Night vision scopes have become a necessity for hunters and shooters who want to increase their chances of success in low-light conditions. If you’re in the market for a night vision scope, it’s essential to know which brands offer the best options. In this article, we’ll explore whether Vortex makes night vision scopes and what to consider when choosing the right one for your needs.

What is a Laser Rangefinder

A laser rangefinder is an instrument that uses a laser beam to determine the distance between two objects. It sends out a pulse of laser light that bounces off the target, and then measures the time it takes for the light to return. The rangefinder then uses this time to calculate the exact distance between the object and the laser. Laser rangefinders are small, portable and highly accurate, making them popular among professionals and amateurs alike.

How Does a Laser Rangefinder Work

A laser rangefinder is equipped with a high-powered laser diode that emits a short burst of laser radiation towards the target object. The laser beam reflects off the target and returns to the rangefinder, where it is detected by a sensor. The time taken by the laser beam to travel to the target and back to the device is then calculated by the rangefinder’s onboard computer.

To be more specific, the rangefinder’s computer measures the time between the laser pulse’s emission and its detection after bouncing off the target object. As the speed of light is constant, the distance between the target and the device can be calculated by dividing the time taken by the laser pulse by 2 and multiplying it with the speed of light.

Laser rangefinders are also equipped with a high-quality optical system that helps the user to visualize the target object precisely. The optical system of a rangefinder usually consists of a lens, an eyepiece, and a reticle.

Components of a Laser Rangefinder

Laser rangefinders are complex devices that come with various components. These components work in tandem to determine the distance between two objects. The laser module is the most important since it emits the laser beam. The rangefinder also includes a receiver lens, which captures the laser beam once it bounces back from the target. A quartz crystal comes into play, which helps stabilize the emitted laser beam’s frequency. The device’s processor interprets the information captured by the receiver lens and calculates the distance. Finally, the rangefinder’s display shows the calculated distance.

Benefits of a Laser Rangefinder

Laser rangefinders have several advantages over other measuring instruments. One of the most important benefits is their accuracy. Compared to traditional measuring tools like tape measures and rulers, laser rangefinders are highly accurate, making them ideal for tasks that require precision measurements. They are also easy to use and portable, making them ideal for fieldwork. Laser rangefinders are fast, reducing the time it takes to measure distances, and they are capable of measuring distances over long ranges.

Uses of a Laser Rangefinder

Laser rangefinders are used in various fields, including surveying, construction, hunting, and golfing. Surveyors use them to determine the length, width, and height of buildings, determine the grade of a slope or measure the distance between two points. Construction workers use laser rangefinders to measure distances between buildings and plot out construction sites. Hunters use them to determine the distance to their prey and aim accordingly. Finally, golfers use laser rangefinders to determine the distance between the ball and the hole and improve their game.

Types of Laser Rangefinders

There are primarily two types of laser rangefinders: First Priority and Second Priority.

First Priority

First Priority rangefinders are most often found in golfing rangefinders or range finders used for close proximity hunting. They usually have ranges from 50 to 1000 yards and measure only the distance to the first target they encounter. This first priority rangefinder is intended primarily for measuring the distance to a flagstick or other structures in the foreground.

Second Priority

Second Priority rangefinders are usually preferred for long-range hunting and include military rangefinders, outdoor professionals, and hunting rangefinders that are designed to reach targets over 1000 yards away. These rangefinders use different algorithms to filter multiple readings obtained from multiple targets and ensure accurate readings of only the second priority targets.

Tips for Using a Laser Rangefinder

To get the most out of a laser rangefinder, users should position themselves correctly, ensuring the rangefinder’s view is unobstructed. Users should also avoid using the rangefinder outdoors on bright days since sunlight can interfere with the laser beam. It is also essential to choose the right rangefinder based on the intended application, taking into account range, magnification, and accuracy. Finally, it is critical to follow the manufacturer’s instruction manual, ensuring that the rangefinder is correctly calibrated and maintained.

Common Mistakes to Avoid When Using a Laser Rangefinder

Users should avoid pointing the rangefinder at shiny or reflective surfaces such as water, glass, metal, or mirrors since these can interfere with the laser beam and skew the results. Users should also avoid using the rangefinder on objects that are too close or too far, reducing accuracy. Finally, it is important to ensure that the rangefinder’s battery is fully charged before use to avoid measurement errors.

How to Choose the Right Laser Rangefinder

Choosing the right laser rangefinder can be overwhelming, especially since there are so many options out there. Some factors to consider when making a purchase include range, accuracy, price, ease of use, and specific features such as slope and angle compensation.


Laser rangefinders are advanced instruments that have revolutionized various industries. They use laser technology to determine the distance between two objects accurately. These devices are fast, portable, and highly accurate, making them popular among professionals and amateurs alike.

The benefits of laser rangefinders are numerous, including their accuracy, speed, portability, and ease of use. Whether you are a construction worker, surveyor, golfer or hunter, a laser rangefinder is an indispensable tool that can simplify your work significantly.
