Rangefinders

A rangefinder is a device which measures the distance from the user to a target. Most modern rangefinders use a laser to calculate this distance, providing a reading in a few seconds.

They are often used for activities where knowing the distance to an object can be useful such as wildlife observation, golf, navigation and outdoor recreation.

How Does A Rangefinder Work?

Most rangefinders work by firing a laser beam at a target.

The device measures how long it takes for the laser to bounce back and uses this information to calculate the distance. The result is then shown on the viewfinder or an internal screen.

The process is almost instantaneous and can often yield measurements with a high degree of accuracy.

Why Do People Use Rangefinders?

It can be hard to judge distance, especially when the land is open. A rangefinder takes the guesswork out by giving an accurate measurement.

This can be useful for watching wildlife from a distance, for navigating unfamiliar terrain or for simply satisfying your curiosity about how far away an object really is.

A rangefinder provides many outdoor enthusiasts with information that is not easily judged with the eye alone.

Are Rangefinders The Same As Binoculars?

A standard rangefinder is designed to measure distance but many models also have magnification to help users see the target more clearly.

There are some devices that combine binoculars and range finding technology in one unit. They are often called rangefinding binoculars and allow the user to see and measure distance simultaneously.

How Far Can A Rangefinder Measure?

Maximum range varies from model to model. Some rangefinders are designed to measure short distances, while others can measure targets hundreds or even thousands of metres away. Performance may vary based on factors such as weather, size of target and reflectivity of surface being measured.

What Features Should You Consider?

When comparing rangefinders, it can be useful to look at:

• Maximum range
• Magnification
• Measurement accuracy
• Display type
• Weather resistance
• Battery life

The most important features will depend on how the rangefinder is supposed to be used.
