Night Vision Devices

By Carole Ashley


You get bright nights in the backcountry. A bright moon and a sky full of stars can throw off enough light to allow for reading a book, but add cloud cover, mountains or trees and it gets dark awfully fast. When this happens, you can either turn on a light or use a night vision device. Night vision devices might just be the best thing to happen to backcountry toys.

Choosing the right NVD will depend on how you'll use it. When most people think of night vision capabilities, they think about spy movies, the military or law enforcement - applications where it is vital for the good guys to see without being seen by the bad guys. Over the years, more and more people can afford NVDs. However, high-end devices used for specialized purposes remain quite expensive.

There are two main categories of night vision devices. Image Enhancement devices enable a person to see in the dark by collecting small amounts of light and amplifying them. Thermal Imaging devices get the high end of the infrared light spectrum that is given off as heat by objects. You get a clearer image with Image Enhancement devices, and images with regions of heat with Thermal Imaging devices. NVD has give generations as of today. With generation 0 and 1, poor image quality is produced, but the price is very low. The 2nd, 3rd, and 4th generation give better images and higher prices as the generation increases.

Applications for NVD are actually quite diverse. Some examples are: military, law enforcement, security, hunting, wildlife observation, surveillance, navigation, hidden-object detection, spelunking and entertainment. NVD can be found on helicopters, rifles, camcorders, cameras, boats....just about anywhere. There is even a new craze in up-scale gathering called "A Dinner in the Dark Party", which involves guests wearing NVDs the whole time.

People who go to the backcountry are finding the dark a great place for discovery. Getting a NVD is a good idea if you like camping, hunting, or hiking.
