Every kid dreams of being able to see in the dark, but now your a adult its time to make dreams come true and find yourself a pair of high tech night vision goggles. It can be quite intimidating when picking such a complex electronic device but do not worry, here is a handy guide to help you.

The first decision you need to make is the specific type of night vision equipment you require. They come in two types; these are thermal or image intensifying. Both have good and bad points and come with differing price tags. Going with the wrong one might be a costly error.

Thermal night vision goggles are adept at seeing the heat lines around the objects in the view finder. They assign differing heat colours to enable you to differentiate things. They usually work at their best when used to locate animals and living creatures that let off a large heat signature. This variety is generally used by law enforcement operatives.

The second main style of NVG’s are thermal based. These read the heat given off by items and assign them a colour based on the hotness. The hotter it is the brighter the light. This style of night vision equipment works at its best when used to find and track down small mammals, they’re also the NVG of choice for police officers who use them to find criminals.

The shape of your night vision device will differ wildly depending on its primary role and purpose, hunting equipment for example will come in the shape of a scope. The armed forces use eye mounted devices that fit onto the helmets of soldiers to enable them to find the enemy without using their hands to see.

The quality of the image you NV equipment provides is largely dependent on the quality and price of the item you’re using. One factor you’ll want to be aware of when selecting your night vision equipment is the resolution. In brief this is the quantity of lines the display produces. The greater resolutions return the greater images and therefore, the greater the price.

The range of your device is important, even more so for hunters who need to spot things at distance. The overall range you can see with the night vision goggles should be printed in the specifications. If not expect the shop assistant to clarify for you.

Range is also important, especially for hunters who need to see prey from a higher distance. The max range on most goggles should be printed plainly in the spec and you should aim to buy a pair of goggles with at least 550 feet of effective range.

As you can see there’s a lot to think about when buying something as expensive as this and not a decision you can make frivolously. Remember to try to pick your night vision glasses based on your needs and not because you want to look like Rambo!
