SPI BLACKBIRD 6X-NGEN3-B2

If you are using binoculars with 5.6x zoom to view an object that is 10 miles away, it will appear as if it is only 1.79 miles away. This is because the 5.6x magnification makes the object appear approximately 1/5.6th of its actual distance, effectively reducing the apparent distance. So, an object 10 miles away would look much closer, appearing as if it is 1.79 miles away when viewed through the 5.6x zoom binoculars.

Gen 3 IIT 3NL2 is the second best quality offered by SPI with very limited number of spots in Zone 1.

The rule is simple. Increase magnification, decrease field of view. When you crank up the power on your binoculars with long range infrared illuminator, you’re going to see less of an area as you get more specific detail on your target or scene. When you dial back down to low magnification, the field of view will become wider as you see more of the surroundings in your view.

A Field of View (FOV) of 7 degrees, for our best gen 3 night vision binoculars with long range infrared illuminator, means that you will be able to see a width of the scene that is calculated by multiplying the angle by 52.5. So, for an FOV of 7 degrees, you would calculate it as 7 degrees x 52.5 = 367.5 feet. This means you can see 367.5 feet of a scene from left to right when looking at a distance of 1000 yards.

The highest magnification in binoculars with long range infrared illuminator is typically around 20x to 25x, but extremely high magnifications may compromise stability and image quality.

A long-range infrared illuminator is a device that emits infrared light, which is invisible to the human eye but can be detected by night vision devices. This technology is often used to enhance the performance of night vision devices in low-light conditions, effectively increasing their range and detail. All of our night vision products, including our best gen 3 night vision binoculars, come with a long range infrared illuminator.

Here are some benefits and uses of long-range infrared illuminators:

Enhanced Night Vision: Infrared illuminators can significantly improve the performance of our best Gen 3 night vision binoculars, allowing for better visibility in low-light or complete darkness. This can be particularly useful for activities such as hunting, wildlife observation, or surveillance.

Undetectable Illumination: Since infrared light is invisible to the human eye, an infrared illuminator can provide light without alerting people or animals to its presence. This can be useful in surveillance or hunting scenarios.

Long Range: As the name suggests, long-range infrared illuminators can provide illumination over a greater distance than standard infrared illuminators. This can be beneficial in situations where the user needs to observe or target something from a distance.

Versatility: Infrared illuminators can be used in a variety of settings, including military operations, law enforcement, hunting, wildlife observation, and even paranormal investigations.

Safety and Security: Infrared illuminators can be used in security cameras to provide clear images even in complete darkness, enhancing the safety and security of properties.

Astronomy and Astrophysics: Binoculars with long range infrared illuminators are also used in the field of astronomy and astrophysics to study celestial bodies that emit infrared radiation
