A rangefinder is something used by the observer to measure the distance between himself and the target. These devices are very accurate and precise. A rangefinder’s main use is to help the hunter shoot accurately at a greater distance. Aiming using the rangefinder eliminates the complexity of lining up the shot. But now rangefinders are handy innovative devices manufactured to help golfers and archers to achieve greater accuracy. There are tons of high-quality rangefinders being developed. They offer great benefits for hunting, golf, archery and surveying. Below is a compilation of the best rangefinder reviews and guide .

Who Uses Rangefinders?


Hunters use rangefinders to calculate the distance between themselves and the prey. For a hunter to make an instant kill, he needs to determine the distance and tune his rifle accordingly. For more accuracy, the hunter pairs the rangefinder with a riflescope

How Do Rangefinders Work?

There are two types of rangefinders; Mechanical and Laser rangefinders.

Mechanical Rangefinders

These types of devices use optical technology and an eyepiece to produce two images of the object being measured. The device then merges the two images together. When this happens, the distance is read off the scale on the adjustment control.

Laser Rangefinders

A laser rangefinder bounces a laser beam off the target while just a press of a button. An internal clock then measures the time it takes for the beam to reach the target and back, and finally calculates the distance to within more than a yard or less. The laser range finder then displays the range on an internal LCD display.
