There was a time not that long ago when the only people who used night vision equipment where seen in Hollywood films, and they generally fell into two categories. They were either military personnel who used night vision equipment to track down the enemy, or they were some kind of sinister character who used night vision opticals for nefarious purposes. But all that has changed now, and night vision equipment is used for a wide variety of reasons by people in all walks of life. If you are an ornithologist, you will have a good set of bird watching binoculars which allow you to observe birds during the day. But binoculars are useless after dark, and this is just one reason why bird watchers use night vision equipment. Other people who are interested in wildlife have taken to using night vision equipment to help them keep track of badgers and other nocturnal animals, but the uses are not confined to those interested in wildlife.
One particular group of people who have welcomed night vision are those who go sailing in small vessels. While most vessels are fitted with spotlights, these are ineffective in the inky blackness of the sea. Night vision equipment allows sailors to have a 360 degree view of what is going on around them, reducing the risks of collision during darkness. Sherwoods Photographic sell a wide range of optical equipment, including telescopes, binoculars and of course, night vision equipment. Whatever you are looking for when it comes to optical equipment, they will be able to help.
