Night vision goggles, simply put, allow us to see despite dark surroundings. However, the main difference with night vision goggles and thermal imaging units is that the former still needs some source of light, no matter how faint.
These systems have been used mostly in the military setting, allowing individuals to see targets without giving away their position. There have been plenty of night vision goggles in the market, and one unit that have stood out from the other units is the outstanding GPG-000-A19 from EOTech.
Unlike most night vision goggles that sport simple single or dual scopes, this unit from EOTech is fitted with four Gen III MX-10160 I2 tubes that are strengthened and ruggedized for excessive environmental usage. Clearly designed for strenuous outdoor activities, its well-built structure is waterproof and can withstand a 1 meter immersion for up to 2 hours. It is also meant to be mounted on a helmet using an NVIS mounting system. The weight of the GPNVG is approximately 1.7 pounds, making it lightweight enough to be carried around easily without you or your neck getting tired. To be fully operational, this goggle system requires four DL123 Lithium batteries and can keep the unit working for up to 8 hours of continuous use.
Designed to give you an increased visual awareness, this exceptional night vision goggle system boasts of a whopping field of view at 97 degrees (H) x 40 degrees (V). It also features an objective lens focus of 18” to infinity. There is no built in diopter technology with this unit, but it comes with a snap-on diopter window with an adjustable range of +0.5 to -2.5.
One special feature that sets this system apart from all the others is that you can detach individual monoculars from the setup, providing you with a compact, hand-held night-vision goggle. Individual monoculars are powered by an included power adapter. It also offers various settings that can be adjusted, such as Interpupillary adjustments, Tilt and Fore options, and Aft changes.
In summary, this night vision goggles pack a definite punch in the visual field by offering you a wide field of view that is not seen with other units, and this feature seems to be the main selling point of the system. However, its hefty price tag may or may not dissuade individuals from purchasing this unit.
