Night Vision? Sure - I'll have some please...
From my limited experience, there are two main types of night vision - illuminated by infra-red (IR) light and thermal. And both have their pros and cons. Thermal is more expensive but it can see through environmental conditions like fog, smoke, rain, haze, etc. It also has a much greater "reach" being able to identify differences in heat out beyond 400 yards (367 metres). However, the picture or resolution is not as sharp as IR. For example, a calf at 400 yards, while visible as an animal, may appear to be a large boar. Being certain of your target is critical with thermal scopes. IR scopes, on the other hand, are just the opposite of what is stated above - less expensive, limited in range, cannot see well when the environment turns to crap, and has a clear, sharp picture. Strictly for the cost element, I dove into the IR night vision world. And I was able to get a scope, IR laser range finder, IR illuminator (flashlight) and quick detach rings for H...
