam to determine the distance from your position to a specific point, typically determined by an object. The most common type of laser rangefinder works according to the “flight time” principle, sending a laser pulse in a narrow beam towards the target.

Due to the high speed of light, this technique is not suitable for high precision submillimetric measurements, where triangulation and other techniques are often used. A powerful laser rangefinder can measure up to 20 km mounted on a tripod with an angle bracket.

What Is Azimuth and What Is Its Relationship with The Laser Rangefinder?

Azimuth is the angle formed between the reference direction and a line between the observer and a point of interest on the same plane as the direction. Refers to an orientation angle on the surface of a real or virtual sphere.

The precise meaning of the term has particularities according to the discipline in which it is used. In astronomy, azimuth is the angle or length of the arc measured on the celestial horizon that forms the northern cardinal point and the vertical projection of the star on the horizon in latitude.

It is also used in boating – where it can be magnetic or compass – and in cartography, where it is measured from the north cardinal point.

What Range Can a Laser Rangefinder Have?

Even if the beam is narrow, it spreads over long distances due to the divergence of the laser, as well as the synchrony (explained below), and the effects of the beam in the beam caused by the presence of air pockets that act as lenses, with dimensions from microscopic to half the height of the laser beam path.

The compact models, designed for internal measurements and similar to laser meters, can measure up to 50 meters without problems. Outdoor laser rangefinder models have much higher capacities, from 600 meters to 20 km away, provided there are no obstacles.

What Is Synchrony?

Synchrony is a phenomenon by which the beam of a laser beam is dispersed. This occurs when the laser beam hits an air pocket that fragments it. it can also happen when lasers are used in sunlight if it falls directly on the beam, which spreads causing the loss of part of its force.

What Technology Do Laser Rangefinders Use?

Rangefinders are capable of making complicated measurements at very long distances. Unlike other instruments, not only do they measure distances, but they can measure direct and indirect lengths, volumes, and areas, all in a very simple way. for this purpose they use technologies that are detailed below:

  • Timed flight: measures the time it takes for a pulse of light to reach the target and return. Knowing the speed of light and with an accurate measurement of elapsed time, you can calculate the distance. Several pulses are activated sequentially and the average response is the most frequently used. This technique requires very precise subnanosecond timing circuits.
  • Multiple frequencies: this technology is used to measure the phase change of multiple frequencies when reflected, then solves some equations simultaneously to provide a final measurement.
  • Interferometry: the most accurate and useful technique for measuring distance variations instead of absolute distances.

What Uses Can a Laser Rangefinder Have?

Laser rangefinders can be used for various things. As mentioned earlier, compact models are used for DIY or construction work. They are also often used for cartography, 3 d modelings, sports such as golf or archery, hunting, and in all types of industrial production processes.

Here is a detailed list of the most common uses of laser rangefinders.

  1. Military: laser rangefinders offer an exact distance between targets beyond the actual range of artillery. They are also used to delimit areas and for military engineering works. They measure azimuth, tilt, height, and length.
  2. 3 d modeling: they are used for the recognition and modeling of 3 d objects and in other areas related to artificial vision. This technology is somewhat superior, as it usually includes 3 d scanners with 360 ° vision. They have algorithms that combine the distance data of a single object obtained from multiple angles.
  3. Forestry engineering: special laser rangefinders are used for this job. the laser beam is only reflected in its retroreflector, so exact distance measurement is guaranteed. Laser rangefinders with leaf filters are used for forest inventories.
  4. Sports: they are very effective for sports that require very accurate long-distance measurements. They are mainly used in golf, hunting, and archery. Many rangefinders have advanced features such as cad (distance angle compensation) and multi-range capability.
  5. Topography: these rangefinders are used in the construction of roads and forensic measurements for construction projects. They are very similar to forest engineering models.
  6. Industrial production processes: it is used for the automation of raw material management systems and production processes in the steel industry.
  7. Instead of laser measuring instruments: they are used in many activities such as construction, DIY, and renovations. They are a good alternative to tape meters, they are more precise and practical since they measure angles and areas. They store information and their screen allows you to easily read the results.

How Does a Laser Rangefinder Work?

Its operation is based on the mathematical triangulation method. This method of triangulation distances on earth and astral distances were measured.

When using the rangefinder, a fixed distance is taken between two points, the one that exists between the sights and, with mechanical and optical means, the distance to the equivalent object is calculated.

The distance is calculated by adjusting the vision of two images that the viewfinder gives us the object. We observe the object, the distance of which is measured through two crosshairs, and in the eyepiece, we see two images that are not coincident, that is, disjointed.

How Accurate Are Laser Rangefinders?

A rangefinder that uses very sharp laser pulses and that has a very fast light detector, can determine the distance at which an object is found with a margin of error of a few millimeters, between 1 and 5 mm.

How Do You Use a Laser Rangefinder?

Rangefinders are used to measure distances without having to have physical contact with the points to be measured. This device manages to Determine the extension between two points with a very high level of precision. It is widely used in the industrial sector, but also in carpentry, construction, blacksmiths, and interior designers.

Below we show you how to use a rangefinder step by step.

  • Switching on: the first thing you should do is read the instructions for use, to know the accessories. Install the batteries and press the power button.
  • Screen interface plays a very important role, because it shows the results of the measurements, as well as providing us with information on how we use the equipment.
  • After turning on the device, you can check all the details and follow the indications of the interface.
  • Types of measurements: use the screen interface to choose the type of measurement you want to take.
  • Most models have options for measuring direct and indirect lengths, areas, and volumes.
  • Measurement: place the rangefinder and take measurements. Rangefinders incorporate bubbles to put equipment in the correct position, such as spirit levels. Once positioned, press the button to start the measurement and wait for the results to appear on the screen.
